Android Question Connect and manage a scp32 Via BLE

[MarcoLaudati]

I thank you for your help so far, this is the situation right now, I have the scp32 chip configured with the following services:


The control unit provides the tablet client with a single primary station service with uuid: 0000a002-0000-1000-8000-00805f9b34fb.
Below are summarized in a table the features present in the service:

etc ..


currently I have configured the code in this way:


ON STARTER

Sub Service_Create
            'This is the program entry point.
            'This is a good place for a single activity.
            Log ("Service Create Starter")
            CallSubDelayed (FirebaseMessaging, "SubscribeToTopics")

            'BLE
            manager.Initialize ( "manager")
            ServiceId = UUID ("0000a002")
            ReadChar = UUID ("1001")
            WriteChar = UUID ("1002")
            messagesToSend.Initialize
            Serial1.Initialize (115200)

End Sub

Sub Service_Start (StartingIntent As Intent)

End Sub

Sub Service_TaskRemoved
            'This event will be raised when the user removes the app from the recent apps list.
End Sub

Private Sub Manager_StateChanged (State As Int)
            If State <> manager.STATE_POWERED_ON Then
                        ToastMessageShow ("Please enable Bluetooth", True)
            else
                        StartScan
                      
            End If
End Sub

Public Sub StartScan
            If rp.Check (rp.PERMISSION_ACCESS_COARSE_LOCATION) Then
                        If manager.State = manager.STATE_POWERED_ON Then
'manager.Scan (Array (ServiceId))
                                    manager.Scan (Null)
                        End If
            End If
End Sub

Private Sub Manager_DeviceFound (Name As String, DeviceId As String, AdvertisingData As Map, RSSI As Double)
            Log ($ "DeviceFound: $ {Name}" $)
            Log ("Found: Name =" & Name & ", id =" & DeviceId & ", RSSI =" & RSSI & ", AdvertisingData =" & AdvertisingData) 'ignore
            manager.Connect2 (DeviceId, False)
            manager.StopScan
End Sub

Private Sub Manager_Connected (Services As List)
            Log ( "Connected")
            manager.SetNotify (ServiceId, ReadChar, True)
            connected = True
            CallSub2 (Main, "SetState", connected)
            messagesToSend.Clear
End Sub

ON MAIN

Public Sub SetState (connected As Boolean)

            If connected Then
                        ProgressDialogHide
            else
                        ProgressDialogShow2 ("Trying to connect", False)
            End If
End Sub

The startup application sees my chip with its MAc Adress, but remains in a connection waiting state, as you can see from my attachment.




if I try to connect with Nrf connect I connect and retrieve all the UUIDs present in the chip database correctly. Thank you in advance for your help.

It is a duty to thank all those who have helped to solve this problem.
And it is necessary to communicate that the problerma is solved. The reason the connection failed was that the chip was badly confugated.
Our work served to convince the chip technician that the problem was on his side.
Thank you all. The problem is solved
