Answers checklist.

[X] I have read the documentation for esp-protocols components and the issue is not addressed there.
[X] I have updated my esp-protocols branch (master or release) to the latest version and checked that the issue is present there.
[X] I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

The docs speak about C++ but there isn't a single C++ example. Yes I also looked at IDFGH-8031, this is also a mixture between C and C++.

Could someone post a small full C++ sample please ?

I think most of our examples use the esp_modem's C++ API. They still use the plain C API of other components (esp_event, mqtt, esp_netif, ota and others) in order to simplify things and demonstrate mainly the modem library.

What exactly do you mean by the small full C++ sample ? using C++ wrapper around general IDF components? Using Espressif C++ component from https://github.com/espressif/esp-idf-cxx? Using exceptions for error handling?

You can also check some of our test apps, which use RAII wrappers around events, mqtt and OTA: https://github.com/espressif/esp-protocols/tree/master/components/esp_modem/test/target_ota

Yeah, you're right, I think I messed up with my question. I must have looked in all the wrong places for a while and probably copied both from C++ and C examples into my own source.

The ppp_connect_esp_modem.c was probably one of the culprits (in esp-protocols/examples/esp_netif/multiple_netifs) .
