Using Flash Data Storage to write Flash, turning BLE on results in FDS_ERR_BUSY in the flash write handler

[robin]

Using SDK nrf52_sdk_16.0.0
PCA10040 S132

My code can read and write Flash using the "Data Storage Flash" interface, IE calling  fds_record_write(...)  and waiting for events in my callback with no issue.

WHen I added BLE advertising using the example  nrf52_sdk_16.0.0\examples\ble_peripheral\ble_app_beacon   with no modifications i cant write to flash I get an FDS_ERR_BUSY in my callback.

I tried turning off ble adverting by calling sd_ble_gap_adv_stop(...)  but this doesnt seem to fix it.

What am I missing here ?

Do you enable the SoftDevice after initializing the FDS? If so, could you try to switch it, and see if the problem is still present? First enable the SoftDevice then initialize the FDS library, as suggested here.

If that doesn't work, could you upload your project and I'll take a look at it?

Best regards,

Simon

Hi Simon

Enabling the Softdevice before initializing the FDS solved the problem.

Thanks Robin
