TIP
The firmware in field devices is updated wirelessly.
When an update operation is started on the gateway side, the field device initiates a Join operation.
Since the update operation must wait for up to about 30 minutes for the Join operation to complete, it is recom-
mended to start by updating the communication stack of a field device.
To update the sensor board firmware you first have to update the communication stack. Updating takes about 11
hours to complete.
