The pinned DAT SDK 0.4.0 only supports Ray-Ban Meta firmware up to ~V20-V22 (per Meta's Version-Dependencies matrix). Newer glasses (e.g. the 2026 frames running V125-generation firmware, DAT runtime 0.7.0.10.0) are never discovered: registration succeeds and audio works, but devicesStream stays empty, AutoDeviceSelector never emits, and requestPermission(.camera) throws .noDevice. Reported widely (issues #200, #207, #201). This migrates the app to DAT SDK 0.7.0 and its session-based device model: - pbxproj: meta-wearables-dat-ios 0.4.0 -> 0.7.0 - StreamSessionViewModel: migrate StreamSession -> wearables.createSession( deviceSelector:) -> DeviceSession; wait for session .started before session.addStream(config:) -> MWDATCamera.Stream (addStream returns nil if the session hasn't connected yet, matching Meta's own 0.7.0 sample); remap the renamed StreamState/StreamError/StreamConfiguration types - WearablesViewModel: request camera permission as soon as registration completes (the device does not appear in devicesStream until a permission is granted via Meta AI; the stock flow only requested it behind the Start-streaming button, which is disabled until a device appears -- a deadlock) - Info.plist: add the 0.7.0 discovery keys from Meta's sample -- bluetooth-central + processing background modes, NSBonjourServices (_bonjour._tcp), NSLocalNetworkUsageDescription Tested live: glasses camera POV streams end-to-end on a Ray-Ban Meta (V125-gen firmware, iOS 26.5).

Problem
On newer Ray-Ban Meta glasses (2026 frames running V125-generation firmware, DAT runtime
0.7.0.10.0), VisionClaw can pair and play audio, but the camera never streams: registration reaches.registered, yetdevicesStreamstays empty forever,AutoDeviceSelector.activeDeviceStreamnever emits, andrequestPermission(.camera)throws.noDevice. So "Start streaming" is permanently disabled.Root cause: the pinned
meta-wearables-dat-ios0.4.0 only supports Ray-Ban Meta firmware up to ~V20–V22 (per Meta's Version Dependencies matrix). V125-generation glasses need SDK 0.7.0. Reported widely upstream: facebook/meta-wearables-dat-ios#200, #207, #201.The fix
Migrates to DAT SDK 0.7.0 and its session-based device model (introduced in 0.6.0):
meta-wearables-dat-ios0.4.0 → 0.7.0.StreamSession→wearables.createSession(deviceSelector:)→DeviceSession; grabstateStream()beforestart(), wait until the session reaches.startedbeforesession.addStream(config:)→MWDATCamera.Stream(addStreamreturns nil if the session hasn't connected yet — matches Meta's own 0.7.0 sample); remap the renamedStreamState/StreamError/StreamConfigurationtypes.devicesStreamuntil a permission is granted via Meta AI, but the stock flow only requested it behind the Start-streaming button — which is disabled until a device appears. That's a deadlock on devices that don't auto-grant.bluetooth-central+processingbackground modes,NSBonjourServices(_bonjour._tcp), andNSLocalNetworkUsageDescription.Testing
Tested live on hardware: glasses camera POV streams end-to-end into the Gemini pipeline on a Ray-Ban Meta (V125-gen firmware, iOS 26.5). Scope is intentionally minimal — only the DAT migration; no behavior change to the Gemini/OpenClaw paths.
Older glasses on 0.4.x firmware: worth a maintainer check, but 0.7.0 is Meta's current SDK and the matrix lists it as the supported path going forward.
