I have an Arduino in a remote location and would like to upload new code via GPRS (a SIM900 is connected to the Arduino via TX/RX serial interface with hardware handshaking (DTR, CTS, RTS connected)). I was thinking about putting the .hex file (or some format) on a webserver and Arduino will automatically check once a day if there is a new sketch available. If a newer sketch is available, the Arduino will download and update itself. I am clueless of how to accomplish this.
Can anyone point me in the right direction? Maybe even someone have accomplished this already and can share their knowledge?
