Cant figure what SoftDevice I need

[etamar]

hello,

again, sorry for the begginers qustion(probablly i will have 2-3(hopefully) in the next few days). I got today the nrf52-dk, and on the back of the nrf52 is written: " n52832 QFAAB0 1611AN(on the other five nrf52 the last 3 characters are 2AP) " I cant figure out to what cattegory it belongs in the page: infocenter.nordicsemi.com/index.jsp *** from some reason this link is the same as in the next question, here i meant to the page showing :"Table 1. Documentation and reference design files overview"

• how could i knew it?
• what does the Engeneering 1\2\3 means?

in a tuturial when tring to figure what softdevice i need, the refference page is: infocenter.nordicsemi.com/index.jsp

it is Nrf51 products.

Sorry for overwriting. Thank You!

I think the softdevice number corresponds to the protocol stack you want to use: nRF52 Softdevice

And in your question you wrote that you have a nrf52-dk, but you are looking in nrf51 documentation. Its sometimes a little bit confusing.

Thank you. For my first question, That is what I meant also, look at the titles, they belong to nrf52

I don't know why the webpage mixes nRF51 and nRF52. And I'm not able to navigate to that webpage in contents.

Anyways, you have the nRF52832, a device in the nRF52 Series, the only device actually.

To figure out what revision you have you should compare the laser marking on the chip with this table.

There you can see that you have revision 1 of the chip, this is revision that is ready for production, so that's good.

Now that you know what revision you have, you can check this table to see what SoftDevice and SDK versions it is compatible with.

It is compatible with S132 v2.0.x and v3.0.0, but v3.0.0 doesn't have SDK support yet, so if you are a beginner you should start with S132 v2.0.x and SDK 11.0.0.

Thank You! how did you know i am revision 1? does the B0 indicates it? (QFAAB0 ) what is a revision practical meaning?

[Petter Myhre]

The IC marking is explained here. B0 indicates it yes. Revision corresponds to version of hardware. You have engineering revisions, which can be used to test the chip, but shouldn't be used for production/in products. And you have production revision, which should be used for production/in products.

There are documents available which describe erratas with the different revisions, available here.
