$  3DJHRI4.2 Interface Functions 4.2.1 Scan for all BlueRobin devices on ports This function checks all ports for connected BlueRobin devices having the specified device type, it returns the number of connected devices and it generates an internal list with device details which can be accessed then using function rtxInterface_GetInfo(). bool rtxInterface_ScanForDevices(bmiDeviceType DeviceType, int &NoOfDevicesFound); Parameters: DeviceType Scanning for BM-USBD1: bmiDEVTYPE_USBD1 Scanning for BM-USBRTX3: bmiDEVTYPE_USBRTX3 NoOfDevicesFound Number of devices found with specified device type Return Value: Returns true if at least one device could be found, otherwise returns false 4.2.2 Get device information for a found BlueRobin device After having scanned all ports for connected BlueRobin devices of a specific device type using function rtxInterface_ScanForDevices() this function has to be used to get details for the found devices so that the desired device to be opened can be selected. bool rtxInterface_GetInfo(unsigned char DeviceIndex, rtxUsbDeviceInfo *DeviceInfo); Parameters: DeviceIndex Index into the device list generated by function rtxInterface_ScanForDevices(); starts at 0 and can be up to the number of found devices less 1 returned when scanning DeviceInfo Contains the device information for the selected device typedef struct rtxUsbDeviceInfo { unsigned short DeviceType; // Device type identifier char PortName[256]; // Port name char PhysName[256]; // Physical name char DevDescr[256]; // Friendly name char EnumName[256]; // Enumerator name char LocationName[256]; // USB bus location identifier char SerialNumber[256]; // Serial number unsigned short Vid; // Vendor ID unsigned short Pid; // Product ID } rtxUsbDeviceInfo; Return Value: Returns true if device could be found and its information is available, otherwise returns false 4.2.3 Start to detect if a BlueRobin device has been unplugged This function starts background checking if the specified BlueRobin device has been unplugged from the specified port. bool rtxInterface_UnplugDetectionStart(const char *PortName); Parameters: PortName String specifying the port name; will be returned as a part of the USB device information when calling function rtxInterface_GetInfo() Return Value: Returns true if BlueRobin device and port has been found, otherwise returns false Remarks: This function is in experimental state!$

  3DJHRI4.2.4 Stop to detect if a BlueRobin device has been unplugged This function stops any previously started check for an unplug event. bool rtxInterface_UnplugDetectionStop(void); Return Value: Returns true if detection could have been stopped, otherwise returns false Remarks: This function is in experimental state! 4.2.5 Signal an unplugged BlueRobin device This function should be periodically checked to see if an unplug event happened. bool rtxInterface_UnplugDetected(void); Return Value: Returns true if an unplug event has been detected, otherwise returns false Remarks: This function is in experimental state! 4.3 Device Functions 4.3.1 Open port Opens the port the BlueRobin transceiver hardware is connected to. The BM-USBRX3 hardware is powered up when opening the port. Some parts of the hardware require a start up time of up to 2 seconds so it could take up to that time to open the port. No start up time and therefore no delay can be seen for BM-USBD1 transceiver dongles. bool rtxDevice_Open(const char *PortName); Parameters: PortName String specifying the port name; will be returned as a part of the device information when calling function rtxInterface_GetDeviceInfo() Return Value: Returns true if port could be opened and transceiver hardware could be found, otherwise returns false Remarks: Do not try to open more than one port for a BM-USBRTX3 transceiver unit at a time. Always close the port first before trying to open the port again! 4.3.2 Close port A successfully opened port has to be closed at the end of the application runtime to release all allocated memory and the port itself. bool rtxDevice_Close(void); Return Value: Returns true if port could be found and closed, otherwise returns false 4.3.3 Check if port has been opened This function checks if a port to a BlueRobin device has already been opened. bool rtxDevice_IsOpen(void); Return Value: Returns true if port is open, otherwise returns false

$  3DJHRI4.3.4 Initialize BlueRobin hardware To initialize the connected transceiver hardware the following function has to be called once after opening the port and before any further access to the hardware is done. It also returns the number of available channels in RX mode. bool rtxDevice_InitHardware(unsigned char &MaxChannels); Parameters: MaxChannels Number of available channels Return Value: Returns true if the initialization was successful and false if accessing the hardware failed. Remarks: BlueRobin RX mode has to be configured first. 4.3.5 Get transceiver unit configuration and version info To get the number of configured channels in RX mode and the profile, ID and descriptor in TX mode (currently not implemented) the following function can be used. Also the serial number and the software and hardware revisions will be returned. bool rtxDevice_GetInfo(rtxDeviceInfo *DeviceInfo); Parameters: DeviceInfo Device info if read successfully, passed in the following structure: typedef struct rtxDevInfo { unsigned char MaxChannels; // Number of available channels in RX mode unsigned char Profile; // Profile in TX mode (not used) unsigned long ID; // ID in TX mode (not used) unsigned char Descriptor; // Descriptor in TX mode (not used) unsigned long SerialNumber; // Device serial number unsigned short SwRev; // Device software revision unsigned short HwRev; // Device hardware revision } rtxDevInfo; Return Value: Returns true if the requested information could be read successfully and false if accessing the hardware failed. 4.4 Configuration Functions 4.4.1 Configure BlueRobin RX mode operation In case the maximum possible number of channels is not required the number of channels to be used can be configured with this function to increase the system performance. Optionally this function can also be used to preset channels with profiles. There is no need to call this function if the maximum available number of channels has to be used without any preset. bool rtxConfig_RxMode(unsigned char MaxChannels, rtxPresetChannelProfile *ProfileList, unsigned char NoOfProfiles); Parameters: MaxChannels Number of required channels ProfileList Pointer to array of structures (ProfileList[NoOfProfiles]) containing channel and profile pairs to be preset; if no preset channels are required this parameter has to be set to NULL typedef struct rtxPresetChannelProfile { unsigned char Channels; // Number of channels to be preset with same profile unsigned char Profile; // Profile to be preset } rtxPresetChannelProfile; NoOfProfiles Number of channel and profile pairs contained in the array Return Value: Returns true if both setting number of channels and presetting channels was successful and false if configuring failed. Remarks: Reducing the number of used channels results in an increased system performance.$

  3DJHRI4.4.2 Set limit for consecutive lost data packets If an active channel does not get valid data packets over a certain period the synchronisation to the transmitter could get lost due to timing deviations. This function sets the number of consecutive lost data packets after which an active channel will be switched off or set to seach mode automatically. The default link failure limit is 8 packets, the valid range is 1 to 200 packets. bool rtxConfig_LinkFailureLimit(unsigned char Limit); Parameters: Limit Number of missed packets in a row causing a link failure Return Value: Returns true if the link failure limit could be changed and false if the change failed. Remarks: If the search timeout is set to 0 (see function rtxConfig_SearchTimeout()) a transmitter search will be started automatically if the link failure limit is reached. 4.4.3 Set timeout when trying to find a transmitter The time for trying to find a transmitter when starting a channel in both pairing and normal search mode can be set with this function. It is specified in seconds. If the transmitter could be found within this time the channel changes from search to active mode, otherwise it switches off. The default search timeout is 8 seconds, the valid range is 3 to 200 seconds. Setting the timeout value to 0 results in an infinite search and an automatic search start in case the link failure limit is reached. bool rtxConfig_SearchTimeout(unsigned char Timeout); Parameters: Timeout Number of seconds the search on a channel will be stopped if the specified transmitter could not be found or infinite search with automatic search start on link failure if timeout set to 0. Return Value: Returns true if the search timeout could be changed and false if the change failed. Remarks: In search mode the average current consumption is more than 200 times higher than in active mode, so if current consumption is an issue the search timeout should be set to the smallest value acceptable for the application. 4.4.4 Set receiver sensitivity for transmitter pairing mode This function has to be used to reduce the receiver sensitivity for a channel when pairing to a transmitter (ID set to 0) to be able to only get transmitters close to the receiver. As soon as a transmitter could be found the sensitivity of the corresponding channel will be set back automatically to its maximum value. Default setting is no sensitivity reduction, the valid reduction range is 0 to 40 dB. bool rtxConfig_PairingSensitivity(unsigned char Reduction); Parameters: Reduction Reduction of sensitivity in dB. Return Value: Returns true if the sensitivity reduction could be changed and false if the change failed. 4.4.5 Set ratio between active search time and search pause To reduce the average current consumption when searching for a transmitter the search can be paused in regular intervals. This function allows setting the search/pause ratio. Default ratio is 1, currently only a ratio of 0 for continuous search and 1 for a search/pause ratio of ~2/1 are supported. bool rtxConfig_SearchRatio(unsigned char Ratio); Parameters: Ratio Search/pause ratio, only 0 and 1 allowed. Return Value: Returns true if the search ratio could be changed and false if the change failed.

  3DJHRI4.5.8 Get state of RX channel To get the current state of a channel this function has to be used. bool rtxRX_ChannelGetState(unsigned char Channel, unsigned char &ChannelState, unsigned char &MessageState, unsigned char &DownloadState); Parameters: Channel Index of channel the state is required; starts at 0 ChannelState Channel state if reading was successful: rtxCH_STATE_OFF Channel switched off rtxCH_STATE_RESTART Channel restarted after high speed data download rtxCH_STATE_SEARCH Channel in search mode with specified ID rtxCH_STATE_PAIRING Channel in pairing mode, ID set to 0 rtxCH_STATE_ACTIVE Channel in active mode, no data or information available rtxCH_STATE_DATA Channel in active mode and new regular data or information received; can be read using rtxRX_GetData() rtxCH_STATE_DATA_MESSAGE Channel in active mode and new regular data and new message data received; can be read using rtxRX_GetData() and rtxRX_GetMessageData() MessageState Message state if reading was successful: rtxCH_STATE_MSG_IDLE No message pending rtxCH_STATE_MSG_PENDING Message sent, waiting for acknowledgement rtxCH_STATE_MSG_ACK Sent message acknowledged rtxCH_STATE_MSG_FAILED Sending message failed DownloadState Data download state if reading was successful: rtxCH_STATE_DOWNLOAD_IDLE No data download pending rtxCH_STATE_DOWNLOAD_PENDING Data download in progress, number of processed bytes can be read using rtxRX_GetDownload() rtxCH_STATE_DOWNLOAD_READY Requested data download received, can be read using rtxRX_GetDownload() rtxCH_STATE_DOWNLOAD_FAILED Data download failed Return Value: Returns true if the state of the channel could be determined and false if the function failed. 4.6 RX Message Functions 4.6.1 Send message on RX channel This function can be used to send a message including message info bytes to a transmitter after the next received data packet. bool rtxRX_ChannelSendMessage(unsigned char Channel, unsigned char Message, unsigned char *Data); Parameters: Channel Index of channel the message has to be sent on; starts at 0 Message Message identifier Data Pointer to 5 bytes containing message info Return Value: Returns true if the message for the channel could be prepared to be sent (but not already sent!) and false if the function failed. Remarks: Sending a message can also be requested if a channel is not already started, so e.g. a wake-up message could be sent to a transmitter immediately after the first standby packet has been received. The periodically called function rtxRX_GetState() signals any progress or failure in the message handling. Function rtxRX_ChannelGetState() can be used to get more details of the current message handling state.

  3DJHRI4.6.2 Send message data on RX channel This function can be used to send message data to a transmitter after the next received data packet. bool rtxRX_ChannelSendMessageData(unsigned char Channel, unsigned short Descriptor, unsigned char Size, unsigned char *Data); Parameters: Channel Index of channel the message data have to be sent on; starts at 0 Descriptor Data descriptor Size Number of data bytes to be sent; valid range is 1 to 48 Data Pointer to data to be sent Return Value: Returns true if the message data for the channel could be prepared to be sent (but not already sent!) and false if the function failed. Remarks: There is no built-in acknowledgement process for message data. If an acknowledgement is required it is recommended to read back and verify the sent data or any other indicator showing a successful transfer. 4.6.3 Request high speed data download on RX channel To send a request for a memory download to a transmitter after the next received data packet this function has to be used. All active channels will be switched off temporary during download and set to restart state (search after high speed data download) afterwards. bool rtxRX_ChannelRequestDownload(unsigned char Channel, unsigned char Flags, unsigned long Address, unsigned long Size); Parameters: Channel Index of channel the data download has to be requested; starts at 0 Flags Data download options (currently not used, to be set to 0) Address Start address for data to be downloaded Size Number of bytes to be downloaded Return Value: Returns true if the request for the channel could be prepared to be sent (but not already sent!) and false if the function failed. Remarks: The periodically called function rtxRX_GetState() signals any progress or failure in the data download handling. Function rtxRX_ChannelGetState() can be used to get more details of the current download state. 4.6.4 Clear any pending message and data download request on RX channel This function removes any pending message and data download request and clears all corresponding channel buffers. bool rtxRX_ChannelClear(unsigned char Channel); Parameters: Channel Index of channel to be cleared; starts at 0 Return Value: Returns true if the channel could be cleared and false if the function failed.

  3DJHRI4.7 RX Data Functions 4.7.1 Update internal buffers and return RX mode state The following function has to be called periodically with the update rate required by the application (typically one second). It parses all data automatically sent by the transceiver hardware from the USB port buffer to the DLL buffers and signals the availability of new data or information to the application. bool rtxRX_GetState(unsigned short &State); Parameters: State Current state if reading was successful, signaled with the following flags: rtxSTATE_RX_DATA New channel data or information received; for details see rtxRX_GetData() rtxSTATE_RX_MESSAGE Requested channel message data or information received; for details see rtxRX_GetMessageData() stxSTATE_RX_DOWNLOAD New channel data download or progress info received; for details see rtxRX_GetDownload() Return Value: Returns true if updating the buffers and the transceiver state was successful and false if accessing the hardware failed. Remarks: It is recommended to call this function at least every two seconds to avoid buffer overflows. 4.7.2 Get new data received on any RX channel This function has to be used to get received regular data on any channel together with signal strength and sequence counter. To pass new data a FIFO buffer is used. This buffer is big enough to store data for at least 3 seconds, so calling BR_GetState() to check for new data is required at least every 2 seconds to ensure no data will get lost. Also a lost packet, a lost transmitter, a not successful search and an automatic search start will be indicated. bool rtxRX_GetData(unsigned char &Channel, unsigned char &Type, unsigned char &SignalStrength, unsigned char &SequenceCounter, unsigned char *Data); Parameters: Channel Index of the channel the data have been received on; starts at 0 Type Type of data or information rtxCH_TYPE_DATA Data packet with 5 data bytes received rtxCH_TYPE_STANDBY Standby packet with one info byte received rtxCH_TYPE_DATA_LOST Data packet lost rtxCH_TYPE_TX_LOST Transmitter lost, channel switched off rtxCH_TYPE_TX_SEARCH Transmitter lost, new search started rtxCH_TYPE_SEARCH_STOPPED Search for transmitter not successful, channel switched off rtxCH_TYPE_STANDBY_SENT Transmitter successfully set to standby mode SignalStrength RSSI level of the received data SequenceCounter Sequence counter state when data have been received Data Pointer to received data bytes or standby info byte Return Value: Returns true if new data are available and false if no new data have been received. Remarks: It is recommended to call this function as many times as it returns true after rtxRX_GetState() indicates new data are available.

  3DJHRI4.7.3 Get requested message data received on any RX channel This function has to be used to get requested message data on any channel together with the signal strength. There is only one message data buffer per channel, so received data should be read before requesting further message data on a channel. Also indicates a failed message data request. bool rtxRX_GetMessageData(unsigned char &Channel, unsigned char &State; unsigned char &SignalStrength, unsigned char &Size, unsigned char *Data); Parameters: Channel Index of the channel the message data have been received on; starts at 0 State Message state: rtxCH_STATE_MSG_OFF Channel not in active mode, message will be sent as soon as channel is in active mode rtxCH_STATE_MSG_PENDING Message sent, waiting for acknowledgement rtxCH_STATE_MSG_ACK Sent message acknowledged rtxCH_STATE_MSG_FAILED Sending message failed SignalStrength RSSI level of the received message data, set to 0 if message data request failed Size Number of passed bytes Data Pointer to buffer for passing data; has to be big enough to receive the number of requested bytes (max. 48 bytes of message data are possible) Return Value: Returns true if new message data are available and false if no new message data have been received. Remarks: It is recommended to call this function as many times as it returns true after rtxRX_GetState() indicates new message data are available. To avoid a buffer overflow for “unexpected” pending messages it is recommended to always use a 48 byte buffer even if less bytes have been requested. 4.7.4 Get requested high speed data download received on any RX channel This function has to be used to get a requested data download on any channel. There is only one data download buffer for all channels, so received data should be read before requesting the next data download. bool rtxRX_GetDownload(unsigned char &Channel, unsigned char &State; unsigned char &SignalStrength, unsigned long &Address, unsigned long &Size, unsigned char *Data); Parameters: Channel Index of the channel the data download has been received on; starts at 0 State Data download state: rtxCH_STATE_DOWNLOAD_OFF Channel not in active mode, data download will be started as soon as channel is in active mode rtxCH_STATE_DOWNLOAD_PENDING Data download in progress; received bytes available in Size rtxCH_STATE_DOWNLOAD_READY Data download completed rtxCH_STATE_DOWNLOAD_FAILED Data download failed SignalStrength RSSI level of the received data download, set to 0 if data download failed Address Start address of downloaded data Size Number of already processed bytes; has to be set to application buffer size to allow buffer overflow check; max supported buffer size is 512kBytes Data Pointer to buffer for passing data; has to be big enough to receive the number of requested data bytes. Data will only be copied to buffer if download completed Return Value: Returns true if a new data download is available and false if no new data have been received. Remarks: This function is required to be called only once after rtxRX_GetState() indicates new data or information as not more than one data download can be processed at the same time.

$  3DJHRI5 Integration Steps 5.1 Initialization First of all the rtxBlueRobin DLL has to be initialized. Next steps are to scan for connected BlueRobin transceiver units or dongles, to get the USB device info of the device to be used, to open the port to that device and to initialize the device. Here is an example of how to search for and then initialize either a BM-USBRTX4 unit or if that one cannot be found a BM-USBD1 dongle: int FoundDevices; rtxUsbDeviceInfo UsbDeviceInfo; // BlueRobin DLL not already initialized? if (!rtxDll_IsInitialized()) { // Initializing DLL required before calling any further DLL function rtxDll_Initialize(); } // Check if BM-USBD1 or BM-USBRTX4 device connected rtxInterface_ScanForDevices(bmiDEVTYPE_USBRTX4, FoundDevices); // No BM-USBRTX4 connected? if (FoundDevices == 0) { rtxInterface_ScanForDevices(bmiDEVTYPE_USBD1, FoundDevices); } // Also no BM-USBD1 connected? if (FoundDevices == 0) { // No BlueRobin transceiver device found ... } // USB device info for first found device not available? if (!rtxInterface_GetInfo(0, &UsbDeviceInfo)) { // BlueRobin transceiver device info not found ... } // Port cannot be opened? if (!rtxDevice_Open(UsbDeviceInfo.PortName)) { rtxDevice_Close(); // Opening port for BlueRobin transceiver device failed ... } // Initializing transceiver to x channels failed? if (!rtxDevice_InitHardware(x)) { rtxDevice_Close(); // Could not initialize BlueRobin transceiver device ... } // Start unplugg detection of transceiver device rtxInterface_UnplugDetectionStart(UsbDeviceInfo.PortName); Next the device information can be read from the opened transceiver, channel profiles have to be set and further parameters affecting all channels can be set: rtxDevInfo DeviceInfo; rtxPresetChannelProfile ProfileList[1]; // Get device information rtxDevice_GetInfo(&DeviceInfo); SerialNumber = DeviceInfo.SerialNumber; SoftwareRevision = DeviceInfo.SwRev; HardwareRevision = DeviceInfo.HwRev; MaxChannels = DeviceInfo.MaxChannels; // Set number of required channels to 20 and preset 10 of them with profile 33 and 10 with profile 99 ProfileList[0].Channels = 10; ProfileList[0].Profile = 33; ProfileList[1].Channels = 10; ProfileList[1].Profile = 99; rtxConfig_RxMode(20, ProfileList, 2); // Infinite search on started channels rtxConfig_SearchTimeout(0); // Set number of lost packets in a row from a transmitter causing to search for it again to 6 rtxConfig_LinkFailureLimit(6);$

$  3DJHRIFor receiving a transmitter on a channel it is recommended to first reset the channel, to set its ID to the transceiver ID to be received if a specific transmitter has to be received and then to start the channel: // Channel to default settings rtxRX_ChannelReset(Channel); // Set transmitter ID to be received, not needed if any transmitter has to be received rtxRX_ChannelSetID(Channel, ID); // Start channel rtxRX_ChannelStart(Channel); To stop receiving a transmitter on a channel the channel just has to be stopped: // Stop channel rtxRX_ChannelStop(Channel); As soon as at least one channel has been started the state of the transceiver device should be checked periodically WORD wState; BYTE bChannel; BYTE bType; BYTE bSignalLevel; BYTE bSequenceCounter; BYTE bData[rtxMAX_MESSAGE_DATA_BYTES]; DWORD dwID; // Getting state successful? if (rtxRX_GetState(wState)) { // New data available? if ((wState & rtxSTATE_RX_DATA) > 0) { // Process all new regular data or information while (rtxRX_GetData(bChannel, bType, bSignalLevel, bSequenceCounter, bData)) { // Next action dependent on received data/information type switch (bType) { // Data received case rtxCH_TYPE_DATA: // First get current ID of channel if not already read if (...) { // Get ID of found device if (rtxRX_ChannelGetID(bChannel, dwID)) { // Store ID ... } } // Process received data ... break; // Data packet lost case rtxCH_TYPE_DATA_LOST: // Process packet lost information ... break; // Transmitter lost case rtxCH_TYPE_TX_LOST: // Does not happen when automatic search is set break; // Automatic search started again case rtxCH_TYPE_TX_SEARCH: // Process search start information ... } } } } else // Access to port failed { // Hardware error handling ... } When ending the application the opened port has to be closed and the rtxBlueRobin DLL has to be released: // DLL already initialized? if (rtxDll_IsInitialized()) { // Device already opened? if (rtxDevice_IsOpen()) { // Stop all channels rtxRX_ChannelStop(rtxALL_CHANNELS); // Close COM port rtxDevice_Close(); } // Unload DLL rtxDll_DeInitialize(); }$
