Phones
An iPhone or Android phone is a remote head for field work. It runs missions from the active workspace and sends its position and heading to the server. It does not edit the graph.
Allow phones
Phones need a direct HTTPS endpoint whose key they pin at pairing.
- Open Library → Phones and turn on Allow phones. This opens a phone port,
8443by default, with the server's own self-signed certificate. It is for phones only. - A server started with
--tls-self-signedon a LAN address also takes phones on its main port.
The status line reads Ready on 8443 when phones can reach the server, and Discovery on when
nearby phones can find it. Your firewall must let the port in; macOS asks the first time.
Reach the phone port over your LAN or over a Tailscale IP. Tunnels that end HTTPS, such as Tailscale Serve or a Cloudflare Tunnel, carry only the browser, never a phone.
Pair
- Press Pair phone. A QR code, an 8-digit Code and a Key appear for five minutes.
- On the phone, Scan QR. Or pick the server under Nearby and type the code. Or type
host:portand the code under Manual. - Check the phone shows the same Key, then Trust.
On a server without a browser, sdrmm phone prints the same QR code in the terminal. Use the same
--db as the running server.
Five wrong codes end the offer. Each phone gets its own token: rename or revoke the phone in the list. Revoking disconnects the phone at once.
Missions
The phone lists what the active workspace offers:
| Mission | From | Phone controls |
|---|---|---|
| Hunt | A Signal hunt wired to a channel | Start, Stop, Tune, Sweep, Mark |
| DF drive | A Direction finder and its Triangulation | Tune, Calibrate, Clear, Navigate |
| Radar | A Passive radar | None, it only shows |
| Survey | A Signal survey | Record, Stop, Clear |
A mission that cannot run is dimmed and says why, such as Not running. The phone can also switch
the active workspace. That switches it for every client.
Position and heading
Add a GPS position node, pick the Phone tab and the phone. Wire it where it is needed:
| Wire to | For |
|---|---|
Array position | Where the array stands and which way it points |
Signal hunt position | Sweep bearings with a handheld antenna |
Signal survey position | Where each level was measured |
Triangulation position | Guidance to the target |
The phone sends its pose only while a GPS node uses it. See Position and GPS.
