Error: Failed to run hostapd, maybe a program is interfering.
If an error like 'n80211: Could not configure driver mode' was thrown
try running the following before starting create_ap:
    nmcli r wifi off
    rfkill unblock wlan

Doing cleanup.. done

This appears to be the cause: nl80211: Beacon set failed: -16 (Device or resource busy)

Found the problem: it appears my Wifi card only supports AP on the same channel than existing Wifi connection. So I have to first manually check channel of the existing connetion with iw ... info and then manually specify channel when calling create_ap.

Maybe a better error message could be added or even this condition detected and channel picked automatically instead of always defaulting to channel 1?

For the record, it looks like @sudoAlphaX has put together a PR implementing a fallback to the current wifi channel here: #450
