i'm building app should communicate iot device.
since iot device should connected wifi, i'd wish use app setup networking.
have seen there several app out there can want.

  1. turn off phone wifi
  2. turn on phone access point specific network name
  3. the printer connects phone
  4. the phone sends wifi details
  5. the printer connected same wifi
