SD140 6.0.0-6-alpha BLE issues

[Julie H]

Greetings -

I recently downloaded the latest SD140 images, 6.0.0-6-alpha, and began having issues with BLE communication.

I'm developing a custom device, based on the nRF52840, and we require both BLE and USB communication. The USB peripheral seems to be pretty much broken when the Soft Device is enabled, so I'm going to ignore that for the moment.

I recently migrated our code from the previous Soft Device, 5.0.0-5-alpha, which had working BLE (NUS and other services). When I attempted to discover and connect to the device using nRF Toolbox, I was unsuccessful. I reverted my code to the last working, pre-USB version, to remove any possible USB issues. This didn't resolve the problem. The only way to get BLE working again was to switch back to the 5.0.0-5-alpha version of the Soft Device.

Nice. Not sure how your experience in operating systems relates to understanding of Nordic Soft Device API but it doesn't matter;) And you are right (and I'm sorry), there seems to be no migration guide attached to S140 V6 alpha pack yet. Probably still too early alpha release. So then the only truth is in raw diff and when I compare V5.0.0-alpha.3 and V6.0.0-alpha.6 there are clearly small changes in basically all the layers and modules so you might need to go change per change and see if you use these SD API calls and structures or not.
