Hi, I have tried to update firmware in my network using UWB firmware update.
In my understanding, the process is:
- Ensure no anchor initiator in the network
- Put the new firmware to a device, say its device S (for source)
- Put the device S as an anchor-initiator, and turn the firmware update via UWB on
- Wait and let the device S sends its firmware to other nodes
I have tried this once to update from factory image DWM1001_PANS_R2.0.hex to a customized firmware, and it works.
However, I tried to do another update with the steps listed above. The outcome is instead I update the network, the network rolled back my device S to previous version of the firmware. Is there a way to ensure the firmware flow is going from source to target as Iām intended?
Also, sometimes updating the firmware makes a tag turned into anchor and lose its label. Any idea why? I have made sure that I did not set the device as an anchor in the firmware code.
