i has solved this problem, it need to adjust the memory address, you can get this message by the log output.

oh, I find a new problem now.

change the max link count to 20

// <o> NRF_SDH_BLE_PERIPHERAL_LINK_COUNT - Maximum number of peripheral links. 
#ifndef NRF_SDH_BLE_PERIPHERAL_LINK_COUNT
#define NRF_SDH_BLE_PERIPHERAL_LINK_COUNT 0
#endif

// <o> NRF_SDH_BLE_CENTRAL_LINK_COUNT - Maximum number of central links. 
#ifndef NRF_SDH_BLE_CENTRAL_LINK_COUNT
#define NRF_SDH_BLE_CENTRAL_LINK_COUNT 20
#endif

// <o> NRF_SDH_BLE_TOTAL_LINK_COUNT - Maximum number of total concurrent connections using the default configuration. 
#ifndef NRF_SDH_BLE_TOTAL_LINK_COUNT
#define NRF_SDH_BLE_TOTAL_LINK_COUNT 20
#endif

The project has Compiled succssfully and passed,but i download it in the board , the project is not run.if change the max link count from 20 to 8, that is ok.

Are there any other places to be modified？

Hi,

I got the exact same result here when trying to reproduce.

It turns out, at least in SDK 14.2, you have to also change the line

#define MACRO_MAP_FOR_N_LIST 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

#define MACRO_MAP_FOR_N_LIST 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20

in order for the REPEAT_FOR macro to work.

Regards,
Terje
