CC3000能否读取信号强度，如何读取？

是通过这个API来做的wlan_ioctl_get_scan_results，你看它返回的结果里面有一项是rssi。

加一个下面的结构体：

typedef struct {
unsigned long networksFound;
unsigned long scanStatus;
unsigned long isValid : 1;
signed long rssi : 7;
unsigned long securityMode : 2;
unsigned long ulSsidLen : 6;
unsigned long frameTime : 16;
char ssid[32];
unsigned char ucBssid[6];

} wifi_scan_result_t;

然后代码片段如下：

static unsigned char buffer[50];

wifi_scan_result_t *result = (wifi_scan_result_t *) buffer;

memset(buffer, 0, sizeof(buffer));

if (wlan_ioctl_get_scan_results(0, buffer) != 0)
{
return -2;
}
