SVXLink-HotSpot

Control your RF.Guru hotspot over Bluetooth, watch the live feed, send DTMF, and explore the live reflector map from iPhone or iPad.

HotSpot is the official mobile companion for the Analog HotSpot SVXLink platform. Pair once over Bluetooth Low Energy and the app takes over from there: read live SVXLink state, switch talkgroups, send DTMF, watch the reflector network on a real map, and keep an eye on your 4G uplink.

What you can do:

• Live state feed — callsign, frequency, current talkgroup, active and last talker, TX/RX flags, plus 4G signal bars when an LTE modem is fitted.

• DTMF & device commands — full DTMF keypad with quick buttons (status, parrot, IP-announce) and a control menu for SVXLink start / stop / restart, 4G on / off, reboot and power-off.

• Talkgroup quick-dial — buttons highlighted yellow for the talkgroups your hotspot is actively monitoring, grey for switchable ones, with a green "last heard X ago" timer on each when the live feed is on.

• CTCSS info — output tone and the full input-CTCSS → talkgroup mapping shown on the Hotspot Info screen.

• Live reflector map — OpenStreetMap-based view of every node on your reflector. Spiderfy clustering, colour-coded pins (red transmitting, green ON0 repeaters, orange nodes, blue AI-detected, grey offline), floating callsign labels on active talkers, and a glass info card on every pin tap.

• Home radius — saves your QTH from GPS and frames the map at a configurable radius (default 150 km). One-tap re-center.

• Reflector talker history — live, server-paged list of who's been on the network, sourced from the same WebSocket feed.

• Auto-everything — auto-connect to your last hotspot on launch, auto-detect WSS support per reflector domain, auto-fetch the talkgroup labels from the portal, and fall back to Bluetooth-only mode when there's no internet.

• Keep-screen-on with auto-sleep — optional, slider from 0 (never sleep) to 120 min.

• Just Works pairing — no PIN, no fuss.
