Receiving data from arduino into App inventor using HM-10 bluetooth module

[PolarPacific]

I have gotten my arduino to respond to the commands that turn the light blub on and off but I cant seem to send data from the arduino to the MIT inventor app. These are my screenshots of my code. Im pretty lost on what I'm missing to get this to work.

Im trying to send the number 2222 to the MIT app inventor app and have that number displayed in a text box.

Here you can get some ideas.

HM-10. BLE. Arduino UNO. Notify. Bluetooth. AT. iBeacon. Arrhythmia

Hello friends, I bought a wonderful HM-10 module with BLE for only $ 2. I have written my experiences on this Spanish website (http://kio4.com/arduino/161_HM10_BLE.htm) and I would like to share a summary in this Community. I have used the BluetoothLE 20190701 extension. I have connected the module to an Arduino UNO [hc10_3] I tried to use these libraries, but they did not work for me in Arduino UNO. CurieBLE.h is for Arduino 101 (Curie). ArduinoBLE is for Arduino MKR WiFi 1010,…

For BLE, it is typical to Register for Strings.
