I want to make a project in which I have two (or more) Arduino, each one has an ESP8266 Wifi Shield connected with it. I want one Arduino to send a file to the other one through the shield. Is it possible? Some reference material, or tutorial, or some useful information would be very appreciated.
Or another possibility is to use an NRF8001 with the Arduino (instead of the ESP8266). Will that be possible? Some reference for that as well will be very appreciated.
Can you help me compare which technology (BLE or Wifi) would be more suitable to transfer files to and from Arduino (any files, usually text files, but they can be of some other format as well).
The files which the this "transmitting and recieving modules" recieve will come to another arduino wired with it. Same for transmitting purpose, the file to transmit will come from another arduino wired with it.
