Components

  • BLE GATT server application, running RIOT-OS
  • Python firmware update client, running on GNU/Linux

Usage

  • Compile wolfBoot and the GATT server application using:
make
  • Connect the nRF52840 Development Kit and use the following command to upload the bootloader and the version 1 of the signed application to the board:
make flash
  • Prepare an update package using:

  • You can check the current version running on the target, either from a USB-serial console on /dev/ttyACM0 by typing info into the shell, or by reading the BLE GATT characteristics of the device.
