Delta / Mbed 2 deprecated BLE_WIFIControl

Using BLE to control WIFI configuration as SSID and PW.

Dependencies:   BLE_API WIFI_API_32kRAM mbed nRF51822

Fork of NNN40_WiFi by Delta

BLE_WIFIControl enables user to setup Wifi connection via BLE link. Here is iPhone app that teaches you how to use this BLE_WIFIControl example. /media/uploads/Marcomissyou/ios_app_for_wifi_configure.pdf
