I used an app to find the ip address of my bluetooth headphones then I connected my bluetooth module to my Arduino Elegoo Uno R3. When I meant into AT command mode and set my CMODE to 0 and and typed AT+BIND="the ip address of the headphone". I tried it a couple times but I kept getting an error. Can anyone please help me with this. Is there another way to make sure my bluetooth module always connects to my headphone.
