Hi, i recommend you follow wass links and look in to the platform and environment to get to know the product as he said, as for links to Bluetooth examples here are some exampelse https://github.com/nrfconnect/sdk-nrf/tree/master/samples/bluetooth

In NCS will find all the examples in this path: nrf>samples>bluetooth

Regards,
Jonathan

Thanks for links. Actually I just need a bluetooth example that make my nRF5340 discoverable over BLE for my project. I am building a project where I want my nRF5340, connect to a gateway (RPi) over BLE. For RPi I could write code I have already done this with Arduino+BLE module. I want to make it work with nRF5340 as it is be battery powered which fulfills my requirement.

For nRF5340, this is where you can get started
https://infocenter.nordicsemi.com/index.jsp?topic=%2Fstruct_nrf53%2Fstruct%2Fnrf5340.html
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/getting_started.html

I can keep posting link, but you can also take the time to explore all the doc first, I know it's overwhelming but you need to take the time, not sure what your goal is, just learning as a hobby or you need to finish a school project, the approach is different.

Ok thanks. Is the source code for the Heart Rate Monitor (HRM) demo application available as described in link infocenter.nordicsemi.com/index.jsp

In the ticket I mentioned there was a detailed explanation with a link to the bluetooth sample.
If you're not familiar with the SDK, the first thing to do would be to take the time to explore it and figure out which samples it has and how to compile them with which target.
Now when it comes to the Raspberry pi, it no longer relates to which uC you're using as Bluetooth is a standard, so you might find more help on either of Raspberry pi forums or standard linux bluetooth applications depending on the distribution you're using.

I also recommend first to get familiar with bluetooth and GATT by following some tutorials web/video or existing books or courses.
here's an example learn.adafruit.com/.../gatt

Thanks for reply. Yes, RPi has bluetooth. Please provide link to code/example for nrf5340 and RPi (i.e. how to accept data in RPi).

If your RPi has support for Bluetooth then you can use that to communicate between the two devices. Like wass proposed.

If you meant through the air with rf then you can also use Bluetooth from nRF5340 to raspberry pi.

See the discussion here devzone.nordicsemi.com/.../how-to-send-string-message-from-nrf52840-to-raspberry-pi

Alternatively, you could use openthread, which has the advantage of being able to send messages to every internet device not only the raspberry pi, then you'd need a dongle such as the nRF52840 Dongle.
