NRF52832 Maximum number of central links

[muyang]

HI, I found that the maximum number of connections 52832 can only be 15 connections, like this

// <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 15
#endif

When I set up more than 15 when the compiler will be wrong, I would like to know what method can set the maximum number of links to 20

I am using the example is ：

nRF5_SDK_14.1.0_1dda907\examples\ble_central\ble_app_multilink_central\pca10040\s132\arm5_no_packs

When I use multiple connections, only the first connection, with BLE_DB_DISCOVERY_ARRAY_DEF (m_db_disc, NRF_SDH_BLE_CENTRAL_LINK_COUNT) will lead to discovery service several times, I configured the connection number is 2, the result is found twice the service, how to solve it,

I don't use db_discovery module and I recommend you not using it for such easy job either. It's probably not ready for multi-server project (as Nordic support team suggested in another Q&A on this forum they work with single Server/Client paradigm - which is incorrect for mutliconnectable GATT devices from my point of view but that's not so important, simply assume you are on your own).
