Hello world: ble_A_Hello_World_Program. Can you give your important feedback from screenshot I attached? I am also trying to figure out from my end.

The SDK includes a number of examples - which one are you using?

I connected module to arduino uno board via SPI connections. Also provided 3.3V to module. I am running SDK code from the link you have sent in your previous answer. Its working. But still, In serial monitor I am not receiving BLE advertising confirmation response, which is "Advertising started : Tap Connect on the nRF UART app" according to arduino SDK code. BLE is still undiscoverable in nordic android app. I have attached screenshot of my serial monitor response in my question. As Arduino SPI voltage level is 5V. I am using LM1117 ICs to downgrade it to 3,3V (Mod-nRF8001 Module SPI level). Is it correct or should I use resistor voltage divider circuit only?. Do I need to connect arduino reset pin to module reset pin? Please guide me.

Like I said, "it needs an external 'host' (eg, a microcontroller) to make it actually do anything"

And, yes, the host must be connected via SPI and will need to be running suitable code; eg, built on the SDK.

Yes this one only I bought. Yeah I know Its a transceiver. So thats what I am asking. Like normal Bluetooth modules, will it be power on & discoverable , once I provide 3.3V supply. OR It reaquires SDK & SPI host connections to start advertising.

I take it you mean this:

Note that the nRF8001 is just a radio transceiver - it needs an external "host" (eg, a microcontroller) to make it actually do anything.

There is an Arduino SDK: github.com/.../ble-sdk-arduino
