You can notice that PPP negotiated up to a running session in your log, which is quite a good news. The pppos_input() function in lwIP 1.4.x is not thread safe, maybe that's the issue. You could try setting PPP_INPROC_MULTITHREADED but the name is misleading, that's only IRQ safe (i.e. [lwip-users] ppp over serial using gsm modem getting config acknowledgement reject packet., rohanm, 2015/02/18 Re: [lwip-users] ppp over serial using gsm modem getting config acknowledgement reject packet., Sylvain Rochet. * PPP over serial using HDLC-like framing, such as wired dialup modems or mobile telecommunications GPRS/EDGE/UMTS/HSPA+/LTE modems * PPP over Ethernet, such as xDSL modems. Power your GSM module with good power supply, using LiPo battery is recommended. In this example hardware flow controll is not used. With 2G (GPRS) module it is not needed. Safe with one way preemption and different priority) but not thread safe. Or better, you could try lwIP 2.0.0 Beta1, where the PPP stack was fully reworked if not totally rewritten.
