PPP Events (IDFGH-7883) about esp-protocols HOT 5 CLOSED

Hi @AshUK

Which version of IDF are you using? This should work correctly on latest v5.0-dev and v4.4, but I recall we had some issues with event propagation on some older branches.

from esp-protocols.

We are targeting v4.4.1.

Strange, this must work. Could you please share the initial part of setting up the esp-netif and modem's DTE?

Note, that there's also a run-time configuration in esp_netif_ppp_config_t that could enable/disable the phase/state events separately (but the error event should be enabled by default). Could you please try to call esp_netif_ppp_config_t() API after creating the interface:

    esp_netif_config_t ppp_netif_config = ESP_NETIF_DEFAULT_PPP();
    esp_netif_t *ppp_netif = esp_netif_new(&ppp_netif_config);
    assert(ppp_netif);
    esp_netif_ppp_config_t ppp_config = { true, true };
    esp_netif_ppp_config_t(ppp_netif, &ppp_config);

from esp-protocols.

Ahh this makes sense, thank you very much, now using esp_netif_ppp_set_params I am now seeing all the events come through as expected. The misnomer was were seeing NETIF_PPP_ERRORUSER errors on init as we always exit PPP mode regardless of config.

from esp-protocols.

The flow of events for anyone reading this is the future.
