By searching pppos support, I find your issue in esp-idf project, and I meet some similar problem in my code.

With the code in official pppos example

I got the output like this.

terryding77 commented 2 years ago

I never get the ip from ppp dialog, and I find write PDP_CONTEXT s command not work for my sim7020; MODEM_CHECK(dce->define_pdp_context(dce, 1, "IP", CONFIG_EXAMPLE_COMPONENT_MODEM_APN) == ESP_OK, "set MODEM APN failed", err); but it works if I read the CONTEXT:

command
AT+CGDCONT?

got answer
+CGDCONT: 1,"IP","CMNBIOT","100.121.10.100",0,0,0,,,,0,,0,,0

so I comment the PDP_CONTEXT function in above code.
