I have the above board and connected it to my PC. I am using TeraTerm to talk to it via UART. I need to use a Classic Bluetooth Serial Connection.
I cannot seem to be able to successfully issue many AT commands. and the following shows what I mean:
ready
AT
OK
AT+RST
OK
ready
AT+GMR
AT version:1.1.b1.0(14be84b - Feb 8 2018 08:01:18)
SDK version:v3.0-rc1-161-g8856cc0
compile time:Mar 16 2018 04:54:52
AT+CMD?
ERR CODE:0x01090000
ERROR
AT+BTINIT?
ERR CODE:0x01090000
ERROR
Anyone got any ideas?
