Copy this prompt into your AI coding tool to triage a known DAT issue:

Use https://wearables.developer.meta.com/docs/develop/dat/knownissues/, then use the Wearables MCP endpoint https://mcp.developer.meta.com/wearables to call search_dat_docs for current DAT known issues. Inspect my symptom, platform, SDK version, Meta AI app version, firmware version, and recent logs first. Match the symptom to a known issue or rule it out, then recommend the smallest workaround or next debug step before changing code. Include the exact local or device check that would verify the workaround.

Wearables Device Access Toolkit

Issue	Workaround
Device Access Toolkit Wearables App installation fails if the device battery is below 10%.	Charge your glasses until the battery level exceeds 10%, then try again.
Device Access Toolkit Wearables App installation may fail intermittently while setting or resetting device connections.	No current fix available. Future versions of Meta AI and Glasses firmware will include a more robust installation process.
Android SDK crashes intermittently when multiple captures are taken in quick succession on long-running streams (>1 min).	Close the device session and start a new one.
Android Device Access Toolkit Wearables App transfer may fail silently if Wi-Fi is off.	Enable Wi-Fi and try again.

Wearables Developer Center

Issue	Workaround
Beta testing: Distribution functionality requires minimum firmware v125	Update glasses firmware to v125 or higher.
Beta testing: Device Access Toolkit doesn’t currently allow for an application to have both a unique package name and a different bundle ID.	In the Wearables Developer Center, developers should set up individual applications for the iOS and Android platforms.
Beta testing: Device Access Toolkit currently doesn’t support the ‘-‘ dash character in the iOS Bundle ID.	Don’t use this character in the Bundle ID.
Beta testing: For v272, if the Meta AI app is connected to multiple devices, registering an app will install the Device Access Toolkit Wearables App only on one device.	All other devices will require manual installation of the DAT Wearables App from the Meta AI app.
Beta testing: New versions on Wearables Developer Center may not be compatible with apps that are not using the latest SDK and have the Device Access Toolkit Wearables App enabled.	Update your application to use the latest SDK.
Beta testing: If your application is using the latest SDK and has the Device Access Toolkit Wearables App enabled it may not be compatible with old versions on Wearables Developer Center.	Create a new version on Wearables Developer Center and push to beta testers via a Release Channel.
Email addresses of members invited to a release channel must already be associated with a Meta account.	Verify anyone you invite to a release channel has set up a Meta account at meta.ai⁠.
Users logged into developers.meta.com⁠ (Meta Horizon) may face an error with links from the Wearables Developer Center because it uses a different domain (developer.meta.com⁠).	Logout from developers.meta.com⁠ before signing up for the Wearables Developer Center.
