CPU Unblocking, BLE Radio Notification and pStorage Access

[sam wagner]

The following thread talks about CPU unblocking during connection intervals.

devzone.nordicsemi.com/.../

• How does this feature affect BLE Radio Notification? Do I expect any difference in the Radio Notification pattern?

• Currently, I am using BLE Radio Notification to find safe times for pstorage access during connection interval when BLE connection is up (SDK6.1). If I enable CPU unblocking (in SDK7.2) feature, do I still need to use BLE Radio Notification feature for safe pstorage access or I can just disable BLE Radio Notification and access pstorage directly?

Thanks, Sam

Hi Sam,

"unblocking" the CPU during connection intervals will not have any timing implications on the radio_notification. As Pstorage uses the sd_flash-API to store/erase flash, it is considered safe to use at any time (as it queues cmd's), but if you use it with combination with the radio_notification you're certain that you will have a longer period where you're not interrupted by the stack.

Cheers, Håkon

Thank you so much for the clarification. I will close the issue.
