Broadcast

Broadcast greatly increase efficiency and speed when upgrading many devices at the same time. It requires devices to be in connected mode, and only one firmware image can be broadcast at a time.

Firmware broadcast is started by writing property 0x8124 - Start Firmware Broadcast to gateway. The gateway will then start broadcasting firmware to all devices in it's BLE network. Only one firmware broadcast job can be ongoing in each gateway at the same time. The progress of the firmware broadcast can be monitored via property 0x8125 - Firmware Broadcast State. A firmware broadcast can be controlled by writing property 0x8126 - Firmware Broadcast Control to the gateway with a value for the desired action.
