The error is \"Cannot read properties of undefined (reading 'requestDevice')\" which occurs at a specific timestamp [10:44:36].\n\nBased on the research provided, this error typically means that `navigator.bluetooth` is undefined. The research indicates several common causes:\n\n1. The page is not being served over HTTPS (insecure context) - this is a key requirement for Web Bluetooth API\n2. Chrome flags might need to be enabled\n3. There could be underlying Bluetooth adapter issues on Arch Linux\n4. Kernel-related problems on Arch Linux\n\nI should provide a comprehensive debugging guide that addresses all these potential issues. I'll organize it as a step-by-step troubleshooting guide, starting with the most common issues (HTTPS/secure context) and progressing to more system-level debugging.\n\nLet me structure this clearly with numbered steps and provide specific commands where applicable for Arch Linux.\n\n</details>\n\nThe error \"Cannot read properties of undefined (reading 'requestDevice')\" indicates that `navigator.bluetooth` is undefined in Chrome. This typically occurs when the Web Bluetooth API is unavailable or not properly configured. Here's how to debug this on Chrome Arch Linux:\n\n## 1. Verify Secure Context (HTTPS Required)\n\nThe Web Bluetooth API only works in secure contexts. Ensure your page is served over:[^3][^1]\n\n- **HTTPS** (production)\n- **localhost** or **127.0.0.1** (development)\n\nTo check in Chrome DevTools Console:\n```javascript\nconsole.log(window.isSecureContext); // Should return true\nconsole.log(navigator.bluetooth); // Should not be undefined\n```\n\n## 2. Enable Chrome Flags\n\nIf the API is still undefined, enable the necessary experimental features:\n\n1. Navigate to `chrome://flags` in your browser\n2. Search for and enable:\n - **Experimental Web Platform features**\n - **Web Bluetooth** (if available as a separate flag)\n3. Restart Chrome\n\n## 3. Check Bluetooth Service on Arch Linux\n\nVerify that the Bluetooth service is running:\n\n```bash\n# Check service status\nsystemctl status bluetooth\n\n# If not running, enable and start it\nsudo systemctl enable bluetooth\nsudo systemctl start bluetooth\n```\n\n## 4. Verify Bluetooth Adapter Detection\n\nConfirm your Bluetooth adapter is detected:[^4][^5]\n\n```bash\n# Check if adapter is detected\nbluetoothctl list\n\n# Check kernel recognition\nlsusb | grep -i bluetooth\ndmesg | grep -i bluetooth\n```\n\nIf no adapter is detected, you may have a hardware or driver issue.\n\n## 5. Check Chrome Browser Permissions\n\nEnsure Chrome has necessary permissions:\n\n```bash\n# Check if bluez package is installed\npacman -Q bluez\n\n# If not installed\nsudo pacman -S bluez bluez-utils\n```\n\n## 6. Kernel-Related Issues\n\nBluetooth on Arch Linux can be affected by kernel updates:[^2]\n\n- Try booting with an LTS kernel if available\n- Check for recent kernel updates that might have caused the issue\n- Consider downgrading to the previous kernel version if the problem started after an update\n\n## 7. Test with Simple Code\n\nVerify the API is accessible:\n\n```javascript\nif ('bluetooth' in navigator) {\n console.log('Web Bluetooth API is available');\n navigator.bluetooth.requestDevice({ acceptAllDevices: true })\n .then(device => console.log('Device:', device))\n .catch(error => console.error('Error:', error));\n} else {\n console.error('Web Bluetooth API is not available');\n}\n```\n\nIf the API is still undefined after these steps, the issue is likely related to either the secure context requirement or Chrome not recognizing your Bluetooth adapter properly.","profile":{"id":null,"name":null,"model":"claude-4-sonnet-thinking","model_name":"Claude 4.5 Sonnet (reasoning)","model_provider":"anthropic","model_input_limit":1000000,"recommended":false,"model_info":"\n\n\n\n<div class=\"heading\">\n <div class=\"left\">\n \n \n \n <svg class=\"model-icon icon-xs\" data-model=\"claude-4-sonnet-thinking\">\n <use href=\"#icon-anthropic\"/>\n </svg>\n <h3>\n \n <span class=\"model-provider\">Anthropic</span>\n \n <span class=\"model-name\">none</span>\n </h3>\n </div>\n\n \n <a href=\"/settings?p=custom_assistant&id=none\">\n <svg class=\"icon-sm edit-icon\" aria-hidden=\"true\">\n <use href=\"#icon-pencil\" />\n </svg>\n </a>\n \n</div>\n\n\n<hr />\n<ul>\n \n <li>\n <h4>\n Cost\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Relatively expensive\">\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --medium\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --medium\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --medium\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --medium\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-cost --medium\"></div>\n \n \n </div>\n</span>\n </li>\n <li>\n <h4>\n Quality\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Rated 4 out of 5\">\n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n </div>\n</span>\n </li>\n <li>\n <h4>\n Speed\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Rated 2 out of 5\">\n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n </div>\n</span>\n </li>\n <li>\n <h4>\n Privacy\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Rated 4 out of 5\">\n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n </div>\n</span>\n </li>\n <li class=\"divider\" aria-hidden=\"true\"></li>\n <li>\n <h4>Last updated</h4>\n <span class=\"date\">\n \n \n 2025-09-29\n \n \n </span>\n </li>\n \n</ul>\n","model_provider_name":"Anthropic","internet_access":true,"personalizations":false,"shortcut":null,"is_default_profile":false},"metadata":"<li>\n <span class=\"attribute\">Model</span>\n <span class=\"value\"><i class=\"icon-xs mr-2\"><svg><use href=\"#icon-anthropic\"></use></svg></i>Claude 4.5 Sonnet (reasoning)</span>\n</li>\n<li>\n <span class=\"attribute\">Version</span>\n <span class=\"value\">claude-sonnet-4-5-20250929</span>\n</li>\n<li>\n <span class=\"attribute\">Speed (tok/s)</span>\n <span class=\"value\">49</span>\n</li>\n<li>\n <span class=\"attribute\">Tokens</span>\n <span class=\"value\">4,176</span>\n</li>\n<li>\n <span class=\"attribute\">Cost / Total ($)</span>\n <span class=\"value\">0.03 / 0.03</span>\n</li>\n<li>\n <span class=\"attribute\">End to end time (s)</span>\n <span class=\"value\">22.33</span>\n</li>\n<li>\n <span class=\"attribute\">Submitted</span>\n <span class=\"value\">2025-11-05 06:51</span>\n</li>\n\n","documents":[]}]
