Plans to release PPP support?

[Spider84]

Hello! Do you plan to release PPP support for next process f.e. by lwip pppos?

May be I can help? Now I discovered for structure of library and have many questions - how to make better.

I am listening :)

I has take IPCONN as example.

lwgsmr_t
lwgsm_ppp_start(void* const arg, lwgsm_evt_fn conn_evt_fn, const uint32_t blocking) {
    LWGSM_ASSERT("conn_evt_fn != NULL", conn_evt_fn != NULL);

    return lwgsm_call_start("*99#", arg, conn_evt_fn, blocking);
}

in lwgsm_init.c has added section in parser

#if LWGSM_CFG_PPP
        } else if (CMD_IS_CUR(LWGSM_CMD_ATD)) {
                if (!strncmp(&rcv->data[0], "CONNECT" CRLF, 7 + CRLF_LEN)) {
			is_ok = 1;
                } else if (!strncmp(&rcv->data[0], "NO CARRIER" CRLF, 10 + CRLF_LEN)) {
			is_error = 1;
		}
#endif

now need to forward data from uart (lwgsmi_process()) to pppoe parser of lwip. How to do it better? Also need some event to detect end of data connection...

[MaJerle]

so you rely on call event - then you can use call-based events?

m? what kind?

From your code

lwgsmr_t
lwgsm_ppp_start(void* const arg, lwgsm_evt_fn conn_evt_fn, const uint32_t blocking) {
    LWGSM_ASSERT("conn_evt_fn != NULL", conn_evt_fn != NULL);

    return lwgsm_call_start("*99#", arg, conn_evt_fn, blocking);
}

It seems that you are using call module of LwGSM library. The lib provides you events when call is being picked up or has been hanged-up
