My company has migrated to CSR1024. We have no problem on getting to sleep deep at CSR1010 to 5uA. I believe other developers using 1024 encounter the same issue.
Our current consumption is at 13.6uA, by disabling advertisement with semaphores. Our application need to be at 5uA.
I called the SleepModeChange(sleep_mode_deep); but the current has not dropped. No changes to the current at all.
Also, there is a current burst on every 5 seconds. I have check every TimerCreate and tried to use any combination of scan interval and scan slot but nothing changes.
So far no support from Qualcomm. Any hints from fellow developers will be highly appreciated
