I use my edison with hostapd. I manage to connect many smartphone on it.
I have a audio streaming app and all smartphones receive in real time the audio streaming.
But I have an issue. For the first connexion, smartphones take lonnnnnnng time to be connected, something like 60seconds.
start 10.0.0.79 # default: 192.168.0.20
end 10.0.0.245 # default: 192.168.0.254
interface wlan0 # default: eth0
emaining yes # default: yes
pidfile /var/run/udhcpd-wlan0.pid # default: /var/run/udhcpd.pid
opt subnet 255.255.255.0
Thank you for contacting us
I just connected a smartphone to my Edison, and it took me longer than you (2min), I think that's how it usually works.
Personally, I have not found anything to reduce this time, so unfortunately, I do not have a recommendation for you in this case.
