TI Tutorial :
http://processors.wiki.ti.com/index.php/Tutorial:_How_to_Create_a_Custom_Bluetooth_Smart_Embedded_Application_with_the_CC2650DK

define 128-bit UUID : F000-EE00-0451-4000-B000-000000000000
define Characteristic 1 Properties : Read
define Characteristic 2 Properties : Write / Notify
define Characteristic 3 Properties : Read

1.Advertising Packet

2.Central(Android phone) connection with CC2541

3.Check characteristic properties

4.Read characteristic 1 default value

5.Peripheral (CC2541) set characteristic 1 value:

6.Read characteristic 1 Value

7.Central (Android phone ) write data to peripheral (CC2541) 

8.Peripheral (CC2541) receive the write data

9.Enable Notification

10.Peripheral (CC2541) send notification data to central (Android phone )  

11.Central receive the notification data

12.Read characteristic 3 default value

13.Peripheral (CC2541) set characteristic 3 value

14.Read characteristic 3 value

Android 6.0 as BLE Peripheral and CC2541 as BLE Central

1.Android5.0 and Android6.0 BLE Check.

Android 5.0 support central mode only!!

Android 6.0 support central mode and peripheral mode !!

2.Android 5.0 phone as central / Android 6.0 phone as peripheral .

Connected with peripheral device.

3.Check service,attribute and peripheral notify data to central .

4.Program TI-BLE-CC254x-1.4.1 CC254x_SmartRF_SimpleBLECentral.hex

CC2541 discovering ....



Can't find !!

5.Modify source code and try again.

CC2540 / CC2541 White List Test

CC2540 / CC2541 Android Phone White List Test

Get BLEPeripheral_WL Device MAC

Android Phone Scan

Use one android phone to bonding BLEPeripheral_WL

Enable White List Function

White List Function define：Allow Scan Request and Connect from White List Only

Android Phone Re-Scan

Disable White List Function

Android Phone Re-Scan

CC2540 / CC2541 Modify The Maximum Number Of Bonds to 25

CC2540 / CC2541  Modify The Maximum Number Of Bonds to 25

CC2540 / CC2541  Maximum Number Of Bonds default : 10

1. Add USART command and function to get bonding info

CMD_PERIPHERAL_GET_BOND_INFO

Return

Maximum Number Of Bonds default : 10, Unbonds BOND.MAC return：FF FF FF FF FF FF

2. Add one bonding device and check the bonding info. 

3.Modify the TI-BLE-CC254x BLE-Stack source code & add bonding device to bonding id:25
