B4R Question Mega, serial port 1 no response

[Mostez]

I tried this example to activate serial port 1 and 2 on Arduino Mega, serial port 2 (Serial HMI LCD) is working OK, but i get no response from port 1(Serial RFID Module), any ideas?

Thanks

Sub Process_Globals
    Public LogSerial As Serial
    Public DWINstream As AsyncStreams
    Public RFIDstream As AsyncStreams

    Public SerialNative1 As Stream
    Public SerialNative2 As Stream

    Public BC As ByteConverter
End Sub

Private Sub AppStart
     DWIN_VALID_PACKET = False
     RunNative("SerialNative1", Null)
     RunNative("SerialNative2", Null)
     ScreenTimeoutTimer.Initialize("ScreenTimeoutTimer_Tick",1000)
     ScreenTimeoutTimer.Enabled =True
    
     RFIDstream.Initialize(SerialNative1,"ReadRFID","RFIDerr")
     DWINstream.Initialize(SerialNative2 ,"ReadDWIN","DWINerr")
    
     LogSerial.Initialize (115200)
    
      ToggleBacklight(True )
     Delay (3000)
     GotoPage(DWIN_SCREEN_START)
     Buzzer(0x0A) 'buzz 100 MS
     MainDwin
End Sub

#IF C
void SerialNative1(B4R::Object* unused) {
::Serial1.begin(9600); //<--You can change the baud rate
b4r_main::_serialnative1->wrappedStream = &::Serial1;
}
void SerialNative2(B4R::Object* unused) {
::Serial2.begin(115200); //<--You can change the baud rate
b4r_main::_serialnative2->wrappedStream = &::Serial2;
  }
#END IF

The code you posted is correct. The problem is somewhere else.

thanks Erel, i will replace RFID module and see what will happen

something wrong with my Arduino, bought new one, it works now

everything was working OK, until I installed Ethernet-SD Card shield, HMI device works fine(Serial2), but i get no response from Serial1, I have to remove the Ethernet shield to get stream, tried to change to serial3 instead, same thing also, had to remove the shield, any ideas!

Thanks
