Sending sensor reading over BLE

Hi all,

I need your help in a little project im doing. I have connected a Force sensor (FlexiForce 45KG) to port A0 on my arduino nano 33 IOT and trying to send the readings from the sensor via BLE to an app I created with app inventor. when trying to use one of the sample codes in arduino (LED control button) my app detects arduino but when trying to write a code for my sensor the app cannot detect the arduino. can you help me with the code I need to write for it to work?

Replace the app with a standard BLE terminal and start again. That will give us a better idea of where the problem is.

Please post your code.

show your code please !!!
