Hi everyone,
I hope this is the right place for this problem!
I recently bought a blueduino rev2 and I tried to pair it with my Raspberry Pi 3.
I do find the Blueduino in the bluetooth device list of the raspberry but when I try to pair it, it tells me that the authentication has failed:
Pairing failed -
GDBus.Error.org.bluez.Error.AuthenticationFailed:
Authentication Failed
In order to solve that problem, I wanted to change the auth mode. I know that by default it should be "no auth and passcode needed" but I don't know what is the problem with the connection to the Raspberry Pi in this case.
Anyway, since I don't have a USB to UART converter, I modified my Arduino Uno to transform it into a USB to UART converter.
Here are the connection I made:
I uploaded this code to the Blueduino:
void setup() {}
void draw() {}
I then used Termite (also tried with the arduino IDE) to communicate to the Blueduino:
- I'm sure I'm using the right COM port since I just have my arduino connected to the computer.
- I tried all the baud rates.
When I try sending AT, I got no respond at all.
Someone has any idea on what I am doing wrong? Either for the AT command or the reason why I can't pair the devices?
Thank you in advance!
