Coordinator initialize had an error: Error: SRSP - UTIL - getDeviceInfo after 6000ms

Bug Report

What happened

• Zigbee2mqtt suddenly stopped connecting to my CC2531 device and thus my zigbee network went down
• The sniffer was blinking red
• After replugging to the USB port the green led returned, but Zigbee2mqtt can't connect to it anymore
• In device manager I can still see the COM port assigned

Notes

• I have tried on a separate computer which also worked with this setup, same symptoms
• I don't have CCDebugger device, so I don't know if there's a way to reset the chip itself apart from reconnecting to the USB port

What did you expect to happen

The sniffer shouldn't have started blinking red and then stopped working

How to reproduce it (minimal and precise)

I can't tell

Debug Info

zigbee2mqtt version: 1.6.0
CC253X firmware version: CC2531_DEFAULT_20190608
log output: https://pastebin.com/7h47yRJ5

I've upgraded to the dev branch to see if this was a bug and thus maybe it was fixed, but unfortunately not. The startup failed a lot quicker this time.

Here's the console output: https://pastebin.com/EwGFY7w2

This is pretty similar to danielwelch/hassio-zigbee2mqtt#226

Thanks @ciotlosm I'm gonna try reflashing via Arduino (even if it's a pain) and then report back.

It's worth noting that 1.6.0 was the only version I've ever used before the crash since my whole zigbee network was created just yesterday, so in my case it probably doesn't have to do anything with upgrade rather than a probable bug in 1.6.0

[belidzs]

So after flashing the stick again with the same exact firmware it is now working again.

I'm not sure if the stick got corrupted because itself, the host or the software however the issue you linked suggests that it has to do with Zigbee2mqtt

I had this error several times in the last days. Reflashing always helped, but the waf -> 0.

Today the devices wouldn´t reconnect after reflashing:

Error: AF data request fails, status code: 205. No network route. Please confirm that the device has (re)joined the network.

Disconnecting them from power/ using the real switch helped.

I'm also seeing this issue, same versions. I'l admit that the many references to reflashing don't sound very comforting... why would you ever need to reflash except for an upgrade?

What I have seen:

• I can get zigbee2mqtt to start
• after a while, devices still show up as active in Home Assistant, but they refuse to change state
• if I attempt to restart zigbee2mqtt, it fails to start after logging "Error while starting zigbee-shepherd, attempting to fix... (takes 60 seconds) (Error: SRSP - SYS - osalNvRead after 6000ms)"
• after unplugging/replugging the stick, the whole cycle starts again

Something even stranger: I left home for a week, and the stick was completely unresponsive. The red was on continuously, and the reset button didn't do anything. I reflashed the stick, and it went back to the cycle described above.

Do we have any leads? Any debugging info I might be able to collect?

[Koenkk]

• How much devices are in your network?
• Do you have the availability or report feature enabled?

[belidzs]

When the incident happened I had 3 bulbs, a motion sensor and 3 steering devices in my zigbee network. All of them made by IKEA

I had the report feature specifically enabled. I don't know about the availability feature but it wasn't explicitly enabled in the config

[Koenkk]

I also recommend trying with the latest dev branch as it uses zigbee-herdsman instead of zigbee-shepherd (#1888)

[belidzs]

@Koenkk after I reflashed the stick I've also upgraded to dev and since then the issue hasn't happened again.

[Koenkk]

Great, then I will close this for now, feel free to re-open once you run into problems again.
