Touchlink scan fails with errors

[andrzejpolis]

What happened?

When I scan for Touchlink devices I get errors and no devices are detected. Frontend logs contains a sequence of

Info 2024-06-03 11:24:42`Set InterPAN channel to '20'`
Warning 2024-06-03 11:24:43`Scan request failed or was not answered: 'Error: {"target":null,"apsFrame":{"profileId":49246,"clusterId":4096,"sourceEndpoint":0,"destinationEndpoint":0,"options":0,"groupId":65535,"sequence":0},"zclSequence":0,"commandIdentifier":1} timed out after 500ms'`

with different channels. Same result for each.

I'm using new ember driver and Sonoff Plus V2 with firmware 7.4.3. Did not have a chance to check if it worked before with ezsp as did not have Touchlink remote back then.

What did you expect to happen?

Device scan finished and Touchlink device successfully discovered.

How to reproduce it (minimal and precise)

Just click Scan in Touchlink tab

The same issue applies to my environment. I had a couple of devices integrated, used ZHA before. Some time is stopped working and I decided to switch to Zigbee2MQTT and ember ncp-uart-hw-v7.4.3.0-zbdonglee-115200.gbl

Zigbee is starting well, but no devices are found.

Im in the same boat, updated to the latest firmware and all my units are gone. I dont have a hue bridge. All others can be re paired, but hue are a pain to get in pairing mode. If anyone have a easy way with out buying a hub please message me or should I count them as bricked?

This error means the device (e.g. the bulb) didn't respond to the scan request, not something that can be solved from z2m. It may help to reconnect the bulb to power.

Noting helps to get them back into ten network. also after a few hour with out power of them in a box won't get them to connect or enter pairing mode. Also I have alot of network route errors. Some how the old lamps are still there as ghosts and they try to route traffic thru them.

So as it loos so are the hue lamps a no go and I have to rebuild the whole setup. no real biggie, but a disclaimer or something that warns people that you might lose the whole setup or there might be alot of error and you need to redo the whole setup. That this isent just a 5 minutes flash. And for safety remove all hue bulbs from the network if you don't have a hue bridge laying around.
