Hi,
i scan my Geonaute BLE HRM, and have thys LOG:

** Service (starter) Create **
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
BLE Supported: true
** Activity (main) Resume **
Scan

** Activity (main) Pause, UserClosed = false **
But i don't ablie to convert the CharVal

It's possible have same help?
Thanks

I'm not sure that I understand. What are you trying to do? What is CharVal (post the code that print these logs)?

I use BLE library

B4X:

Sub ble_Connected(Services As Map)
   Log("Connected:")
   
   Dim mCh     As Map
   mCh.Initialize   
   For i = 0 To Services.Size -1
     Serv = Services.GetValueAt(i)
     Log("  Srvice[" & i & "] = " & Services.GetKeyAt(i))
     mCh = Serv.GetCharacteristics
     For x = 0 To mCh.Size -1
       Log("  CharKey(" & x & ") = " & mCh.GetKeyAt(x))       
       Log("  CharVal(" & x & ") = " & mCh.GetValueAt(x))
       
     Next
   Next

End Sub

You need to call ReadData or ReadData2 and then handle the DataAvailable event.
