hi. I use sdk16 and ble sample like kb or mouse. i want to save some data in ic. with flash_fstorage.
i see flash_fstorage example .it can use SOFTDEVICE_PRESENT for save.
but i use in ble sample, it can not save .it happen "app_error_fault_handler".
if i do not use SOFTDEVICE_PRESENT, flash_fstorage can save data .but if use SOFTDEVICE_PRESENT in ble sample, it can not.
why? please.
i use nRF5_SDK_16.0.0_98a08e2\examples\peripheral\flash_fstorage\pca10056\s140\arm5_no_packs is OK.
but use nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_hids_mouse\pca10056\s140\arm5_no_packs
and the same code like flash_fstorage intialize , but it happen "app_error_fault_handler".
only sdk_config.h maybe different.
where is different , i do not konw..
nRF5_SDK_16.0.0_98a08e2_20200706.rar
hi ，this is my projcet, include flash_fstorage and ble_app_hids_mouse.
but only flash_fstorage with SOFTDEVICE_PRESENT is ok, ble_app_hids_mouse is fail
in ble_app_hids_mouse code,this is my modify like flash_fstorage.
The main reason that it is fails is that the ble_app_hids_mouse example uses the application scheduler to handle events from the softdevice. Since you try to write to flash right after initializing the softdevice but before initializing the scheduler, the scheduler queue will be filled before the events are processed, causing a NO_MEM error. I moved scheduler_init before fstorage calls.
Secondly, because the softdevice events are processed in main loop, the fstorage library will not receive the events from softdevice due to the blocking wait_for_flash_ready() call, preventing the application from reaching main loop. I added a call to app_sched_execute inside wait_for_flash_ready.
After fixing these two issues, the application got a hardfault because the fstorage_erase call erased one of the application code flash pages, but this may have been because I built the application with the debug configuration.
oh.. would you upload the modify code? i can try . please .Thanks.
