Gettings started with 52833 and 5340 EVBs

[Pret]

Hello

Just purchased and received the DKs of 52833 and 5340 to learn and develop several BT applications we have in mind. We are basically hardware guys, not software, but no problem learning and getting around. What would be the recommended start with these boards? Kind of building the simple and straight-forward BT operation in beacon mode?

I realize the 5340 is supported only by nRF Connect SDK while the 52833 can be handled in both the nRF52 and Connect SDKs. We do intend to work with 5340 alongside the 82533 for direction finding in the future, so perhaps the Connect SDK would be the better option? On the other hand, the nRF52 for the 82533 would probably easier to grasp for the beginners like us?

Should we start with SoftDevice to make the start easier?

Also, I understand while starting it is worth installing the nRF Connect app into the smartphone to observe the transmissions of the EVB?

Thank you

Alex

Hi,

Direction finding is only supported in NCS so you should go with that. I would also recommend starting with our 4-part Getting Started tutorial series for NCS if you don't have any experience with Zephyr. Next, you should do the Getting started tutorial on BLE custom service for nRF5340. The Online documentation for nRF Connect SDK is also a good resource.

Also, I understand while starting it is worth installing the nRF Connect app into the smartphone to observe the transmissions of the EVB?

Yes!

Thank you Jared

I'm following the 4-part Getting Started tutorial. Up to part 2.2.2 all went exactly as per the tutorial, however at the step 2.2.2 the things do not behave exactly as expected according to the tutorial. I followed step by step and still what I get is not what is described.

I work with 5340DK board. According to the procedure in 2.2.2, once following the text and re-flashing the fresh "Hello World" as per step 1.2, I obtain the only log:

*** Booting Zephyr OS build v2.4.99-ncs1  ***
Hello World!

but there is no logs of Secure/nonsecure settings of flash, SRAM, and the peripherals as should be expected.

when I add spm.conf to the project directory as per the text and recompile/burn - nothing changes at the serial output, no matter whether the setting CONFIG_SERIAL=n or CONFIG_SERIAL=y

furthermore, the prj.conf also has CONFIG_SERIAL and no matter its settings (y or n) = it still prints out the log:

*** Booting Zephyr OS build v2.4.99-ncs1  ***
Hello World!

what do I miss here ?

Thank you

Hi there Alex!!

Sorry for the lack of reply, but I've been out of office lately. It seems that you managed to complete the tutorial?

Hi Jared, thank you for your response

Yes, I followed all the steps. Pretty clear and thorough for a novice like me. Would not say I understood everything from the software perspective (and probably this tutorial is not intended to teach how exactly to build BT stuff) but even those 5% I did already gave me some general scope...

Jared, is the similar beginner's tutorial for building BT stuff with 52833 DK  with nRF Connect SDK ?

Our future product evolves both sides of custom BT endpoints, one will probably be based on 5340, the other on 52833. So once I've tasted the 5340, I'd like to get the very basics with 52833..

Hi.

We don't have a blog type tutorial, but we do have a getting started site for the RF52 series. This along with the documentation on infocenter should be a good start.
