Grigorij 0 22 сентября, 2016 Опубликовано 22 сентября, 2016 · Жалоба Добрый день. Нужна помощь с библиотекой LWIP, неделю воюю с ней и никак не могу забороть. Суть в следующем. Есть плата с GSM-модемом SARA G300. Сам модем умеет только данные передавать, при этом встроенного TCP стека у него нет. Надо установить TCP соединение с сервером и отправить пакет с данными. В итоге получилось настроить модем и установить PPP соединение (PPP Over Serial Line). Собственно ниже лог установки соединения.

Grigorij 0 26 сентября, 2016 Опубликовано 26 сентября, 2016 (изменено) · Жалоба Получается PPP всегда падает после попытки TCP соединения? Похоже на то. После попытки установить TCP соединения я почему-то в какой-то момент попадаю в callback на установку PPP, т.е. вот сюда: ... pppDesc = pppOverSerialOpen(0, linkStatusCB, ctx); ... static void linkStatusCB(void *ctx, int errCode, void *arg) { struct ppp_addrs *addrs = arg; if (errCode == PPPERR_NONE) { DBG("PPP connection was established\n"); DBG("ip_addr = %s\n", ip_ntoa(&addrs->our_ipaddr) ); DBG("netmask = %s\n", ip_ntoa(&addrs->netmask) ); DBG("dns1 = %s\n", ip_ntoa(&addrs->dns1) ); DBG("dns2 = %s\n\n", ip_ntoa(&addrs->dns2) ); isPPPConnected = 1; } else { // вот сюда попадаю в какой-то момент при попытке установить // TCP соединения DBG("PPP connection was lost\n"); isPPPConnected = 0; } } Сейчас хочу посмотреть, какая именно ошибка (errCode) у меня появляется, а не просто отсутствие ошибки.

Grigorij 0 26 октября, 2016 Опубликовано 26 октября, 2016 · Жалоба После почти месяца изучения LWIP проблема нашлась. Все дело оказалось в 1) некорректной настройке самой библиотеке 2) некорректной передачи данных в TCPIP Thread. В конечном итоге данные на сервер благополучно ушли. Попутно выяснилось, что версия 2.0 библиотеки несколько более дружелюбна с точки зрения поднятия PPP Over Serial Line и TCP поверх него (скорее всего субъективное мнение, но на этой версии оказалось все проще и понятнее). Однако осталась одна проблема - не могу получить DNS от оператора. Всегда имею следующие результаты (за исключением IP адреса). [017.190] network: our_ipaddr = 10.209.46.17 [017.200] network: his_ipaddr = 10.209.46.17 [017.210] network: netmask = 255.255.255.255 [017.220] network: dns1 = 0.0.0.0 [017.230] network: dns2 = 0.0.0.0 Хотя DNS и UPD разрешены.
