I'm using a Arduino Uno + HC06 (Bluetooth module)
My project is now fishished and I'm able to communicate with my Arduino through an application developed on Android. Everything is working well :)
My only issue is... since the begegning of my project, I'm not able to send AT command to the HC06 to configure it :(
- My serial is working because tested with BT communication
- My HC06 is not connected (its led is blinking)
- all speeds 1200 to 115200. For BT communication, I discovered my HC06 is using 38400 Bauds by default.
- with and without CR LF
- Lower and Upper cases
The HC06 never answer to any AT commands and more... I read the HC06 led bliking duration can change when AT commands received but on my side, the blinking is regular and never change. Does it mean it never receives anything?
I'm lost but I don't want to keep the HC06 default name and PIN... :confused:
