cy5677无法与LE Secure Connection配对

你好，
我的开发工具可以连接到CY5677 USB加密狗，但是当我按下“配对”按钮进入配对流（LE安全连接和JuffWork身份验证）时，它不能正常工作。
首先，CY5677发送配对请求，然后发送“配对响应”，然后“配对确认（从属）”。但是CY5677似乎没有收到“配对响应”，因为CY5677不发送“配对随机”和CysSARART弹出“AuthAgErrOrthAuthoCurtisTimeOutup”几秒钟后。
我发现奇怪的是，在我们发送“配对响应”之后，我的BLE嗅探器在下一个连接事件中显示了CY5677的“CRC错误包”。
然而，我试图把“SC点（安全连接）”0要求乐遗产配对，效果不错！
我不知道为什么发生和如何对cy5677乐安全连接正确。
谢谢！

  Hi,
    My development tool can connect to CY5677 u*** dongle, but it can't work correctly when I pressed "pair" button to enter pairing flow(LE Secure Connections and Justwork authentication).
    At first, CY5677 would send pairing request, then I send "pairing response" and followed by "pairing confirm(slave)". But CY5677 seems not to receive "pairing response" because CY5677 don't send "pairing random" and CySmsart pop up "AUTH_ERROR_AUTHENTICATION_TIMEOUT" a few seconds later.
    I found it strange that after we sent "pairing response", my ble sniffer showed "crc error packets" from CY5677 at the next connection event.
    However, I tried to set "SC bit(secure connection)" to 0 to request LE legacy pairing, it works fine!
    I don't know why happened with CY5677 and how to pair with LE Secure Connections properly.
    thanks!
