Hi guys,

I'm trying to read enviroment data from a module called thingy52,
the log below mean the module is not sending any data

Found: AntuTech, FF:B0:19:AF:F0:9F, RSSI = -45, (MyMap) {1=[B@42a20ab8, 6=[B@42a20b20, 8=[B@42a20b70, -1=[B@42a20bb8, 0=[B@42a20660}
Este = 1: 06
Este = 6: 420074A9FF52109B3349359B000168EF
Este = 8: 416E747554656368
Este = -1: 5900623EC2FA
Este = 0: 0201061106420074A9FF52109B3349359B000168EF0908416E74755465636807FF5900623EC2FA0000000000000000000000000000000000000000000000

I think because I have to active the notify in the module, I tried this:

B4X:
Public Sub writeData1
    manager.SetNotify("EF680200-9B35-4933-9B10-52FFA9740042","EF680201-9B35-4933-9B10-52FFA9740042",True)
    Log("Set Notify")
End Sub

Sub Manager_DataAvailable (ServiceId As String, Characteristics As Map)
    CallSub3(Main, "DataAvailable", ServiceId, Characteristics)
    Dim bc As ByteConverter
    Dim KeyCode As String
   
    Dim bc As ByteConverter
    For Each key As String In Characteristics.Keys
        Dim b() As Byte = Characteristics.Get(key)
        Log("Key: " & key &", value: " & bc.HexFromBytes(b))
        'Log(BytesToString(b, 0, b.Length, "utf8") 'useful if the data is actually a string
        If key = "" Then
        End If    
    Next

'    https://nordicsemiconductor.github.io/Nordic-Thingy52-FW/documentation/firmware_architecture.html#fw_arch_ble_services
'    Environment Service:

'    Humidity characteristic: EF680203-9B35-4933-9B10-52FFA9740042
   
End Sub

I got this error: "Caused by: java.lang.RuntimeException: Service not found"
line 79 is: manager.SetNotify("EF680200-9B35-4933-9B10-52FFA9740042","EF680201-9B35-4933-9B10-52FFA9740042",True)
