I got a new Bluetooth serial board that i use with my Arduino Uno: http://wiki.seeed.cc/Grove-Serial_Bluetooth_v3.0/
and i found out that MOST commands on this page are responding when i send them from my serial command line: https://seeeddoc.github.io/Bluetooth_Bee_v2.0/
For example AT+ROLEM returns Set:M
AT+VERSION returns VERSION:HMSoft V621
But i cannot connect the BT board in master mode with any bluetooth device in slave mode (BT speaker for example).
According to the page i just give above, i should enter : AT+LNKxxxxxxxxxxxx where the code after LNK is the mac address of the BT device i want to connect to. But this command does not return anything :confused:
I also tried AT+CONxxxxxxxxxxxx but it does not return anything
I see many different commands on internet to accomplish this, but none of them work.
I know my BT device works because i can connect to it with my phone. There is no pin code.
Maybe i have to send specific commands ?
thanks for your help,
