用CC2540 MINI DK和USB dongle做SerialApp，该怎么做？

Mini DK do not support the SerialApp becasue Mini DK cannot directly connect to a PC COM port.

While SmartRF05 Evaluation Board has RS232 logic convertion chip which can directly connect to PC COM port for the demo.

It is necessary to have two SmartRF04 + CC254xEM for the demo.

用BTOOL连接Dongle做central吗，dongle的下载程序选择哪一个？

Btool + Dongle can act as BLE Central. The firmware needed on the donlge is HostTestApp (the BLE stack can be download from TI web)

还有就是mini DK是选择SerialAppPeripheral下载吗？我下载进去过后，用BTOOL没法收索到MINI DK。。。。

You can program/flash any BLE peripheral (keyfob, simpleBLEperipheral,...) code if you want to use Btool+dongle to act as Central to scan the device.

Again, you will need to program/flash the HostTestApp into the dongle.
