BlueTooth AP Name

[mitsusdev]

Hi,
i want start bluetooth serial listen, changing default B4A access point name.

Is it possible using only Basic4Android or i must change serial/bluetoothAdmin library?
i've tried this solution, initially for show into my code the name and then change it, but i get some errors:

devices_view_click (B4A line: 625)
Name = rT.RunMethod("getName")

java.lang.NullPointerException

This is my code:

Dim i As Intent
i.Initialize("android.bluetooth.adapter.action.REQUEST_DISCOVERABLE", "")
                  
i.PutExtra("android.bluetooth.adapter.extra.DISCOVERABLE_DURATION", 300)
StartActivity(i)

Dim rT As Reflector
Dim btIntent As Intent
btIntent.Initialize("","")
rT.Target = btIntent.GetExtra("android.bluetooth.device.extra.DEVICE")
Dim Name As String
Name = rT.RunMethod("getName")
                  
Log("BlueToothName is = " & Name)

Log("Start bluetooth listen...")
serial1.Listen

You shouldn't create the intent yourself.

You should add an intent filter as described in this thread: http://www.b4x.com/forum/basic4andr...ct-if-your-connected-bluetooth.html#post94499

mitsusdev:

Can you show how you was able to get the BLUETOOTH name ?

Using this :
"http://www.b4x.com/forum/basic4android-updates-questions/16555-detect-if-your-connected-bluetooth.html#post94499"

I can get the ID number only, but not the NAME.

Thank you:

You can use Serial.Listen2 and set the name.
The UUID should be: "00001101-0000-1000-8000-00805F9B34FB"

Hi Erel

I tested, but not change the name.

Thanks
