LWIP usage in firmware
Posted: Wed Feb 18, 2015 5:33 pmLS,
I am experimenting with adding functionality to LUA firmware and trying to understand the network implementation.
I noticed that all net functions currently are using the espconn interface, but there is also the (a) lwip interface present in the project (even in source format). I tried to add rudimentary udp and tcp servers to the net.c using the LWIP raw interface and that was working.
- Is there a specific reason for the espconn usage in current nodemcu ?
- Are there knows issues using the direct LWIP interface ?
EDIT: Also found today the espconn.c in the LWIP app directory.
- Isn't espconn part of the SDK ?
- Are you maintaining a local copy of espconn in nodemcu?
Kind regards,
Herman
