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.

    Hi Ola,

    There are some errata that are fixed in revision 2 (QFAAE0), but none that should require any changes in your code, so I would not be surprised if your hardware changes are related to this. What are the most significant changes? Have you tried to debug to see what is happening on the device which is not advertising? What state is it in? I san error check hit, or is there a function not returning, or something else?
