NRF_SERIAL_EVENT_DRV_ERR on disconnect

[rodriguise]

I am using nrf_serial in IRQ mode to communicate with an AT based device. When I reset the device using ATZ, I get NRF_SERIAL_EVENT_DRV_ERR -- likely because the pins go into an undefined state.

Is there anyway to recover from this state? After this happens nrf_serial_read always returns NRF_ERROR_TIMEOUT.

Thanks
