ble不能正常通讯

你好： 我是翼动通讯的工程师，在使用2540和2541的过程中遇到一下三个问题，请帮忙。

1、iphone端的app连接三个以上keyfob，在iphone走远直至连接断开，过10分钟后走进keyfob。这时能连接上，因为我们keyfob是以1秒的间隔广播数据包。但是其中有2个或1个不能与app正常通讯，但是app显示所有的keyfob都连接成功。

2、我司现在要生产10K的2541，请问如何校准频偏？除了频偏还需要做那些测试？

3、我现在需要在2541或者2540的协议栈里面添加代码，代码的功能是实现丢包率的测试，请问有那些api可以使用？能不能给我一个例程？

    1. Please explain in more details in your testing sequence

    2. If you are using +/-10ppm 32Mhz crystal. There is no need to tune the freq.
    Or, we do support those HCI Vendor Specific command for freq tunning. Please refer to "TI_BLE_Vendor_Specific_HCI_Guide.pdf"

    3. Again we do support those HCI Vendor Specific command for packet error rate test. With BLE instruments such as Anritsu, it can be tested automatically.
