Hi Sylvain. How I told you, I am facing problems with TCP-PPP in lwip scenario. Then I decided use just a raw lwip code to reproduce the problem and, if it is possible, could you use it to reproduce in your environment. I fetched my git repositoy today (15/jan). Hashs: - lwip: e03

Hi Sylvain! Thanks for the prompt reply, much appreciated. The version in use is HEAD - july/2015. You asked about incoming bytestream level check. But I understand that the exception is happening at output level, in packets generated by the lwip core. Am I right? Remembering that the UDP protoco

How are you doing? I am facing a problem in the use PPP-lwip. I have a application (app) using lwip stack. The app implements an echo message server (messages replier). The connection is through the PPP protocol (serial interface) no ethernet conection. When UDP messages are exchanged all is worki

Looking at your frames, the SIM900 outputs a PPP frame with HDLC address and control bytes, while the SIM5216 does not. I'm by no means a PPP expert, but just looking for PPP in wikipedia shows this: /The Address and Control fields always have the value hex FF (for "all stations") and hex 03 (for
