4.5. 蓝牙低功耗
概述
使用demo_edr工程配置蓝牙低功耗。
4.5.1. 操作说明
在app_config.h文件中修改以下宏:
#define CONFIG_LOW_POWER_ENABLE //软关机/睡眠开关
#define TCFG_LOWPOWER_LOWPOWER_SEL (RF_SLEEP_EN | SYS_SLEEP_EN | RF_FORCE_SYS_SLEEP_EN | SYS_SLEEP_BY_IDLE)
设置蓝牙功率接口( 详情查询[btcontroller_modules.h](include_libbtctrlerbtcontroller_modules.h) )
