Bluetooth Firmware Upgrade

I created a key part of the firmware for all MTronic devices: their ability to upgrade the firmware remotely. The update architecture contained source verification, firmware integrity checks and rollback in case of faulty updates. This allowed us to push feature and security updates to devices that were already in use by the customers. Naturally, the update mechanism was developed, tested and verified in a much more thorough way, relative to other parts of the firmware, as it is arguably one of the most critical features of any IoT device.
