sd_flash_page_erase() returns BUSY

[Konstantin K]

We have code that must erase a page in flash every once in a while, while S110 is advertising. The advertising interval is set to 0xF4 (which is about 150ms) and we have scan response data.

We are seeing that sd_flash_page_erase() returns error code 0x17 (busy) whenever we try to erase during advertising.

Can anyone suggest what's is going on or a way around this, short of stopping and restarting advertising?

Is the radio busy between advertisements (e.g. waiting for scan request or connection)?

Thanks,

Konstantin

Could you please give some information on which version of S110 and possibly SDK you are using? Are you making sure to wait for the NRF_EVT_FLASH_OPERATION_SUCCESS event or NRF_EVT_FLASH_OPERATION_ERROR event before doing another sd_flash_* command?

I was not checking for flash events. That is what caused the issue. After I made my page erase pend on the flash completion events, everything worked. For completeness, I was using s110 7.0 and SDK 6.0.

Thanks!
