GAP_DeviceInit(GAP_PROFILE_PERIPHERAL, selfEntity, addrMode, NULL); 把NULL修改为mac_addr后无法扫描到设备，这样设置不对吗？

如题：simplelink_cc13x2_26x2_sdk_3_40_00_02中例程，代码修改为如下，无法扫描到设备，

void GetMacAddress(uint8_t *p_Address)
{
uint32_t Mac0 = HWREG(FCFG1_BASE + FCFG1_O_MAC_BLE_0);
uint32_t Mac1 = HWREG(FCFG1_BASE + FCFG1_O_MAC_BLE_1);

p_Address[5] = Mac0;
p_Address[4] = Mac0 >> 8;
p_Address[3] = Mac0 >> 16;
p_Address[2] = Mac0 >> 24;
p_Address[1] = Mac1;
p_Address[0] = Mac1 >> 8;

}

uint8_t mac_addr[6];
GetMacAddress(mac_addr);

//Initialize GAP layer for Peripheral role and register to receive GAP events
GAP_DeviceInit(GAP_PROFILE_PERIPHERAL, selfEntity, addrMode, mac_addr);
