Farady.Had you understand what are the proposes of switches? Can you share some information about it?
Do you have information about Pins? With one is in use by this shield and with I will be able to use on a next shield layer?
Or better to use software serial for the wifi shield.
>If yes then do I just set the esp8266 to AP mode or do I have to set any other configuration in order to accept data over wifi?
when I connect my android to the SSID of the arduino uno wifi >how do I send data? Plain data as string "hello" or AT commands?*That I know of AT commands usually are send over serial hardwired Tx/Rx pins and not over wifi
where do I find the story behind APIs?
I try and search the Github files for any mentioning of the AT commands and in the only file I see this , is in the EspDrv.cpp, So is this the "translator" of the AT commands to Arduino language?
*I think there must be another configuration in order to send AT commands through wifi!
