Trying to update the firmware on a Zigstar PoE (Zigbee 2 LAN coordinator) and it kept failing with a timeout at various addresses:

I ended up going through the code and doubling (or tripling) all of the timeout values (from 2 to 4 or 8, ...) and it worked straight away after that:

server:/swdownloads/cc2538-bsl/cc2538-bsl-master# python3 cc2538-bsl.py -p socket://zigstargw.local:6638 -evw /Downloads/CC1352P2_CC2652P_launchpad_coordinator_20230507.hex

Perhaps the timeouts could automatically be extended when a network connection is used instead of a local serial one?

Hey, thanks for that, I had the same issue.
For anyone else stumbling upon this in the future a little tip, there's an unlabelled timeout on line 383, last argument to the _wait_for_ack call has 2 seconds which is just a tad too low for me.

@JelmerT Done, though a little disclaimer: These are the values that worked for me but may not be optimal for everyone. I no longer have the ability to run tests (the device has since been migrated to different firmware).
