From 574651b9b3f567be369313126ca08666b4826010 Mon Sep 17 00:00:00 2001 From: Joshua Mesilane Date: Fri, 15 May 2026 10:06:34 +1000 Subject: [PATCH 1/8] feat: decouple radio hardware from service startup via RadioManager MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit HTTP server and web UI now always start regardless of radio hardware availability. RadioManager owns the full radio lifecycle — connection, exponential backoff retry, mid-run reconnect, and hardware cleanup — so the daemon is no longer blocked on hardware initialisation. - Add RadioManager: asyncio task with retry loop, status tracking, on_connected/on_disconnected callbacks, and /api/stats reporting - Refactor main.py: initialize() handles identity + sensors + GPS; _on_radio_connected() sets up dispatcher and all helpers; HTTP server starts before RadioManager so it is always reachable - Move LocalIdentity setup to initialize() so public key is available from boot, not only after first radio connection - Add engine.py async stop() for awaitable mid-run teardown - Remove _kiss_transport_restart_required() from config_manager; radio_type and KISS config changes now trigger automatic reconnect via notify_config_changed() instead of requiring a service restart - Fix SPI re-init bug: explicitly reset _initialized on SX1262Radio singleton after cleanup() so begin() is called on reconnect - Move CH341 and radio.cleanup() out of _shutdown() into RadioManager Co-Authored-By: Claude Sonnet 4.6 --- .gitignore | 3 + repeater/config_manager.py | 38 ++---- repeater/engine.py | 10 ++ repeater/main.py | 265 +++++++++++++++++++++---------------- repeater/radio_manager.py | 264 ++++++++++++++++++++++++++++++++++++ 5 files changed, 439 insertions(+), 141 deletions(-) create mode 100644 repeater/radio_manager.py diff --git a/.gitignore b/.gitignore index 4cacd56c..883e020f 100644 --- a/.gitignore +++ b/.gitignore @@ -62,6 +62,9 @@ data/ *.log .DS_Store syncpi.sh +RULES.md +PROBLEM_STATEMENT.md +PR_DESCRIPTION.md # Docker /data diff --git a/repeater/config_manager.py b/repeater/config_manager.py index 56cb05e9..df1d0b6a 100644 --- a/repeater/config_manager.py +++ b/repeater/config_manager.py @@ -48,28 +48,6 @@ def _sync_repeater_handler_radio_config(self, radio_cfg: Dict[str, Any]) -> None } ) - def _kiss_transport_restart_required(self) -> bool: - radio = getattr(self.daemon, "radio", None) - kiss_cfg = self.config.get("kiss", {}) or {} - if radio is None or not kiss_cfg: - return False - - runtime_port = getattr(radio, "port", None) - runtime_baudrate = getattr(radio, "baudrate", None) - - configured_port = kiss_cfg.get("port") - configured_baudrate = kiss_cfg.get("baud_rate") - - if configured_port and runtime_port and str(configured_port) != str(runtime_port): - logger.info("KISS port change detected;
