"zigpy radio ... info" works but "zigpy radio ... backup" doesn't #1403

Closed IgnacioHR closed 1 month ago

IgnacioHR commented 1 month ago

Hello,

I'm trying to migrate from ezsp to ember as indicated here: https://smarthomescene.com/guides/how-to-use-ember-driver-with-efr32mg21-zigbee-adapters/

First step is to take a backup of current radio so I installed this repository in my computer running zigbee2mqtt. I'm having issues trying to obtain a backup. Here is what I'm doing and the configuration I've.

  1. I stop zigbee2mqtt using systemctl stop zigbee2mqtt
  2. I test access to the radio using zigpy radio --baudrate 115200 ezsp /dev/serial/by-id/usb-ITEAD_SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2_20240101000000-if00 info and it works. I receive the PAN ID, channel, Channel mask, etc...
  3. I try to backp using zigpy radio --baudrate 115200 ezsp /dev/serial/by-id/usb-ITEAD_SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2_20240101000000-if00 backup and this is what I obtain:

so, how can `info` command work and `backup` command fail?

This will be fixed by https://github.com/zigpy/bellows/pull/625

info performs a "quick" backup just to get basic information. backup loads everything possible and there is currently a parsing issue with one command. Feel free to try the PR, it should fix the problem.

Thank you! I'll move from this point on
