Hi guys,
I'm using The Arduino Nano 33 BLE for a college project and was testing the connection between it and my phone.
I was running the SimpleAccelerometer sketch that came with the Nano 33 library to see if the data would show up on the app.
Everything worked perfectly last week when I tested it and life was good.
I finished off a few more parts of the project and came back around to work more on the software.
This is where disaster strikes, the Nano won't show up on the the app anymore so I can't connect at all.
I'm using the exact same Sketch I was previously and I've no idea what happened.
I read online that you need to the serial monitor to be open to connect but that had no effect.
I hope I'm doing something silly and it's an easy fix, my deadline is this weekend, if anyone can help me I'll be eternally grateful

The SimpleAccelerometer does not use BLE. It only prints data to the Serial Monitor window in the IDE.
To test BLE:
compile and download a BLE Peripheral example e.g.
File -> Examples -> ArduinoBLE -> Peripheral -> BatteryMonitor
open the Serial Monitor or comment the while (!Serial); source code line
make sure Bluetooth is enabled on your phone before you start the BLE app
try another generic BLE app e.g. BLE Scanner
Just to make sure, the Arduino Nano 33 BLE has a fragile PCB antenna. There should be 5 small SMD components on the green PCB part. These can be ripped off when the board is not handled with care. (Happend to myself).
If you have your own sketch, please post the code (use code tags).
