i attached my ino file. its a simple program that accepts bluetooth chars from the nrf toolbox app to spin the motor. but the two functions BLEsetup() and aci_loop() are not declared.

im guessing this is a library issue? but i double checked my code and it looks like i imported all the libraries correctly. i downloaded stble.zip and added it to the library.

sorry am new to this. appreciate your help in advance!

What .h files are you importing into the file?
