Im working on a robot that will be controlled with a bluetooth connection. I just started the project and I had never used bluetooth modules before. I researched online and found some tutorials… I proceded to connect the module and write the code, and then when I upload it the BT Module blinks really fast (3 times per second approximately) and in the serial monitor (in NL & CR) when I write AT or any command I don’t get any response…
I tried changing the speed both on the serial monitor and on the code itself but I still wasn’t getting any responses from the module, just in some special cases I got corrupted responses with symbols, Xes, and �.
This is the code:
First post btw.
