cc2640r2f的simple_observer无限扫描的模式下，扫描过大概一个小时后，就扫描不到设备了？

是不是扫描设备的个数满了，看一下下面的参数设置:

#define GAPCENTRALROLE_MAX_SCAN_RES 0x404

Maximmum number of scan reports to store from GAPCentralRole_StartDiscovery (Read/Write)

size: uint8_t

default: 8

range: 0-256 but this will be constrained by available RAM

把 GAPCENTRALROLE_MAX_SCAN_RES 定义为0x404是什么意思

#define GAPCENTRALROLE_MAX_SCAN_RES 0x404

Maximmum number of scan reports to store from GAPCentralRole_StartDiscovery (Read/Write)

size: uint8_t

default: 8

range: 0-256 but this will be constrained by available RAM
