Send telemetry on Serial1 when Arduino nano Every + Arduino Nano LED Matrix display

hello to the whole team

I'd like to add a display with a matrix of LEDs to give the start (countdown followed by GO!) and then display the position of each car and the number of laps covered. This information is available in the telemetry sent to the USB port. You cannot link 2 arduino directly via the USB port. When you add an arduino nano to manage the matrix, you need to send the data to the TxD Serial1 port on the arduino Every. I modified the program as follows: SerialCommand serialCommand = SerialCommand(cmd, REC_COMMAND_BUFLEN, EOL, &Serial1); // get complete command from serial and the telemetry arrives on serial port 1 of the Arduino Every. But we lose the USB link for configuring the game via the desktop application on the PC. My question : Could you add a function that would send the telemetry to the Serial1 port, in addition to sending it to the USB Serial port? We need : R4 p1M1,25,100 p2M1,55,100 ... w1 R8

I'm just a maker, not a developer. I can write a basic program on Arduino for simple projects, but here there are many libraries, .h and .cpp files and I'm a bit afraid of making a mess ... Thanks in advance Francois www.framboise314.fr
