Bluetooth not working

Question

Bluetooth not working

Closed this issue 4 years ago · 4 comments

Hi. Thank you for your project. I can successfully predict the characters using usb. But I can't seem to get any data from the Bluetooth module. Is there any way to check if the Bluetooth module is sending data to the pc? There is no output in the serial monitor when I try Bluetooth mode. Any thoughts?

Hi,
The first thing you should do is to check out if you see any output using the arduino ide serial monitor using the bluetooth serial port

Hey,
Thank you for your response. So in the ide I must change from the Arduino port to the receiving port of Bluetooth right? Then if I don't get any output on serial monitor it's a faulty Bluetooth module?

You're welcome. Not necessarily, it could also be related to a wrong connection

Thank you I'm able to get the Bluetooth working also. But it seems like I must keep uploading the Arduino code to the pro micro every time I plug it in again. If I don't upload the sketch, it keeps predicting d for every movement. How can I make the code stay on the board?
