I have been working on a SIM900 1 driver and a PPP stack for allowing GSM internet access in RIOT. The driver has to handle AT commands (for accessing modem’s data mode) through UART and manage the PPP connection.
Since most mobile devices work in the same way, I was thinking about developing something like a “generic mobile AT based device driver”.
For example, linux handles the dial-up part with a chat script (that consists in a list of AT commands), and then pppd does the rest. I would like to replicate the same thing in RIOT.
What do you think about the idea?
