Did you get this working?
I’m having trouble just writing the AT-commands to the Bluetooth module. I can write them just fine, I just get some very strange output back. After having send a couple of commands, they just start being returned.
If i send ‘\r\n+STWMOD=0\r\n’ I get some gibberish back. Then, I try sending it again, which returns gibberish + ‘+STWMOD=0\r\n’. Then i try sending the same command again i get something like gibberish + ‘+STWMOD=0\r\n+STWMOD=0\r\n’. If i try again, i get an even longer reply. I’m wondering if anyone else has experiences this, and know how to fix it?
My current course of action is trying to scale the Uart signal from 5 to 3.3, to better suite the Bluetooth circuit. But to the best of my knowledge that shouldn’t really do much.
Damn, this is causing me a lot more trouble than i would have thought.
