TTC BLE CC2640 SDK 2.0.0 main features are as follows:
    The TTC SDK V2.0 version adds a richer example of the Bluetooth role, which also includes two combinations of modes. Users can use the relevant AT command to complete the function of different roles control, can be more efficient to complete the Bluetooth host, slave and other role development.

The SDK role contains the following four types:
1. Slave mode
2. Slave + observer combination mode
3. Host mode
4. Host + broadcast combination mode

Complete the basic operation through the AT command :

1. Peripheral
(1) to open the broadcast
(2) turn off the radio
(3) to send data to the host
(4) disconnect the host

2. slave + observer
(1) broadcast scan
(2) to open the broadcast
(3) turn off the radio
(4) to send data to the host
(5) disconnect the host

3. host
(1) scanning equipment
(2) Connect the device
(3) to send data to the slave
(4) Disconnect from the slave

4. Host + broadcast
(1) scanning equipment
(2) Connect the device
(3) to send data to the slave
(4) Disconnect from the slave
(5) open broadcast (not linkable)
(6) turn off the radio
