Hi @jameshorng ,
Please refer to below for my answer
Below is the Octave FOTA process, I just have done it on my device.
- Upgrade FW my device from 3.1.0 to 3.0.2. At “Recent changes” field, you can see your “FOTA_START” actions as below
- Once device completes installing new FW. The grey part near Firmware version information will disappear, and you can also observe the “FOTA_COMPLETE” action as below
Upgrading a device over the air can take a long time depending on the size of the firmware package that needs to be uploaded to the device and the Access Technology which your device is using, i.e: time for upgrade using GSM technology will longer than LTE technology.
Basically, if your device can connect and sync to Octave server successfully, it can upgrade to the new FW.
