 I tried using NetworkManager for this first but it didn't work. May have been a firewall issue actually, but hostapd working now anyway. NetworkManager also has very limited configuration options.
+WiFi AP was (maybe) broken by wpa_supplicant changing the channel set in hostapd. It must be disabled.
+Reduce TX power:
+iwconfig wlan0 txpower 2
+How to reduce client power? AP can give clients a limit. Can also hardcode in ESP32, but not PicoW.
