How can I access BT610 Canvas Sensor Firmware command line interface?

The Canvas Firmware runs on Zephyr RTOS which natively provides a bunch of useful subsystem for development purposes. One of those is a command line interface which allows - for devices product that supports its firmware - convenient device management features like configuration, monitoring or quick access to debugging tools.

The command line interface is usually accessible via UART. Access to the sensor debug UART on the BT610 is facilitated by a 6 pin header, J1, with pinout as follows :

To access J1 port directly from your PC, we'd suggest to use a UART to USB kind of cable.

Once you get connected to it, you'll have access to a similar menu via whatever terminal software that supports serial communication :
