Integrating with Stratux

Stratux is not "GDL90 over UDP and nothing else." It simultaneously offers several output transports plus a couple of inbound ones, so an EFB/EFIS/app can pick whatever fits. This page is the map; the linked docs have the detail.

Transport map

Transport Port / path Payload Direction Typical consumer
GDL90 UDP :4000 GDL90 (binary) push → DHCP-lease + StaticIps clients ForeFlight and most EFBs
GDL90 WebSocket /gdl90 GDL90 (binary) push to connected WS client web UI, browser apps
FLARM / NMEA UDP :2000 $PFLAA/$PFLAU/$GPRMC/… push → DHCP-lease clients EFIS, FLARM-aware apps
FLARM / NMEA TCP :2000 same NMEA client dials in AirConnect-style apps
FLARM / NMEA serial (/dev/serialout*) configurable (default NMEA) push over wire panel EFIS
FLARM / NMEA Bluetooth LE (GATT) same NMEA push to paired device BLE EFBs, SoftRF-style apps
X-Plane / FF-sim UDP :49002 GPS + attitude + traffic datagrams push → DHCP-lease clients SkyDemon, X-Plane
Cursor-on-Target UDP :8087 CoT XML inbound ATAK (injects traffic)
NMEA in TCP :30011 NMEA inbound external OGN tracker feeding data in
HTTP / WebSocket JSON TCP :80 JSON request / stream any tool, see below

Details:

  • gdl90.md — the GDL90/UDP protocol, how to recognize Stratux, sleep mode, traffic lifecycle, ForeFlight specifics.
  • other-transports.md — FLARM/NMEA (TCP/UDP/serial/BLE), X-Plane, Cursor-on-Target, and the Capability bitmask.
  • http-api.md — the full HTTP + WebSocket JSON API (status, situation, traffic, weather, settings…).
  • settings-reference.md — every setting, including the output configuration (NetworkOutputs, SerialOutputs, BleOutputs).

How outputs are selected: the Capability bitmask

Each output (a networkConnection, serialConnection, or bleConnection) carries a static Capability bitmask that decides which classes of message it receives. There is no runtime capability negotiation with the client — the bits are fixed per output. Values:

Bit Value Meaning
NETWORK_GDL90_STANDARD 1 Standard GDL90 messages
NETWORK_AHRS_FFSIM 2 AHRS in ForeFlight-sim (X-Plane) format
NETWORK_AHRS_GDL90 4 AHRS as the GDL90 0x4C message
NETWORK_FLARM_NMEA 8 FLARM/NMEA sentences
NETWORK_POSITION_FFSIM 16 Position in ForeFlight-sim (X-Plane) format

So the three default UDP outputs are :4000 = 1|4 = 5 (GDL90 + GDL90-AHRS), :2000 = 8 (FLARM/NMEA), and :49002 = 2|16 = 18 (X-Plane position + attitude). ForeFlight-sim outputs also force one message per UDP packet.

Networking basics

  • Default Stratux IP is 192.168.10.1 in AP mode (the DHCP-assigned address in client mode).
  • No authentication — it is a local AP network, HTTP not HTTPS.
  • UDP push outputs send to every device holding a DHCP lease, plus any StaticIps.
