If you need to also erase pages while in a connection, you need to make sure the connection interval is sufficiently long for this to be possible, i.e. > 21 ms (most likely > (21 ms + some processing time)), and do the erase right after the radio event. The ble_radio_notification module from the SDK can be used to get a software interrupt both some time before and right after an event.

If you have further questions on this, or can't get it working, it might make sense to post it as a separate question.

Good! I didn't realize that you were also doing BLE communication when this failed.

I have found it! It's BLE radio active while FLASH Erase! Because Erase Page in FLASH memroy need time(21ms type), radio notificatio can't guarantee safely operate. example: if first Erase FLASH Page while radio not active, then during 21ms radio avtive.

Did you see my answer to your other question regarding this error?

If that did not help, could it be that you actually erase the page you're running from? How do you call this method? You do a cast of a uint32_t pointer to a uint32_t, which could easily give problems if you're not careful with the parameter.
