problem with fds in the light swich project

[UdjinPr]

Hello, I am trying to combine light switch client example with fds functionality.

For these I did next steps:

1. Included all ‘c’ files from the fds example to the light switch project.
2. Added links for all ‘h’ files to the "User Include Directories" in light switch project 
3. Activated necessary variables in the sdk_config.c 
4. Copy main.c from the fds_flash to the light switch project. 
5. Changed all NRF_ messages to __LOG l.

As a result there aren’t any mistakes after compilation project, but program sticks in wait_for_fds_ready() function in the loop.

 

My main.c.: 

 

#include <stdint.h>
#include <string.h>
#include "nrf.h"
#include "nordic_common.h"
#ifdef SOFTDEVICE_PRESENT
#include "nrf_sdh.h"

Hi. 

I am trying to combine light switch client example with fds functionality.

From what I can see, you removed all the mesh/light switch functionality from the example?
Anyway, from the FDS Documentation: 
NOTE: Before initializing FDS, you must initialize the SoftDevice and register a callback handler to handle FDS events. 

From what I can see, you've commented out the softdevice initialization.

Best regards, 
Joakim

Hi,

    I have met the same situation, But I have Init Function: ble_stack_init(); The result is same with you . Have you sloved this issue ? if so,How ?

Best regards,
