Android Question read data from BLE

[tonga]

Hi all,

I'm just started with BLE. I need to read the values inside the Characteristics (byte, char, int... ) that a microprocessor+BLE send to my tablet and that I see. I'm using "BLE_Example".
Someone can help me?

Thanks!

What is the problem?

Are you able to connect to the BLE peripheral?
Can you post the relevant code and logs?

Hi,
the connection to peripheral is ok and the code is praticallythecode of BLE_Example. I append the picture of tablet during the execution. The data that I wish to extract are in the Characteristics XXXX...34f1 (uint8) and XXXX...34f2 (int). I hope that may be useful

I'm sorry but I cannot read it like this. Please post the services and characteristics from the logs. If I remember correctly the example does print them.

the code:

Public Sub ReadData
For Each s As String In ConnectedServices
manager.ReadData(s)
Log("SERVICE="&"00000000-0000-1000-8000-00805f9b34f0")
Log("CHARACTERISTIC1="&"00000000-0000-1000-8000-00805f9b34f1")
Log("CHARACTERISTIC2="&"00000000-0000-1000-8000-00805f9b34f2")

Next
End Sub

and the relative log:

** Service (starter) Create **
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **

Where is the DataAvailable code?

 

[tonga]

From Main:

Sub DataAvailable (Service As String, Characteristics As Map)
pbReadData.Visible = False
clv.Add(CreateServiceItem(Service), 30dip, "")
For Each id As String In Characteristics.Keys
clv.Add(CreateCharacteristicItem(id, Characteristics.Get(id)), 40dip, "")
Next
End Sub

From Starter:

Sub Manager_DataAvailable (ServiceId As String, Characteristics As Map)
CallSub3(Main, "DataAvailable", ServiceId, Characteristics)
End Sub
