Hi,
I'm making an firmware for the nrf52840 that communicate throw usb to a computer.
First I used the uart library that works fine but required the Jtag and Jling which is integrated to the development board to be seen by the computer as a serial communication port.
But my objective if to put the firmware on nrf52840 dongle that don't have the Jtag and Jling.
After few research, I found that I need to implement the USBD_CDC_ACM to my firmware which permit to be able to see the serial port on the computer.
However, for my use case, I need to not close the serial connection during a board reboot (with JTag, when the board reboot, the serial port doesn't close and so, my program on my computer doesn't need to reopen the port and can just wait a serial event) but with usbd_cdc_acm the serial port is automatically closed and need to be reopen by the computer.
Is it possible to change that ?
Also, is it possible to disable the DTR (Data Terminal Ready) capability of Usbd like its done with JTag and Uart ?
Regards
