#4 HLK BLE 5.0 -How To Transmit DHT11 Data to Masters

This video is on PAIRING 2 HLK B50 BT Modules and sending DHT11 data from SLAVE (PERIPHERAL) to OLED at Master(Central).

AT+BTMODE=2 is to set slave to BLE only mode.

Pairing can be done either by using Name of the Slave or by MAC address of slave.
For this AT+SCANMODE =1 is used, which is for pairing using Name.
AT+PEERNAME=slave_name is the command to pair.
Only Master module can initiate pairing.
AT+ROLE=2 makes the module Master.
slave can advertise to multiple Masters in BLE mode
