Serial Modem Host Applications

The host and the modem are on the same DK, so there is no wiring.

  1. Connect the nRF93M1 DK to your computer over USB and turn it on.
  2. Run nrfutil device list and note the DK's serial number and its VCOM0 port. VCOM0 is the host console (uart20). On macOS the port looks like /dev/cu.usbmodem*, on Linux like /dev/ttyACM*, and on Windows like COM*.
  3. For battery reports, connect a battery to the DK. Without one, the application still runs but skips the battery message.

Checkpoint: nrfutil device list shows the nRF93M1 DK.
