B4R Question Problem with multiple UARTS

[Nefarious19]

Hello Guys,

I tried to compile code below to use other hardware uarts on my Arduino boards but i get an error. Can you explain wthat i'm doing wrong? Thank you in advance for help.

#Region Project Attributes
    #AutoFlushLogs: True
    #CheckArrayBounds: True
    #StackBufferSize: 300
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
   
    Public SerialNative1 As Stream
   
   
End Sub

Private Sub AppStart

    RunNative("SerialNative1", Null)
End Sub

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

The Arduino Nano has only one serial port.

You can use the default Serial1 object (remove the inline C code) or you can use SerialSoftware to create software based serial ports.

I know that Atmega328p has only one uart but i thoutgh that i can use each uart in this way. What if I don't want to use uart as Log but as a serial communication with other modules? In Arduino Mega compilation process ends with no error in this moment when i'm choosing Serial2.

You can use Serial1 for whatever you like. Just don't call Log as it will write to Serial1.
