截至2015年初，chrome.bluetoothLowenergy Chrome App API 仅在Chrome操作系统上实施。 documentation在任何地方都没有提到这一点，但这是一个重要的注意事项！您可以在crbug.com上搜索bluetoothLowEnergy以查找其他因为文档未提及此事而感到困惑的人。另见问题Connecting to an iOS device using the chrome.bluetoothLowEnergy API。
要查看桌面版Chrome浏览器的实施进度，请列出以下问题之一：364359: Implement GATT API on OS X和388016: Implement the chrome.bluetoothLowEnergy API on Windows。我认为目前还没有计划在桌面Linux上支持它（尽管他们已经在ChromeOS上实现了它）。
@Xan，我创建了Issue 460741: chrome.bluetoothLowEnergy API documentation does not list supported platforms以建议更新API文档。
