USB direct mode

Note In order to use USB direct mode in Digi XBee development kits, you must use the XBIB-C-TH development board.

Note You should use this mode if you want to connect using PPP through the cellular modem while using a host operating system, such as embedded Linux.

This mode allows you to access the XBee 3 Cellular LTE-M/NB-IoT's USB interface directly through XBee pins 7 and 8. VBUS functionality is optionally provided on XBee pin 6 if you wish to enable and disable USB mode based on an external source. While in USB mode the cellular modem is not able to communicate serially with the XBee MCU. All communication with the cellular modem must be performed by the user via the USB port.
