Hello, I wrote an AI2 program with a BLE function last year. It worked correctly before. However,
when I try to run this program recently, it always shows the following error message:
" invoke: no method named `StartScanning’ in class java.lang.Boolean"
Does anybody know what’s happened and how to solve this problem? Attached please find my files of error message and original program.
The blocks look okay to me.
Is this a new device with a higher level Andoid O/S ?
Maybe it's a permission issue?
Maybe need to start gps to begin scanning
Or permission
Good luck
