C语言 | 如何使用 sscanf 提取AT命令返回结果中的有效数据

#include <stdio.h>

int sscanf(const char *s, const char *format, ...);

+CSQ: 17,0

OK

str = strstr(buffer, "+CSQ");

if (!str) {
 return -1;
}

ret = sscanf(str, "+CSQ:%d,%d", &rssi, &ber);
if (ret != 2) {
 return -1;
}

+CREG: 2,0,"252A","6DD2104",7
OK

sscanf(buffer, "+CREG:%d,%d,\"%4s\",\"%7s\"", &n, &stat, lac_buf, ci_buf);

+CIFSR:STAIP,"10.89.100.53"
+CIFSR:STAMAC,"dc:29:19:bb:d7:d3"
OK

sscanf(str + strlen("STAIP,"), "\"%d.%d.%d.%d\"", &seg1, &seg2, &seg3, &seg4);

sscanf(str, "STAIP,\"%d.%d.%d.%d\"", &seg1, &seg2, &seg3, &seg4);

+CIFSR:STAIP,"10.89.100.53"
+CIFSR:STAMAC,"dc:29:19:bb:d7:d3"
OK

sscanf(str + strlen("STAMAC,"), "\"%2x:%2x:%2x:%2x:%2x:%2x\"", &seg1, &seg2, &seg3, &seg4,&seg5,&seg6);

+CWLAP:(4,"TP-LINK_PocketAP_DFBCD4",-57,"38:83:45:df:bc:d4",6)
+CWLAP:(3,"LSTM",-61,"8c:21:0a:bc:8e:70",13)
+CWLAP:(3,"LabWiFi",-62,"68:3b:78:8f:16:23",1)
+CWLAP:(0,"GuestWiFi",-64,"68:3b:78:8f:16:22",1)

OK 

strstr(buffer+offset, "+CWLAP:");

sscanf(str+strlen("+CWLAP:"), "(%d,\"%[^\"]\",%d,\"%[^\"]\",", &ecn, ssid, &rssi, mac);

while (*str++ != '\n') {
     offset++;
}
