Fstorage timeout error

I think I found the issue.

I had the supervisory timeout set very low in order to disconnect quickly when out of range.

MSEC_TO_UNITS(250, UNIT_10_MS)

by increasing this to 500ms it seems to work every time. I increased it to 1000ms for some head room.

I am guessing having that low of a timeout didn't allow enough time to erase the flash(?)

Setting higher connection interval would result in more time to erase the flash.

Could you test the attached main.c in ble_app_uart (SDK 14.2) and check if flash erase works at your side?

devzone.nordicsemi.com/.../main.c

Test the code:

Connect to a central
Test flash write and erase:
1. Press button 3 to erase.
2. Press button 4 to write.

Kristin,

Yes I have the following set:

// <i> NRF_FSTORAGE_SD uses the nrf_fstorage_sd backend implementation using the SoftDevice API. Use this if you have a SoftDevice present.
// <i> NRF_FSTORAGE_NVMC uses the nrf_fstorage_nvmc implementation. Use this setting if you don't use the SoftDevice.
// <1=> NRF_FSTORAGE_NVMC 
// <2=> NRF_FSTORAGE_SD

#ifndef FDS_BACKEND
#define FDS_BACKEND 2
#endif

However, I don't believe this setting should matter since I am using Fstorage rather than FDS correct? Since FDS_ENABLED is set to '0', the FDS settings should not matter for the Fstorage library right?

Which setting do you have for FDS_BACKEND?

When using the softdevice, make sure that FDS_BACKEND is set to NRF_FSTORAGE_SD in sdk_config.h so that fds.c includes nrf_fstorage_sd.h.
