Я пытаюсь сделать одноранговую Javascript игру, в которую можно играть в мобильных браузерах.
- Мне удалось успешно установить p2p-соединение между двумя телефонами в моем локальная сеть WiFi.
- Я не могу подключить два телефона по мобильным сетям или один по WiFi и один по мобильной сети.
- Я попытался отключить брандмауэр Windows и не смог подключиться мой P C на мой телефон в мобильной сети.
- Я попытался заставить обоих пиров настроить свои собственные каналы данных и установить согласование.
Я прочитал это 80% до 90% устройств могут подключаться через WebRT C без серверов TURN, поэтому я совершенно не понимаю, что делать дальше.
