Hello all,

I cannot reconnect COM port of a BLUENRG dongle after reseting.

I call NVIC_SystemReset(), dongle resets, but cannot reopen same COM port to comunicate with device.

I'm using latest Virtual COM Port driver (1.4.0).

Regards,

Are you closing the (virtual) COM port on your PC before the USB stack restarts on the MCU?
