Arduino Mega + HC-06 bluetooth

Projects Networking, Protocols, and Devices

Hi,
I'm trying to connect my Android phone with my Arduino using an HC-06.
I have a voltage devider on my HC-06 Rx pin - so there shouldn't be any dangerous voltages for my HC-06.

But I couldn't get it up and running properly.
When I connect my Android device (running Serial Bluetooth Terminal from Kai Morich: ) the HC-06 LED stops blinking permanently.
But I couldn't get any data transfered:

My HC-06 is connected to serial 2.
It looks like an inappropriate baudrate....but I'm wasting my time - no progress since hours :frowning:
Any ideas?

It's just a bare Arduino Mega connected to my HC-06 - nothing else.

Just after I posted this I found one issue: there's Serial1.read.... but Serial1 is not connected. Changed it to Serial2 and now I can send input from my Android device to the Arduino IDE's serial monitor - ubt I cannot send data from Android to serial monitor:

Also I couldn't get any AT response. Neither from bluetooth terminal nor from serial monitor.

Damn....works well now. Jumpercable slipped off. Sometimes it's the small things :wink:
