I have a FRDM-K64F based project running using RTCS IP stack. Now I want to add Wi-Fi communication to it, keeping the IP stack implementation and usage most transparent possible; so I need a Wi-Fi adapter, right?
My first attempt was ESP8266 with a customized firmware , but I think that's not possible to create the following topology :
K64F board <---PPPoS---> ESP (station) <---> Access-Point <---> Internet
The ESP's big brother ESP32 seems to have RMII pins. I thought connect it to the K64F's MK64FN1M0VLL12 pins, but both have RMII clock in master mode . However, ESP32 will be lauched late at June/2016.
My next attempt is those cheap WiFi dongles (like most of the IoT approaches for Raspberry Pi).
I suppose to accomplish Internet connection with MQX I need a driver, right? What is the steps to crete a driver to those USB Wi-Fi devices?
