What is command 0x17?

(This device is currently flipping between dead and alive. I will manually reset it now.)

Also 0xf8, before it became borked:

Clearly some junk packets coming from device.

[Mirar]

I see.

Junk from the device or more failed checksum checks, I wonder?

[pofs]

They're not just checksum false-positives, they also have invalid length and a random content.

What's interesting, they both have the same length. Looks like device tries to send some meaningful packet (Meter report, I guess, judging by packet length), but the buffer gets randomly overwritten at some point.

[Mirar]

At first I thought all bad packets were buffer overwrites (because I couldn't in my wildest fantasy imagine an XOR checksum on a radio packet). I get so many...

I'll ask Philio about it and see what they have to say.
