如何從智能手錶獲取Google Fit數據可穿戴設備Fossil Q Founder？哪些符合BLE要求？ Android

Question

我試圖通過Google Fit Android SDK從英特爾的基於Fossil Android的Smartwatch（BLE設備）中提取數據。 BLE掃描似乎發生，配對發生，但在結果內部回調它不會去onDeviceFound（如果它到達，我可以從那裏繼續）。它在掃描開始的幾秒鐘內最終會超時。

任何幫助，將不勝感激。

感謝您的文檔鏈接。我確實經歷了所有這些，但沒有幫助。這是我的Class文件，我可以從我的MainActivity調用startBleScan，BleScan似乎正在工作，但在此之後，它不會繼續執行onDeviceFound方法。
