I want to establish one way communication between my arduino and my ESP32 through bluetooth, but for some reason I can't figure out how to configure the BlueSMiRF correctly. The ESP32 code is just a simple BluetoothSerial code that's supposed to listen to any incoming connection and print incoming data to the console.
On the Arduino, I have executed the following commands:
SP,1234 I,5 (this found FCF5C408662A,ESP32,2C110) C,FCF5C408662A
After that the SMiRF prints 'TRYING', and after around 20 seconds it say 'CONNECT failed.' The Arduino code is just the CMD mode passthrough program I found on the internet.
I think there's something wrong with pairing on the SMiRF, because I can't connect it to my phone, or my PC either. I've done multiple factory resets with SF,1 but I still can't get it to work properly.
Can someone help me figure this out?
