PM_EVT_ERROR_UNEXPECTED using the new SDK v12

[ivan]

We are trying out the new nRF5x SDK v12 and it looks like the previously working ble_app_hids_mouse example is broken now.

It compiles successfully, but as soon as we try to pair a new device with it, pm_evt_handler() is called with PM_EVT_ERROR_UNEXPECTED and the pairing fails.

I can confirm that the same example from the SDK v11 works properly with the same hardware. We are using the PCA10028 board (nRF51-DK).

Is there any known workaround for this?

OK, received a newer revision of PCA10028 (v1.2.0; 2016.11) and it works. Looks like the new SDK is no longer compatible with the older revisions of PCA10028 (we had v1.0.0; 2015.25).

Good that it works. v1.0.0, v1.1.0, v1.2.0 should have the same chip on them, so I find it a bit strange that you get this error. I don't have v1.0.0 to test with here, but it seems to work fine on v1.1.0. What are the complete laser markings of the nRF51422 on the v1.0.0?

That is N51422QFACA11503AD. Do you have some sort of a "silicon revision" register that I could check with a debugger and help you identify the chip?

It is revision 3, the same revision as mine on v1.1.0. You can use this matrix to figure out what revision it is.
