miketedeschi:
the hardware aspect is in my wheelhouse...cant believe this doesn't exist.if someone else wants to step up and help with the library, i can easily make the board.
here is an example of an arduino variant i made that has a built in esp8266 module and a built in OLED display.
i can do the hardware if someone else does the software....
That is nice ....
Software library would be almost identical to GSM shield because it also uses AT commands, it shouldn't take much effort to replicate GSM shields library into dialup one
By the way why do we even need a library? Serial port Dialup modules can communicate with Arduino core all we need to do is send few AT commands and read reply
(this is just my guess I'm no expert)
