S120 Persistent storage initial clear command never executes

[Leon Schmetz]

I am using S120 v2 with SDK 6. Initialization of the softdevice and device manager return no errors. However when I want to start a scan for devices, the function checks the status of pstorage with pstorage_access_status_get and finds that the initial storage clear operation initiated by device_manager_central in dm_init when the option clear_persistent_data is set to true, has not been processed yet!

Looking into the workings of pstorage shows that a queued operation is executed only when a system event occurs (pstorage_sys_event_handler). This does not happen between start of the application and my scan request.

I cannot find any flaw in the initialization code of the softdevice, device manager and pstorage.

I hope someone has a clue as to what I am doing wrong or what I am missing. It might make a difference, I am using the scheduler.

PS Because the scan actually does not run (as it waits for pstorage to finish), the scan_stop function that runs on timer expiration, results in an application error caught by app_error_handler. The error says WRONG STATE, which of course is correct while scanning is not running at the moment of the stop request. Should I keep track of state or is there some function to check state?

I can understand that you have not tested it on older hardware. However I would like to gain some insight about what can be done because as it happens we have that hardware. We are inquiring with RF Digital if they have more recent hardware in the models sold at the moment. Until then I must do with what I have. I have a working application on the same hardware with softdevice 1.01. That would be the end of it if not for the fact that this version breaks the connection after 1 minute. So if you can help get that resolved, I am happy too. Still there must be something you can tell me why the same code (except for the necessary changes) would make it possible to scan for devices on s120 v1 and not on v2. It looks like I am not getting any events from the softdevice. I suspect something with the vector table but I cannot find what I should add or change to get it working.
