About:

This is a command line version of the ESPTouch SmartConfig App (https://github.com/EspressifApp/EsptouchForAndroid) written in C. Completely stand-alone implementation without any dependencies to external libraries, especially from the original App.

• Works on Raspberry.
• Works on Windows.
• Implemented but not tested for hidden Wifis.
• AES is not implemented, however it is uncertain how that is used at all - i cant figure out from the App's source where the AES-key is handled.

Build:

Build via make, then a local subdirectory ./bin appears with the executeable smartcfg.

Usage:

smartcfg ...
  [ --essid ESSID ]
  [ --bssid BSSID ]
  --password PASSWORD
  [ (--interface INTERFACENAME) | (--address LOCALADDRESS) ]
  [ (--timeout TIMEOUT) | --infinite ]
  [ --hidden | --visible ]

• If --interface is ommitted, then wlan0 is assumed. (works only on linux)
• If --address is ommitted, then the local address of the interface is used. (works only on linux)
• If --essid and --bssid are ommitted, then the locally connected Wifi is used (works only on linux). You will typically only provide these parameters, if you want to put your ESP into a different wifi of the one, your Raspi is currently booked in. Of course this requires providing the correct password of this wifi.
• The --password must always be given.

Example:

pi@raspiz1% ./bin/smartcfg --password "34234673423423"
./bin/smartcfg, ver: May 19 2019/15:20:49 ...
using local interface wlan0 address 192.168.0.141
