Do you use SensorTag App on Android to scan your CC2540 BLE peripheral ?

Thanks ykn

Load SimpleBLEBroadcaster code in cc2540 and able to show device TI androis app as simple ble broadcaster.

But i can not able to connect with CC2540 and Android BLE.

Want to transmit packet from CC2540 and capture or observe on android device.

Which is proper code for that functionality Try by using ble peripheral but can not show CC2540 in Android app or not detect or search CC2540 in BLE device.

and what is difference between ble peripheral and ble central and ble observe and so on???

A BLE boradcaster cannot be connected. If you need to connect to BLE device, you should use peripheral role on BLE device.

Which CC2540 EVB do you use? I just test SimpleBLEPeripheral on my SmartRF05-CC2541EM and it works fine.

use Custom design of ECG Application in my design Use ADS1293 chip, MPU9150 and wifiESP8266 also RF part for Bluetooth.

Read ADS using SPI and MPU using I2C by CC2540 and also success to send data over wifi using ESP8266.

Next want to same data send on Bluetooth and receive by BLE android Device.

Use BLE peripheral example on CC2540 from BLEstack but can not search or find CC2540 as BLE in BLE device(Android Phone)

when use broadcaster example its success as broadcaster..so what is issue??

Braodcaster is work fine but peripheral or other example not work or not find CC2540 as BLE.

I suggest you to use sniffer to check if your BLE device does advertising.
