nordic nRF52832 多主一从的最大的连接数配置
支持一主多从的协议栈：s132_nrf52_6.0.0_softdevice.hex；SDk：nRF5_SDK_15.0.0_a53641a
1、打开sdk_config.h配置为最大的连接数20
//
#ifndef NRF_SDH_BLE_PERIPHERAL_LINK_COUNT
#define NRF_SDH_BLE_PERIPHERAL_LINK_COUNT 20//4
#endif
//
#ifndef NRF_SDH_BLE_CENTRAL_LINK_COUNT
#define NRF_SDH_BLE_CENTRAL_LINK_COUNT 0
#endif
//
// 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//4
#endif
编译出错：
2、提示没定义：找到这个文件app_util.h，添加红色的部分。

编译还是有错误：
3、根据提示：还是这个文件app_util.h，添加红色的部分。
#define MACRO_MAP_FOR(...) MACRO_MAP_FOR_(__VA_ARGS__)
#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
#define MACRO_MAP_FOR_(...) MACRO_MAP_FOR_N(NUM_VA_ARGS_LESS_1(__VA_ARGS__), __VA_ARGS__)
编译通过：
在修改一下内存空间：
烧录测试，只验了三台手机。结果如下：
