Raspberry Pi 5 -110 error

Configuration
1

On my new Pi 5 (8GB RAM, HA running on NVME drive) I’m seeing:

OS Version : Home Assistant OS 14.2
Home Assistant Core: 2025.2.4

ha > [189068.899514] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110
[189068.899430] brcmfmac: brcmf_cfg80211_dump_survey: Get Phy Noise failed, use dummy value
ha > _

I can’t seem to find any information on this error. Everything seems to be working as it should.

Hello The_Elf,

Are you connecting via WIFI?
That looks to me like some kind of networking thing and it is using a fallback.

Thanks for the response. No, I’m connected via Ethernet cable.

It seems that every problem I hit with HA, nobody has ever seen it before.

If you google ‘brcmfmac: brcmf_cfg80211_dump_survey: Get Phy Noise failed’ you get some commits in the Linux kernel, but I don’t know what they mean.

It’s an error that is related to WiFi. If you don’t use it, just ignore it.

Thanks. Is there a way to disable Wifi to rid myself of this error message?

Look here: https://www.reddit.com/r/homeassistant/comments/1g0c6fg/turn_off_bt_wifi_on_raspberry_pi_5/

But if you ever want to fall back to using WiFi, such a change might be something to easily forget. You could also just ignore the error that gets thrown.

Thank you. It’s a shame the error message isn’t more meaningful.
