Is the Enhanced ShockBurst (ESB) protocol applicable to the nRF5340?

[ParanBada]

Hi, Good afternoon. Some Questions.

1.

Is the Enhanced ShockBurst (ESB) protocol applicable to the nRF5340?
I'd appreciate it if you could give me details on how to get started.

2.

Where can I download the example source code that can be used in the nRF5340?
I searched and found something called nRF_Connect_SDK, is this here?
Is there an ESB example source code that I can use for the nRF5340?

3.

The nRF5340 had two built-in Network Processor and Application Processor.
Then, do I develop the firmware separately and download two?

More help please, thank you.

Regards,

SB YIM

Hi,

 

To start with the nRF5340, you need to install nRF connect SDK, which can be done through the "nRF Connect for desktop", application "toolchain manager":

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.0/nrf/getting_started.html#

Once the toolchain manager is installed, you can follow this guide which is specific to the nrf5340dk:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.0/nrf/ug_nrf5340.html 

  

Yes, the nrf_esb library can be built with the nRF5340 network core board:

https://github.com/nrfconnect/sdk-nrf/blob/master/samples/esb/

 

 

The nRF5340 had two built-in Network Processor and Application Processor.
Then, do I develop the firmware separately and download two?

The application cpu must be programmed first, because this cpu core enables the network core.

You then compile and load this project for board nrf5340dk_nrf5340_cpuapp:

https://github.com/nrfconnect/sdk-nrf/tree/master/samples/nrf5340/empty_app_core

 

Then you load the wanted ESB sample for board "nrf5340dk_nrf5340_cpunet".

 

Kind regards,

Håkon
