Thanks Sigurd. We'll do stuff from the main context. We're using BDS because the code needs to be completed quickly. No time to learn to do it from scratch.

Hi,

All the on_ble_evt() functions runs in interrupt priority APP_IRQ_PRIORITY_LOW. So you can call sd_() functions from this priority level. But you should not call things in a way so that it's prevents it from doing its other tasks, but short calls to other sd_ functions is fine.

If you are in fact doing very intensive processing you should do this from main context. In order to transfer execution from the interrupt context to the main context you can then use the scheduler. We have an old tutorial here and this post that might be useful.

Also note that the aim of BDS is fast prototyping. BDS plugin was updated for SDK 14, but it's machine generated code. You might want to learn how to write your custom services. See this Custom Service Tutorial on GitHub that is using the ble_app_template for more on that.
