4 Function Description 4.1 Role description The module supports three roles: master, slave, and observer. The host supports connecting to other Bluetooth products of our company. When the module is used as a master, up to 2 slaves can be connected. Support transparent advertising and format transmission. auto connect. The module slave can connect with other models of our company's Bluetooth products to support transparent transmission.
4.1.3 Observer 1. Command AT+ROLE=2 to select the observation mode (valid after restart) 2. After receiving the advertising, print out all the contents of the advertising package through the serial port. 3. The observer device cannot be connected to any device. Check format below LEN MAC RSSI Advdata 1 byte 6 byte 1 byte No more than 31 byte Note: LEN is the sum of MAC, RSSI, and advertising data length. 1. The scan window and scan gap are consistent with the scan parameters. 2.
4.3.2 Format transmission The so-called format transmission refers to: the data sent to the module through the serial port and the data through the serial port of the module must conform to the defined format for transmission. The serial port sends "AT+TRANMD=0" to the device to switch the device to format transmission. The data format is as Slave No. Valid data 1byte Max:243bytes 0~1 Slave number: 0~1 is the target device number.

Configure it according to AT command. 6.1.2 Configuration over air Only for module that works as a slave. Open app “nRF connect”, start scanning，find “E104-BT52” and connect to it. nRF connect scanning list Open uuid-fff0 service，Enable configuration channel: notify; Copyright ©2012–2020，Chengdu Ebyte Electronic Technology Co.
nRF connect、Enable configuration channel: notify Send authenticate command（at+auth=12345），module returns “0x2befeb0d0a” means success； Over air configuration authentication Configure module according to 0 command table. 6.2 Data transmission For data transmission related instructions, see 5.3 Data Transmission Mode. Test Conditions: Configure one module as the master and one as the slave as described in the quick use guide for AT command list configuration mode; Software: AccessPort.
Other parameters are the default configuration. 6.2.1 Data transparent transmission 1. Power on the module. Enable logmsg printing for master and slave (at+logmsg=1); 2. Set the module to transparent transmission mode (AT+TRANMD=1). 3. After the host is successfully connected, it will print "sta: connecte 0 616263646564"; the slave will print sta: connecte 0 616263646566". The LINK pin is high.
The master sends transparent data 6.2.2 Format transmission 1. Same as Step 1 of 7.2.1 Data Transparent Transmission; 2. Set to format transmission (default format transmission, set command "AT+TRANMD=0") 3. Same as Step 3 of 7.2.1 Data Transparent Transmission; 4. The effective data sent by the master to the slave is "123456789" (ASCII). The format transmission data is packed "00 30 31 32 33 34 35 36 37 38 39" (HEX).
