5.1.2 Programming the LoRaMote through the USB-Bootloader
By default, the firmware will boot and run directly the LoRaMac application. There is a small manipulation
to perform to enter in USB-Bootloader mode and the process is the following:
-
Power down the LoRaMote
-
Remove the LoRaMote battery
-
Connect the USB cable to the mote
-
Then, to enter in bootloader mode, it is necessary to have a finger pressed against the SAR
sensor present on the back of the RF antenna. Please, refer to the picture below.
-
The user can then power-up the mote through the side switch while keeping its finger
pressed on the SAR sensor as shown below:
The user should then see the three LEDs flashing at a one second interval which indicate the platform is
now in bootloader mode. If the three LEDs are not flashing, then the process must be done again as there
was an issue with the detection of the finger on the sensor antenna.
