Восстановлено из транскрипта сессии после потери рабочего дерева на сервере сборки. Что внутри: - четыре новых модуля прошивки (приём, сборка исходящего, меню Messages); - правки существующих файлов в виде скриптов, с порядком применения; - инструменты стенда: снятие экрана рации по USB, дамп кадров, эталонная сборка пакета; - NOTES.md: что проверено в эфире, что не доделано, где грабли. Работало в эфире в августе 2026: данные ходят в обе стороны в режиме хотспота, рация принимает SMS и показывает на экране. Отправка собрана и сверена с эталоном сервера побайтово, но в эфире не проверялась. Claude-Session: https://claude.ai/code/session_01GJtvG5WwqYNe1b7s9LLtgy

"""Stop the radio from dropping out of hotspot (modem) mode when the host goes quiet.
|
|
|
|
Stock behaviour: if the USB host does not talk to the radio for MMDVMHOST_TIMEOUT
|
|
(20 s), the firmware calls hotspotExit() and leaves modem mode by itself. That is a
|
|
safety net for a crashed host, but it makes the radio unusable as a permanently
|
|
attached modem - which is exactly how it is used here.
|
|
|
|
With the timeout set to 0 the inactivity check is disabled; leaving modem mode is
|
|
then only done deliberately (by the user from the radio, or by the host asking the
|
|
modem to go idle).
