Advertising problems after change of chip revison (QFAAB0 -> QFAAE0)

[OlaHallstrom]

We have tested the same code on two boards with different revision of chips

nRF52832 QFAAB0  : advertising ok

nRF52832 QFAAE0 : advertising does not work

We are using SDK version 15.0.0 and softdevice S132. The hw schematic is identical when it comes to radio parts but differs in other aspects.

Are there any known compatibility issues between chip/SDK version? Tried to read erratas but its a bit confusing since chip revision is documented as numbers (1, 2, ...) when using letters on the chip package.

Ok thanks. No I don't get any error codes returned (unless forgetting to pick them up). Advertisment start returns ok and looks exactly as when running on the older revision. I will involve our hw enginneeer in the loop as well. We will get back...

Hi Ola,

Sounds good.

Hi Einar,

Just opened a new private case with gerbers and some more info. Is it possible to have a brief skype or similar session?

Hi Plamen,

A colleague of mine is reviewing your HW files now and will get back to you in the private case.

Thnks, Einar!

Hi,

We got a new batch of boards. The first one is working as expected. I still do not know why the previous does not. They are identical...

I would suggest that we close the case.

Cheers / Plamen

Hi Plamen,

Thanks for letting us know.
