Pasting the details here I mentioned in #267. So far, the crashes don't seem random for me.

I get the "brcmfmac: brcmf_cfg80211_nexmon_set_channel: Set Channel failed: chspec=4109, -110" errors after about an hour when I have bluetooth enabled in the config, but bluetooth does not connect for whatever reason. pi0w, v1.3.0, temp shows as 41c. pwnagotchi process locks and goes defunct when this happens. Is this the same bug?

Bluetooth enabled and connected: No problems after 2 hours
Bluetooth disabled: No problems after 2 hours
