esp32: PPP tunel for WiFi
HI
say ESP32 connects as client to home WiFi access point.
can ESP32 provide PPP internet access for linux over RX/TX serial?
(or over something similar like SPI channel)
Is there some example for this on micropython, please help
ports/esp32: Updated network_ppp.c to match current documentation
Summary
This MR updates the network.PPP module of the ESP32 port to match the current documentation. The status() method should behave like the common LwIP implementation and the poll() method will raise an RuntimeError indicating that this is not really supported on this port. Also did some minor resorting to match the common LwIP implementation.
This would solve https://github.com/micropython/micropython/issues/16998
Testing
Tested on ESP32_GENERIC and ESP32_GENERIC_S3 boards with SIMCOM800L and SIMCOM7080G modules. At least with ESP32_GENERIC the PPP connection is connected at least 18 hours.
