Upgrading Beacon Firmware

•
After a couple of seconds the magnet can be removed, and the Beacon status LED should flash red at a
slower rate to show Bootloader Mode has been activated.
Once activated, Bootloader mode only provides support for reprogramming the application firmware.
To leave Bootloader mode, remove the magnet and cycle the power to the beacon. The Status LED should flash
Green to show the main application has started.
In Bootloader mode, the serial port data rate is fixed at 115200 baud and cannot be altered by the user.
If you have been experiencing problems connecting the programmer software to the beacon. Try reconnecting
using the above setting once Bootloader mode is active and see if this resolves the issue.
Bootloader mode only activates a small
subset of the Beacon’s hardware –
enough to provide serial
communications, and status indication. Consequently, only the Status and Programming serial command set is
implemented, so developers and system integrators using higher-level functions will find these no longer work
while the beacon is in Bootloader mode.
If you are having trouble activating Bootloader mode using the method described above, an alternative method
is available that involves making hardware changes
