Device Config: physical_devices doubt: phy0 vs radio0

[nemesifier]

Is there difference between phy0 and radio0?

In the nodewatcher-agent example posted in #1 both are mentioned but only radio0 has a definition.

Via openwrt ubus I see no mention of any phy object, but I see mention of radio0 (via ubus call network.wireless status, just it doesnt have the information contained in our physical_devices section, but something slightly different.

Via the iw command I see that interfaces reference a phy object, and iw phy returns all the capabilities of the physical device.

I am a bit confused. Can anyone bring some clarity?

radio0 comes from the UCI configuration section name while phy0 comes from the driver in the kernel. The physical device associated with a wireless interface in UCI may be configured using the phy attribute, for example:

config wifi-device 'radio0'
    ...
    option phy 'phy0'

This is how you configure multiple radios on a device. You may also use the MAC address using the macaddr attribute.

I am not sure how this is for non-mac80211 drivers.

thx @kostko - in the meanwhile i'm trying to get more feedback on other channels, will post here updates

information from Jow (openwrt):

phy0 is a mac80211 specific concept
radio0 is an abstract openwrt identifier for "first radio"
on mac80211 this usually maps to pyh0
on proprietary broadcom it would be wl0
on atheros it would be ath0
and so on

I think it's clear now
