I am designing a gateway and on my ATSAM4E16E, I have connected the LTE modem(SARA-R412M) using a USART port. I can communicate (and i have activated data mode) with the modem using AT commands.
Now, I would like to use PPPos (PPP over serial) library from LWIP 2.1.2 as tcpip stack with freertos. FreeRTOS has to implement as this project will be running in a threaded environment.
I have essayed to use this example:
Can you please help me how you have tested this pppos_client (used for ESP32) and adapted it to SAM MCU ?
Can you send a sample example that you have test in your sam board please ?
