Hopefully one of you can help me. I've got a new Arduino 33 BLE and I'm trying to get it's bluetooth peripheral functions to work. I've tried every example in the Custom Example Library but I can't get it to advertise properly.
The advertise() function returns a 1 for succes the peripheral doesn't show up on my phone and my computer.
You will not see the Arduino in your Settings -> Bluetooth. That is OK.
That page is for pairing Bluetooth devices to your phone. The Arduino uses BLE where pairing is an optional security feature. Because it is optional and not needed, I do not believe the pairing functionality is even available in the library.
You can just connect to the Arduino inside the app. I use BLE Scanner on an iPhone and it works quite well. You can explore the GATT and read and write values. There are many other app available, but on iPhone I found the BLE Scanner to be the easiest to use.
