TI BT log中显示:Calibration Failure Indication. Failure Code=0x1,0x1111

问题简介:

客户售后件反馈:初次上电蓝牙和wifi能正常连接;重新上电蓝牙和wifi正常连接,播放音乐几分钟后蓝牙自动断开,搜索不到蓝牙;再次上电搜索不到蓝牙,wifi连接正常,log有rx异常上报;附件的AB7B是蓝牙断开搜索不到后才进行抓取的log;

分析提供的TI BT log中存在大量的以下log信息:

1641 10/17/18 14:53:42.908 -545:39:16.497 DC_Calibration: Calibration Status (1 - Pass; 0 - Failed) = 0, Calibrated Regions (Bitwise 3 bits) = 0

1642 10/17/18 14:53:42.908 -545:39:16.497 Calibration was stoped before it was finished. Not Finished Vector=0x0, 0x20

1643 10/17/18 14:53:42.908 -545:39:16.497 Calibration Failure Indication. Failure Code = 0x1, 0x1111

1644 10/17/18 14:53:42.921 -545:39:16.484 calibration 20 did not end successfully due to general interference, need to wait 10 ms for next calibration. Attempt No. 1

具体如附件所示,麻烦说明下该段log的意思,和产生问题的原因

注意:

芯片型号:WL1831GYFVR

以上,谢谢
