When purchased as an EMK the CC2540 USB Dongle comes pre-programmed with packet sniffer SW and will thus work with the free to download Packet Sniffer PC tool from Texas Instruments. The TI BLE Stack download includes several pre-made SW examples for the CC2540 USB Dongle. The most versatile is the HostTestApp project.

The HM-10 is a small 3.3v SMD Bluetooth 4.0 BLE module based on the TI CC2540 or CC2541 Bluetooth SOC (System On Chip). The HM-10 is made by Jinan . 2/2.1 modules such as the HC-06 and HC-05. The HM-10 is controlled via AT commands which are sent over the serial UART connection. There are a host of commands, some simple, some more complex .
