Delta / Mbed 2 deprecated NNN40_RPC_HTTP-Server

NNN40 run a HTTP server with RPC using Soft AP mode

Dependencies:   WIFI_API_32kRAM mbed

Fork of HTTP-Server by Francois Berder

The sample code will run as a WiFi Soft AP mode with given AP configuration setting including SSID name and password. IP address (fixed to 192.168.2.1 for the current version of WIFI_API)of AP router will be print out once Soft AP mode is operating.

User can open their web browser and go to http://192.168.2.1/. and have a try on switch on a led. Firstly, we need to create an object to control a led

/media/uploads/wgd8700/http_server2.png

Then, led can be switch on using RPC command /media/uploads/wgd8700/http_server3.png
