WiFi Soft AP sample

from nanoframework

Major changes are:

1. changed to use with ESP32
2. changed to nanoFramework.System.Device.WiFi.1.4.0-preview.6 package naming style
3. add very dirty implementation of DHCP server when in AP mode to make it easy to connect from mobile
   • there is some limitations in DHCP it is not store any client address information, whenever make new connection it will assign next IP address
   • first dynamic IP address start with next to AP IP address
   • it is not sending gateway IP to Client to not block mobile device network connection while connected to AP
   • there is some changes in WebServer implementation WiFi config moved to http://192.168.4.1/config

-- rest part of readme is not changed

Shows how to use various APIs related with WiFi Soft AP. Starts a Soft AP (Hot spot) and runs a simple web server to configure the Wireless connection parameters.

The sample uses GPIO pin 5 to switch back into the SoftAP configuration mode. When pulled to ground on boot will switch into Soft AP mode.
You can connect to the web server via the url http://192.168.4.1/

Once you save the wireless configuration the next boot the device will automatically connect to that Access Point and the Soft AP will be disabled.

Hardware requirements

An hardware device with WiFi networking capabilities running a nanoFramework image.
