Hi,everyone.

I had learn for below Links and compiling is no error. 

https://devzone.nordicsemi.com/f/nordic-q-a/26448/nrf52832-maximum-number-of-central-links/104063#104063

and  change 8 to 20 like:

// <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 - Total link count.
// <i> Maximum number of total concurrent connections using the default configuration.

#ifndef NRF_SDH_BLE_TOTAL_LINK_COUNT
#define NRF_SDH_BLE_TOTAL_LINK_COUNT 8

but I encount a problem  when the borad PCA10040 runing and the error show as below:

<info> app: Start s?<info> app: Multilink example started.
<info> app: Start scanning for?<info> app: Multilink example started.
<info> app: Start scanning for device name?<info> app: Multilink example started.
<info> app: Multilink example started.
<info> app: Start scanning for device name Nordic_Blinky.
<info> app: err is :0
<info> app: Multilink example started.

and also  I change the ram size  form the MDK  :

                Start                         Size

but no work and  the board always reset .

I don't know how to fit it and anyone who know please help me ,thanks!

Why do you have NRF_SDH_BLE_CENTRAL_LINK_COUNT = 20 but NRF_SDH_BLE_TOTAL_LINK_COUNT = 8 ? 

If you your device reset, could you check why it reset ? There is an useful link here on how to debug.
