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 emitting voice LC headers in front of a packet data transmission.

TX_START_1/3/5 always sent three Voice LC Headers built from the radio's own DMR ID,
|
|
which is correct for a voice call but pollutes the air before an SMS: the receiving
|
|
end logs them as "RF user <id> rejected for using TG 0". When the queued frame is a
|
|
data burst we send standard Idle data bursts instead - a legitimate filler that
|
|
receivers discard silently.
