All E32-TTL-100 Datasheet V1.0 .1．Introduction E32-TTL-100 1.1 Feature E32-TTL-100 E32-TTL-100 is a wireless transceiver module with LoRa spread-spectrum technology, operates at 434MHz, based on original imported RFIC SX1278 from SEMTECH, transparent transmission is available, TTL level. The module adopts LoRa spread-spectrum technology, which means the transmitting distance is much longer than before. The advantages of this module is more concentrated power density and better anti-interference performance. The module features FEC （Forward Error Correction） algorithm, which ensure its high coding efficiency & good correction performance. In the case of sudden interference, it can correct the interfered data packets automatically, so that the reliability & transmission range are improved correspondingly. But without FEC, those date packets can only be dropped. The module has the function of data encryption & compression. The data of the module transmit in the air features randomness. And with the rigorous encryption & decryption, data interception becomes pointless. The function of data compression can decrease the transmission time & probability of being interference, while improving the reliability & transmission efficiency. 1.2 Basic usage E32-TTL-100 No. Usage Description 1 Transparent transmission Default Module A transmits 01 02 03 to module B, then module B receives 01 02 03. 2 Fixed transmission Module can communicate with other modules in different channels, easy for networking and repeater. Module A transmits AA BB CC to module B (address: 0x00 01, channel: 0x80), HEX format is 00 01 80 AA BB CC (00 01 refers to the address of module B, 80 refers to the channel of module B), then module B receives AA BB CC (only module B). 3 Broadcast transmission Set the module address as 0xFFFF, then the module can communicate with other modules in same channel. 4 Power-saving In power-saving mode, the module’s maximum receiving response time is 2000ms, which the average current is below 50uA. 5 Sleep When the module works in sleep mode, transmitting & receiving is not available, while the configuration is available. The typical current is 2.0uA in this mode. See more details in related manual about fixed transmission and broadcast transmission.

All 2.2 Connect to MCU E32-TTL-100 No. Description（STM8L MCU） 1 The UART module is TTL level. 2 For some MCU works at 5VDC, it may need to add 4-10K pull-up resistor for the TXD & AUX pin. 2.3 Reset E32-TTL-100 No. Description 1 When the module is powered, AUX outputs low level immediately, conducts hardware self-check and set the operating mode on the basis of the user parameters. During the process, the AUX keeps low level. After the process completes, the AUX outputs high level and starts to work as per the operating mode combined by M1 and A0. Therefore, the user needs to wait the AUX rising edge as the starting point of module’s normal work. 2.4 AUX description E32-TTL-100 AUX Pin can be used as indication for wireless send & receive buffer and self-check. It can indicate whether there are data that are yet to send through wireless, or whether all wireless data has sent through UART, or whether the module is still in the process of self-check initialization.

All 2 【Indication of wireless transmitting】 Buffer (empty): the internal 512 bytes data in the buffer are written to the RFIC (Auto subpackage). When AUX=1, the user can input data less than 512 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 512 bytes data in the buffer have not written to the RFIC completely. If the user starts to transmit data at this circumstance, it may cause overtime when the module is waiting for the user date, or transmitting wireless subpackage. Notes: When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the last packet of data is still in transmission. 3 【Configuration procedure of module】 Only happened in the process of power-on and exit sleep mode. No. Notes for AUX 1 For function 1 & function 2 mentioned above, the priority should be given to the one with low level output, which means if it meets each of any low level output condition, AUX outputs low level, if none of the low level condition is meet, AUX outputs high level. 2 When AUX outputs low level, it means the module is busy & cannot conduct operating mode checking. After AUX outputs high level 1ms later, it will complete the mode-switch task. 3 After switching to new operating mode, it won’t be work in the new mode immediately until AUX rising edge 2ms later. If AUX is on the high level, the operating mode switch can be effect immediately. 4 When the user switches to other operating modes from mode 3 (sleep mode) or it’s still in reset process, the module will reset user parameters, during which AUX outputs low level.

All .3．Operating mode E32-TTL-100 Contents in below table are the introduction of input status of M1 & M0 and their corresponding mode:  Mode（0-3） M1 M0 Mode introduction Remark Mode 0 Normal 0 0 UART and wireless channel is opened, transparent transmission is on. The receiver must works in mode 0 or mode 1 Mode 1 Wake-up 0 1 UART and wireless channel is opened. The difference between normal mode and wake-up mode is it will add preamble code automatically before data packet transmission so that it can awaken the receiver works in mode 2. The receiver can works in mode 0, mode 1 or mode 2. Mode 2 Power-saving 1 0 UART is disabled. Wireless module works at WOR mode (wake on radio). It will open the UART and transmit data after receive the wireless data. 1,the transmitter must works in mode 1 2,transmitting is not allowed in this mode Mode 3 Sleep 1 1 Parameter setting. 3.1 Mode switch E32-TTL-100 No. Remarks 1 The user can decide the operating mode by the combination of M1 and M0. The two GPIO of MCU can be used to control the mode-switch. After modifying M1 or M0, it will start to work in new mode 1 ms later if the module is free. If there are any serial data that is yet to finish wireless transmitting, it will start to work in new mode after the UART transmitting finishing. After the module receives the wireless data & transmits the data through serial port, it will start to work in new mode after the transmitting finishing. Therefore, the mode-switch is only workable when AUX outputs 1, otherwise it will delay. 2 For example, in mode 0 or mode 1, if the user inputs massive data consecutively and switches operating mode at the same time, the mode-switch operation is invalid. New mode checking can only be started after all the user’s data process completing. It is recommended that after check AUX pinout status and wait 2ms after AUX outputs high level, then switch the mode. 3 If the module switches from other modes to stand-by mode, it will be work in stand-by mode only after all the remained data process completing. The feature can be used to save power consumption. For example, the transmitter works in mode 0, after the external MCU transmits data “12345”. It can switch to sleep mode immediately but not wait the rising edge of the AUX pin, also the user’s main MCU will go dormancy immediately. Then the module will transmit all the data through wireless transmission & go dormancy 1ms later automatically. Which reduce MCU working time & save power. 4 Likewise, this feature can be used in any mode-switch. The module will start to work in new mode within 1ms after completing present mode task, which enable the user to omit the procedure of AUX inquiry and switch mode swiftly. For example, when switch from transmitting mode to receiving mode, the user MCU can go dormancy in advance of mode-switch, using external interrupt function to get AUX change so that the mode-switch can be done. 5 This operation is very flexible and efficient. It is totally designed on the basis of the user MCU’s convenience, at the same time reduce the whole system work load as much as possible, increase the efficiency of system work and reduce power consumption.

All 3.2 Normal mode（Mode 0） E32-TTL-100 When M1 = 0 & M0 = 0, module works in mode 0 Transmitting The module can receive the user data from serial port, and transmit wireless data package which length is 58 bytes. When the data inputted by user is up to 58 byte, the module will start wireless transmission. During which the user can input data continuously for transmission. When the required transmission bytes is less than 58 byte, the module will wait 3-byte time and treat it as data termination unless continuous data inputted by user. Then the module will transmit all the data through wireless channel. When the module receives the first data packet from user, the AUX outputs low level. After the module transmit all the data into RF chip & start transmission, AUX outputs high level. At this time, it means that the last wireless data package transmission has started, which enable the user to input another 512 bytes continuously. The data package transmitted from the module works in mode 0 can only be received by the module works in mode 0 or 1. Receiving The module keeps the wireless receive function on, it can receive the data packet transmitted from the module works in mode 0 & mode 1. After receiving the data packet, the AUX outputs low level, 5ms later the module starts to transmit wireless data through serial port TXD pin. After all the wireless data have been transmitted via serial port, the module AUX outputs high level. 3.3 Wake-up mode（Mode 1） E32-TTL-100 When M1 = 0 & M0 = 1, module works in mode 1. Transmitting The condition of data packet transmission & AUX function is the same as mode 0. The only difference is that the module will add preamble code before each data packet automatically. The preamble code length depends on the wake-up time set in the user parameters. The purpose of the preamble code is waking up the receiving module works in mode 2. Therefore, the data package transmitted from mode 1 can be received by mode 0, mode1 and mode 2. Receiving The same as that in mode 0. 3.4 Power-saving mode（Mode 2） E32-TTL-100 When M1 = 1 & M0 = 0, module works in mode 2. Transmitting UART is closed, the module cannot receive any serial port data from outside MCU. Hence the module works in this mode does not have the function of wireless transmission. Receiving In mode 2, it is required the date transmitter works in mode 1. The wireless module monitors the preamble code at regular time. Once it gets the preamble code, it will remain as receive status and wait for the completion of the entire valid date package receives. Then the module lets the AUX outputs low level, 5ms later opens the serial port to transmit received wireless data through TXD. Finally AUX outputs high level after process completing.

All The wireless module stays in “power-saving – monitoring” working status (polling). By setting different wake-up time, the module can have different receive response delay (2s maximum) and average power consumption (30uA minimum). The user needs to achieve a balance between communication delay time & average power consumption. 3.5 Sleep mode (Mode 3） E32-TTL-100 When M1=1,M0=1,module works in mode 3 Transmitting N/A Receiving N/A Parameter setting This mode can be used for parameter setting. It uses serial port 9600 & 8N1 to set module working parameters through specific instruction format. (pls refer to parameters setting for details) Notes When the mode changes from stand-by mode to others, the module will reset its parameters, during which the AUX keeps low level and then outputs high level after reset completing. It is recommended to check the AUX rising edge for user. 3.6 Quick communication test E32-TTL-100 Steps Operation 1 Plug the USB test board (E15-USB-T2) into computer, make sure the driver is installed correctly.
