Configuration and Setup
A number of flexible and easy-to-use options are available to set up a module running BGX BLE.
Perhaps the most common option used for general setup (and also the most convenient when prototyping) is to use a terminal application and serial interface such as a UART. See Getting Started.
You can save the current variables to flash, so that they persist after reboot, with the save command.
To return all values to their factory configuration, use the
The fac command requires the <BD_ADDR> argument in order to avoid accidental reset.
GPIOs are configured with the commands gfu, gdi, gse, and gge. GPIO configuration and initialization is also saved by the save command.
GPIO configuration and usage is available using the get gp u command sequence.
Serial Firmware Update
The Bluetooth Xpress device can be updated via the serial port. This feature is sometimes called DFU (Device Firmware Update). In the future, Silicon Labs will provide a DFU Utility to allow firmware udpates using the serial port. To be notified when the DFU utility is available, please request the tool through email to firstname.lastname@example.org. Until then, the Bluetooth Xpress device can be updated using the BGX Commander mobile app.
