Since the ESP8266 supplies, as far as I understand it, everything up to tcp and udp, I would propose not to write a netdev driver for it, but writing a netapi threads directly, one for TCP and one for UDP, so our future new socket API speaks directly to it. If you need some inspiration how to implement a transport layer thread have a look at Hauke's prelimanary UDP implementation [1]. > The trick with the ESP8266 modules seems to be to use the LUA firmware. > And use some simple serial bridging code from Riot to then talk to the > modules. > If there are no timing issues over speaking to the devices registers over e.g. SPI directly (if it is possible this way at all), we can try that, but in general I would prefer the solution that yields the better performance. > Let me know if this is an interesting option? > Since it would show the flexibility of our new network stack this chip would be a great option! :-) Regards, Martine [1] https://github.com/RIOT-OS/RIOT/pull/2430
