大家好，

目前正在跟着这个链接

学习BLE stack, 开发板是cc2650stk。虽然上面写了是针对cc2640, 但也说了cc2650stk也可以用。目前卡在

Task 2 – Connect and navigate exposed services

在使用BLE Device monitor显示HCI link error和No response from BLE host device at COM8。这个COM8在device manager中是XDS110 Class application/user uart (COM8)。请问要如何解决才能使用BLE Device monitor监测，就是完成这个TASK2。

YiKai Chen：

你是要用CC2650STK +CC-DEVPACK-DEBUGGER 來連接BLE device monitor?有沒有在CC2650STK 上執行HostTest?

Viki Shi：

请按照文档操作：

You will now program a second board with the HostTest project. The HostTest project allows a user to call most of the GAP, GATT and ATT functions of the BLE stack via a serial interface.

Susan Yang：

您给出的链接内说明了这个实验是针对CC2650 Launchpad的

The lab session targets the CC2650 Launchpad development kit, but project files are provided for CC2650 SensorTag and CC2650 Evaluation Module for SmartRF06 Evaluation Board.

关于BLE_Device_Monitor和CC2650 SensorTag 的连接，您可以看一下
