Hello. I have a reasonably short term need for FreeRTOS+TCP over PPP so that I may use TCP+TLS over a modem. The most recent update I’ve been able to find is here, where in Apr 2016 it wasn’t on the immediate roadmap: https://sourceforge.net/p/freertos/discussion/382005/thread/163f3ed7/ After the Amazon announcement, I explored the repo and found that the supported interfaces still don’t include PPP: https://github.com/aws/amazon-freertos/tree/master/lib/FreeRTOS-Plus-TCP/source/portable/NetworkInterface I understand that the project has many priorities, and that WiFi or hard-wired Ethernet may be the dominant focus. That said, since I can’t seem to find any recent discussion on this topic, would you mind giving an update to set expectations within the community? A swag is really all that is needed (i.e. actively being worked on and “close”, vs actively being worked on targeting , vs not yet prioritized/scheduled, etc). Even if it’s not in the cards for my “reasonably short term” needs, it would be helpful for us as software devs to understand roadmap prioritization (i.e. relative to other big ticket items) so that people can determine whether or not it’s best to pursue other paths based on their own specific needs. Thanks very much.

I’m afraid there is still no PPP implementation in development. Not sure if somebody else has one.

You might try to google “ppp implementation c” and find several implementations. If you decide to develop your own implementation, this forum can answer the questions that you’ll have about the internals of FreeRTOS+TCP.

Thank you.

… working on PPP + lwip + sockets on ATSAMD51 with FreeRTOS as configured by Atmel Start. I am not sure how proprietary the project owner will be about it after paying to get the pieces spliced together, but when it is working, I’ll ask… I will say pulling lwip into a FreeRTOS based project was easy. the ppp built in clearly defines the sio.c interface needed for serial IO… Also had to throw MBEDssl on top of it for HTTPS – compiles but untested.
