Arduino Nano 33 BLE Sense Not Showing Up by Name During Bluetooth Scanning

I am working on a fall detection system using the Arduino Nano 33 BLE Sense Rev 2 board. The goal is to detect falls using data from the BMI270 sensor, send a Bluetooth signal to a mobile app, and trigger an SMS to a caretaker when a fall is detected. The issue I’m encountering is that when I try to scan for Bluetooth devices my Arduino device does not show up with the name I set in the code ("Fall_Detecter"). Instead, a list of device addresses appears, but none seem to be the Arduino Nano 33 BLE. Any help or suggestions would be much appreciated. Thanks in advance.

You need an impartial third party app like nrfConnect to verify if you actually have anything to connect to.

in nrfConnect Fall_Detecter is showing. but it is not connecting..

And also now fall detecter is showing in the app too but not connecting.

That's progress.

You'll need more of a BLE expert than me to delve into your Nano 33 code for why it won't Connect.
