6.5 Transmitters' firmware updates
The transmitter firmware updates can be done locally or by using Firmware Over The Air (FOTA)
function.
The FOTA function updates the devices over the wireless network. The FOTA firmware update process
can take up from few minutes to several hours depending on the network size. The base unit updates
two devices at a time and then moves to the next devices until the whole network is updated to the
latest firmware version. The update process starts from the closest transmitter in the network.
Note:
The FOTA function requires more power than the regular transmitter functioning.
Therefore the FOTA updates should be planned carefully in battery powered network. The
transmitter is not updated if the battery level is too low (under 10 %).
Note:
The whole network is restarted after all devices are updated.
