It's maybe still not so clear,let me upload my source code and explain that.
I have an Xcode project.i wanna write an android version via b4a.I used the same command as below in my Xcode project and it's worked fine
B4X:
(void)getDeviceSN{
    NSLog(@"getSN");
    self.status=MPAGetSN;
    Byte cmd0[0x04] = {0x00,0x02,0xF2, 0xF2};
    [self send:cmd0 andLength: sizeof(cmd0)];
}

in my b4a project ,I used the same command but i can't get any response from bt device
B4X:
Sub btnSend_Click
    Dim TriggerPayment() As Byte = Array As Byte(0x00,0x02,0xf2, 0xf2)
    AStream.Write(TriggerPayment)
End Sub
