I would like to transfer data from an 8-bit micro to another 8-bit micro. My question is, can I do it using wifi (ESP8266) without having a router. Can I simply transfer data from one to the other?
If I understood the question correctly, the answer is yes.Provided, both microcontrollers have a UART interface.
ESP8266 can both be an AP and an STA. So router is not needed.And there is a P2P mode too i've heard.
This is really basic firmware for the ESP that creates a totally
transparent TCP socket to ESP UART0 bridge. Characters come in on one
interface and go out the other. The totally transparent bridge mode is
something that has been missing and is available on higher priced
boards.
