Firmware Update
The factory firmware that is provided with the module may be quite out
of date. You should perform a firmware update to ensure that you have
the latest firmware. You can do this either over Wifi client connections,
or via an SD CARD.
We recommend using the auto update system. This will be preconfigured if you have used the
setup wizard. The automatic updates are done within a selectable hour of day, and only if Wifi
connectivity is available at the time.
Flash from Web
You can typically just press the ‘Flash now’ button and wait for completion.
Flash from File
Using an SD CARD formatted as FAT, download the firmware update and place it in a file called
‘ovms3.bin’ in the root directory of the SD CARD. Once the SD CARD is inserted the firmware
update will start immediately.
