Sleep Mode: A HI state on the SLEEP pin will put the module into this mode, where the processor in the module is in low power sleep mode. In this mode, the module cannot communicate with the Host via UART communication. However, Bluetooth can be kept on and connected in this mode to listen for any incoming data packets. The module will only be waken by a LO enable signal on the SLEEP pin . B. On Mode: A LO state on the SLEEP pin will put the module into this mode. In this mode, the processor in the module is awake and ready to communicate with the Host via UART communication. UART communication is possible for all AT command operations. Once SLEEP pin is set back to HI, the module will enter into Sleep Mode. C. Test Mode: This mode is used for RF testing purposes only. By sending an AT command from HOST to module (making sure that the SLEEP pin is set to LO first), the module will start RF Test mode. By sending different test data to the SDT, the HOST can control the module to transmit on different frequencies, in two different transmission modes : unmodulated carrier or modulated carrier with test data pattern alternating 1s and 0s. 2. HOST Interface specification 2.1 Overview UART interface is used for data transfer between host and SDT module. The HOST system can send command/data or receive event information/data via UART interface. 2.2 Connection with HOST systems Connection with HOST system consist of the UART interface and 3 control pins. The below is a reference diagram for the connection of the CMM-9301-SDTV2 module with an external host processor: The 3 control pins have the following functionality.

CMM-9301-SDT Bluetooth Low Energy Serial Data Bridge Module SPEC No. CMM-9301-SDT BLE Bridge module Revision 2.0 State 2015-03-04C-MAX printed 2015-03-04 Version English Page 5 of 16 C-MAX LINK: This pin indicates to HOST system the Bluetooth connectivity state of the SDT module. LINK signal will be asserted to LOW at power up and in the event of Bluetooth disconnected. During Bluetooth connected phase, LINK signal will be stay HIGH. SLEEP: Control signal by HOST to wake module and start UART communication. It has to be asserted Low before start serial communication. Asserting this pin back to High will put module into low power sleep mode. Note that this pin does not control the Bluetooth connectivity. Bluetooth connectivity has to be controlled via AT commands. IRQ: IRQ indicates Bluetooth Data Received status from SDT module to HOST system. Regardless of SLEEP pin status, when Bluetooth is turned on, once Bluetooth data is received, module will assert IRQ signal to High . Hereafter, upon more received data packet (up to a maximum buffer of 64 packets @ 20 bytes each), IRQ will be kept High until the received packet buffer is all cleared or if received packets >= 64 packets, then IRQ will be asserted Low to indicate an empty buffer. Behavior of each pins are described below. Default status of LINK and IRQ signal is Low. Host upon initialisation: 1. Set UART_EN = VDD 2. Power up module by applying power to VDD 3. Bluetooth is turned on automatically 4. If no data is expected to be transferred via Bluetooth, Bluetooth can be turned off by first asserting SLEEP signal to Lo (to wake up module ready for UART communication), then issue AT Command : AT+BTOFF. 5. To save power, keep SLEEP signal at High state when there is no UART communication. For host to send data over Bluetooth: 1. HOST system assert SLEEP signal to Low (to wake up module ready for UART communication) 2. Issue AT command AT+BTON 3. Wait for peer device to connect to module. Once Bluetooth link with peer device is established, SDT module asserts LINK signal to HIGH. 4. Send data by issuing AT Command AT+WRITEDATA = <Param>. 5. To disconnect Bluetooth, issue AT command : AT+BTDISCON, This will put module into discoverable and connectable mode.

To turn off Bluetooth completely, issue AT command AT+BTOFF 7. HOST system asserts SLEEP signal to HIGH after finishing UART communication For host to receive data from peer device via Bluetooth: 1. Assert SLEEP signal to Low (to wake up module ready for UART communication) 2. Issue AT command AT+BTON 3. Wait for peer device to connect to module. Once Bluetooth link with peer device is established, SDT module asserts LINK signal to HIGH 4. When data is received via Bluetooth, SDT module asserts IRQ signal to HIGH 5. HOST system detects IRQ 6. Issue AT command AT+READDATA? to read received data stored in buffer 7. To keep module in connected mode, just put module into low power mode by asserting SLEEP signal to HIGH 8. To disconnect from Bluetooth but to remain discoverable and connectable, issue AT command : AT+BTDISCON, then put module into low power mode by asserting SLEEP signal to HIGH 9. To turn off Bluetooth completely, issue AT command AT+BTOFF 10. Assert SLEEP signal to HIGH after finishing UART communication
