# iOS Node Connection Runbook (Iris)
|
||
|
||
This is the practical “how do I connect Iris” guide:
|
||
|
||
**iOS app** ⇄ (Bonjour + TCP bridge) ⇄ **Gateway bridge** ⇄ (loopback WS) ⇄ **Gateway**
|
||
|
||
The Gateway WebSocket stays loopback-only (`ws://127.0.0.1:18789`). Iris talks to the LAN-facing **bridge** (default `tcp://0.0.0.0:18790`) and uses Gateway-owned pairing.
|
||
|
||
## Prerequisites
|
||
|
||
- You can run the Gateway on the “master” machine.
|
||
- Iris (iOS app) is on the same LAN (Bonjour/mDNS must work).
|
||
- You can run the CLI (`clawdis`) on the gateway machine (or via SSH).
|
||
|
||
## 1) Start the Gateway (with bridge enabled)
|
||
|
||
Bridge is enabled by default (disable via `CLAWDIS_BRIDGE_ENABLED=0`).
|
||
|
||
```bash
|
||
pnpm clawdis gateway --port 18789 --verbose
|
||
```
|
||
|
||
Confirm in logs you see something like:
|
||
- `bridge listening on tcp://0.0.0.0:18790 (Iris)`
|
||
|
||
## 2) Verify Bonjour discovery (optional but recommended)
|
||
|
||
From the gateway machine:
|
||
|
||
```bash
|
||
dns-sd -B _clawdis-bridge._tcp local.
|
||
```
|
||
|
||
You should see your gateway advertising `_clawdis-bridge._tcp`.
|
||
|
||
If browse works, but Iris can’t connect, try resolving one instance:
|
||
|
||
```bash
|
||
dns-sd -L "<instance name>" _clawdis-bridge._tcp local.
|
||
```
|
||
|
||
More debugging notes: `docs/bonjour.md`.
|
||
|
||
## 3) Connect from Iris (iOS)
|
||
|
||
In Iris:
|
||
- Pick the discovered bridge (or hit refresh).
|
||
- If not paired yet, Iris will initiate pairing automatically.
|
||
|
||
## 4) Approve pairing (CLI)
|
||
|
||
On the gateway machine:
|
||
|
||
```bash
|
||
clawdis nodes pending
|
||
```
|
||
|
||
Approve the request:
|
||
|
||
```bash
|
||
clawdis nodes approve <requestId>
|
||
```
|
||
|
||
After approval, Iris receives/stores the token and reconnects authenticated.
|
||
|
||
Pairing details: `docs/gateway/pairing.md`.
|
||
|
||
## 5) Verify the node is connected
|
||
|
||
- In the macOS app: **Instances** tab should show something like `iOS Node (...)`.
|
||
- Via Gateway presence:
|
||
```bash
|
||
clawdis gateway call system-presence --params "{}"
|
||
```
|
||
Look for the node `instanceId` (commonly `ios-node` unless changed in Iris settings).
|
||
|
||
## 6) Drive the iOS Canvas (draw / snapshot)
|
||
|
||
Iris runs a WKWebView “Canvas” scaffold which exposes:
|
||
- `window.__clawdis.canvas`
|
||
- `window.__clawdis.ctx` (2D context)
|
||
- `window.__clawdis.setStatus(title, subtitle)`
|
||
|
||
### Draw with `screen.eval`
|
||
|
||
```bash
|
||
clawdis nodes invoke --node ios-node --command screen.eval --params "$(cat <<'JSON'
|
||
{"javaScript":"(() => { const {ctx,setStatus} = window.__clawdis; setStatus('Drawing','…'); ctx.clearRect(0,0,innerWidth,innerHeight); ctx.lineWidth=6; ctx.strokeStyle='#ff2d55'; ctx.beginPath(); ctx.moveTo(40,40); ctx.lineTo(innerWidth-40, innerHeight-40); ctx.stroke(); setStatus(null,null); return 'ok'; })()"}
|
||
JSON
|
||
)"
|
||
```
|
||
|
||
### Snapshot with `screen.snapshot`
|
||
|
||
```bash
|
||
clawdis nodes invoke --node ios-node --command screen.snapshot --params '{"maxWidth":900}'
|
||
```
|
||
|
||
The response includes `base64` PNG data (for debugging/verification).
|
||
|
||
## Common gotchas
|
||
|
||
- **iOS in background:** all `screen.*` commands fail fast with `NODE_BACKGROUND_UNAVAILABLE` (bring Iris to foreground).
|
||
- **mDNS blocked:** some networks block multicast; use a different LAN or plan a tailnet-capable bridge (see `docs/discovery.md`).
|
||
- **Wrong node id:** `--node` must match the node’s `instanceId` (shown in Instances/presence).
|
||
- **Stale pairing:** if the token is lost, Iris must pair again; approve a new pending request.
