Unable to Receive Data from App on Arduino Nano BLE Rev2

Hi everyone,

I'm encountering an issue where my app cannot send data to my Arduino Nano BLE Rev2. I have confirmed that the connection between the devices is established; however, despite trying several different methods, the Arduino still does not receive any data from the app.

Has anyone experienced a similar issue or have any suggestions on troubleshooting this problem? Any help would be greatly appreciated!

Thanks in advance.
