Question about TCP IP Stacks

Postby ruppie » Sat Jan 20, 2018 1:43 pm

Hello,
is it possible to sue other TCP ip Stacks than lwIP on ESP32, like CycloneTCP ?

Thanks in advance

Hi Marc,

This is technically possible, and the tcpip_adapter component and LWIP ethernet driver in ESP-IDF contain all the LWIP-specific glue between the WiFI driver and LWIP. However, we don't have any examples or guides for porting other TCP/IP stacks to ESP-IDF. At least, not yet.

Angus

EDIT: I missed that CycloneTCP lists ESP32 support on their website. Looks like they have already done the work to integrate with ESP-IDF, but you'll need to follow this up with them.

Hi, may I ask, what is the benefit of CycloneTCP over Lwip?

@Angus:

I see, i forgot that the cyclone stack uses an PHY and MAC Driver ;-)
As long as there is no support of ESP-MAC it won't work ;-)


Question is answered .
