SimpleBLEPeripheral 与dongle自动断开连接后再也无法重连

TI的工程师，你好

我使用CC2640作为从机和dongle配对连接后，一段时间以后会出现自动断开的情况（CONNECTION_TIMEOUT），之后dongle在也无法连接CC2640（CONNECTION_FAILED_TO_BE_ESTABLISHED）。这可能是由于什么原因导致的？

log及sniffer抓图如下：

Derrick Cheng，

能把完整的空中log附件上来吗？

包括自动断开的，还有连接失败的。

谢谢回复，

上次抓到的log没有保存，在抓到后我会及时上传。

另，sniffer 经常抓不到想要的数据是什么原因呢？ 比如filter配置为PTZ=L2CAP-S PTZ=Control  但即使有连接还是没有抓到任何包

Y，

连接不上的过程抓不到任何包，不知道是因为sniffer的原因还是别的，

dongle 提示信息是：

CONNECTION_FAILED_TO_BE_ESTABLISHED

这个问题之前也有人提过，https://e2e.ti.com/support/wireless_connectivity/bluetooth_low_energy/f/538/t/377682

• The RF performance on one or both devices is not good, so the slave either never receives the connection request, or the master never receives any packets from the slave during the first 6 connection events. The RF Performance could be bad due to a failed CRC, collision or maybe the devices are just out of range. dongle 显示RSSI -34db，可以排除
• There could be a timing issue in either device. If the link layer clock on either device is not running at 32.768kHz (within the tolerance set using the HCI_Ext_SetSCACmd function; default is +/-50ppm) then the timing will be off and the slave might not be listening at the correct time to receive the master's packets. PM2会用到32.768K的晶振？
• If the slave device is advertising with the whitelist filter policy set to GAP_FILTER_POLICY_WHITE_CONor GAP_FILTER_POLICY_WHITE then the slave will ignore the connection from the master and continue advertising normally, and the master will get the 0x3E error since it does not receive any packets from the slave during the first 6 connection events. 白名单没有配置，使用默认值

另外 ，这么两个现象：

1. 连接不上的情况大多发生在使用串口下载firmware以后（rom bootloader）

2. 重启很多次以后有改善，可以正常连接

接上贴，

以下是联系很多次尝试连接后dongle的log：
