Android Question Struggling to understand BLE2.

Members ReadData2 and WriteData require Service and Characteristic strings but I don't understand what they are and whatever I try seems to cause a syntax error.

My inability to understand this is frustrating. Have read and re read https://atadiat.com/en/e-bluetooth-low-energy-ble-101-tutorial-intensive-introduction/ a few times but still none the wiser.

Normally I can figure out something eventually if I have some working code to unpick. The BLEExample establishes a connection but it is not clear how to actually send and receive data other than details of the module. With RS232 I get an interrupt and go to retrieve the data. Is there a comparable event with BLE ?

With the module configured to be “uart transparent” The read data button reports Microchip, RN487x, 0000, 5505 102_BLDK3, 01040101, 1.18. Do one of these represent the service or the characteristic ? Plainly Microchip is the manufacturer, RN487x the model and 1.18 the version.

In an attempt to achieve something I note BLE2 has a member ReadRemoteRssi but how do I access the Rssi

adding

B4X:

Private Sub Butrssi_Click
    manager.ReadRemoteRssi
    Log("RSSI")
End Sub

Sub RssiAvilible(Succsess As Boolean,Rssi As Double)
    If Succsess=True Then Log("sucsess")
    Log(Rssi)
End Sub

Reports that RssiAvialable is not used

To get data transferred is it just a case of calling ReadData and WriteData and then retrieve the data from a DataAvialable event ?

Please someone must have a simple working example
