Hi,I have the cc2541 and I tried to follow the steps but for some reson it didn't work and now the module is not responding, the led always on (low light) and it not respond to AT commands as it did before.I tried reset with the PIO0 pin, didn't help.. Any idea?
Me too, only low led ON without any response, I don't know if because I used arduino pins without logic converter? Or something else?Is there is a way to know if it is firmware problem or hardware problem?
Is anyone have made this trick work with an arduino nano ?thanks
I have an AT-09 (HM-10 copy..) that shows up as name BT05.I can connect with my iPhone app "Bluetooth Serial" and comm via terminal, so i know it works.I have identified it as AT-09 through this website: http://www.martyncurrey.com/bluetooth-modules/There is no joy with this thing. Seems it can not be flashed.It has never responded to AT commands. This thing is a piece of junk.Does anyone know how to buy HM-10 direct from manufacturer?Thanks,Quint
