Please help to provide an example of coding in B4A related to my problem, I'm trying to display analog data from a potentiometer that I connect to the arduino analog port to B4A. Previously for data transmission from Arduino to B4A I used the HC-05 bluetooth module, when using HC-05 for communication to B4A I used the serial library on B4A and the communication was successful (data can be displayed to B4A). But when I replaced the Bluetooth module using AT-09 / HM-10, for communication to B4A I used the BLE2 library, the AT-09 / HM-10 module was successfully identified and successfully connected to B4A, but the data was not successfully displayed to B4A.
