I watched this video for HM-10 that shows pairing master/slave with two BLE modules:
I have two problems:
HM-11 BLE BEE in Uartsbee (V4 and V5) does not respond to any AT commands (AT should return OK at 9600baud rate). Uartsbee is connected to PC and I have console open. When switching from HM-11 to Meshbee, setting 115200baud and issuing +++ returns answer to the console. So the problem is that BLE BEE is not responding. PWR led on Uartsbee is steadily on. LED with name ‘ON’ is blinking on Uartsbee.
I have two XADOW BLE modules with two mainboards. In slave mode they work ok. I can receive and send data to Android tablet with BLE. Now I turn off BLE on Android and want to connect two Xadow BLE to each other. AT+ROLE0 returns OK+SET0. AT+ROLE1 on other device returns OK+SET1. According to the Youtube video, it should now return also OK+CONN. But this never happens.
I bought it like 6 months ago and still cannot solve this …tried also other AT commands from data sheet such as AT+DISC? for discovery. But your demo source code does not work for me: seeedstudio.com/wiki/Xadow_-_BLE …only AT+ROLE command works, but it’s not pairing with the master.
Please help, I’m lost
