Subscribing via PTT (Push-To-Talk) + +The easiest way to subscribe to a Talkgroup is to simply **transmit** on it from your radio. + +* **Action**: Key up (PTT) on `TG 1234`. +* **Result**: The reflector detects your transmission and automatically subscribes you to `TG 1234` for the configured timeout duration (e.g., 10 minutes). +* **Renewal**: If you are already subscribed, keying up again will **reset the timeout timer** back to the full duration. +* **Note**: The first transmission might be muted (Anti-Kerchunk) to prevent noise, but you will immediately be subscribed. + +### 2. Subscribing via Options String + +You can manage subscriptions sent from your MMDVM hotspot/repeater configuration (or Pi-Star Options field). + +* **Format**: `TS1=TG_ID;TS2=TG_ID;AUTO=TIMEOUT` +* **Example**: `TS2=3100,4001;AUTO=600` + * Subscribes Timeslot 2 to TG 3100 and TG 4001. + * Sets timeout to 600 seconds. + +### 3. Disconnecting / Unsubscribing + +* **Disconnect All**: Transmit a Group Call to **TG 4000**. This clears all dynamic subscriptions on that timeslot. +* **Single Mode**: If `SingleMode=true` is set in config, transmitting on a *new* Talkgroup automatically unsubscribes you from the previous one. + +### 4. Talkgroup 9 (Reflector) + +* Traffic on **TG 9** is treated as local reflector traffic (linked functionality) if the client is essentially "linked" to a module, but in Mini DMR mode, TG 9 behavior depends on the specific map configuration or defaults. Typically, use specific Talkgroups for wide-area routing. + +## Dashboard + +The URFD Dashboard includes a dedicated **DMR** page (`/dmr`) to monitor Flexible DMR Mode activity. + +* **Active Subscriptions**: Shows all Talkgroups a client is monitoring, along with the specific Timeslot. +* **Timers**: Displays a real-time countdown for Dynamic Subscriptions. Static subscriptions are marked as `Static`. +* **DMR ID**: Displays the client's DMR ID alongside their callsign (e.g., `CALLSIGN (3100123)`). +* **Requirements**: The dashboard requires NO additional configuration. It automatically displays data once `XlxCompatibility=false` is set in the backend config. + +## Troubleshooting + +### "Recordings are blank" or "No Traffic on other modes" + +If clients can connect and transmit but you see no traffic on other protocols (M17, YSF) or blank recordings: + +* **Check Modules**: Ensure the mapped Module (e.g. A for TG 4001) is defined and **enabled** in your `[Modules]` configuration. +* **Log Check**: Look for `Can't find module 'X' for Client ...` errors in the reflector log. diff --git a/docs/MINIDMR_Architecture.md b/docs/MINIDMR_Architecture.md new file mode 100644 index 0000000..c947be3 --- /dev/null +++ b/docs/MINIDMR_Architecture.md @@ -0,0 +1,184 @@ +# Investigation and Fix Plan: Flexible DMR Mode + +## Problem Description + +User wants to support two modes of operation for DMR: + +1. **XLX Mode** (Default): Legacy behaviors.
