I've merged the PR to disable the watchdog for now as we can always re-enable it later. I think https://github.com/zigpy/zigpy-xbee/pull/173 may be the proper fix for this problem but I...

I've reimplemented this PR on top of the unreleased [zigpy priority lock/queue](https://github.com/zigpy/zigpy/pull/1297): ```bash pip install git+https://github.com/puddly/zigpy@zigpy/priority-lock ``` This should deprioritize transmit commands so that any watchdog polling task would have...

If the key is unknown, I think it should be treated as unknown. Implicit key rotation or anything that can permanently affect a production network isn't something I think we...

@Shulyaka Could you change the encryption key to all null bytes and post another backup? I don't have an XBee 3 to test with, unfortunately, and it doesn't look like...

I think the first four bytes of each `|` pair are the size of the contents of each. ``` [uint32 size][2 byte fw ver][uint32 size][16 byte nonce][trailing data] ``` I...

Could you also include the network key? Just so that we have some concrete bytestring to search for to test if decryption was successful.

I played around with alternate block cipher modes, nonstandard constructions, and various CTR schemes. Unfortunately, I haven't had any luck decrypting it. I think there may be a key derivation...

I played around with it but didn't have any luck with Ghidra, unfortunately 😓. The XBee3 actually runs EmberZNet and seems to be based on (or is) the EFR32 Cortex...

@Hixie I can mail you all the required hardware if you're in the US but I can't guarantee the software will work flawlessly. If nobody else is interested and I...
