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 guess Nordic's db_discover module isn't ready for multiple servers. In other words you have some logical flaw in your state machine and I recommend to do your own GAP and GATT logic not using these high-level SDK modules. They should make the things easier but from they are for simple use cases and beginners. They need to be as general as possible which kind of mean that for optimized production use case you probably want to do the logic yourself.
