I am new to Arduino. I need to use my Arduino nano 33 BLE sense as a classic Bluetooth, not BLE. According to the product page, this should be possible. However, I am stuck. I can only find libraries and codes to use it as a BLE device. Can anyone help?
IF the BLE is backwards compatible, it should do that automatically. I believe the only thing you have to do is ensure that it is in SPP mode and thus you are not trying to make the BT2 device perform like BLE. You may find some info on the Martyn Currey website.
