Hi all!

Hi Toan,

You need to download the TI BLE Stack and read through the Software Developers Guide that comes included with it.

Cheers,
Fredrik

This is already done by TI CC2541 SensorTag reference design which you can refer to processors.wiki.ti.com/.../SensorTag_User_Guide

If you download and install BLE stack 1.4.1, there is a SimpleBLEPheral example that you can refer to.

You can use API HalLedBlink ( HAL_LED_1, 5, 50, 500 ) to blink LED.
