2.6 Firmware updates
The base unit firmware can be updated only locally using Produal MyTool
®
.
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.
2.7 Measurement data sending interval
The measurement data can be read from the transmitters based on the base unit polling, with fixed
interval and with a Change of Value (COV) function.
Transmitters send the measurement information to the base unit according to the base unit polling
interval. The base unit requests the measurement information according to this interval even if other
data sending methods are also selected. The interval can be set to 60...65535 s (1 min...18 h).
In COV mode, the transmitter sends the measurement data also when the data changes. If the value
has changed more than the given hysteresis, this data is sent to the base station. The measurement is
continuous in transmitters with wired power supply. In battery powered transmitters, the measurement
is activated according to the network activity interval. The network activity interval can be set to
10...65535 s.
Note:
Short interval may significantly shorten the battery life.
Note:
The COV mode may significantly shorten the battery life if the hysteresis is set to
very low value.
If the fixed interval is selected in the transmitter, the measurement data is sent to the base unit also
with this interval. The interval can be set to 30...65535 s.
Note:
Short interval may significantly shorten the battery life.
