检查USB端口模式
参考文档:
| GTUSBMODE | VID | PID | 操作系统 | 端口功能 |
|---|---|---|---|---|
| 31 | 0x1782 | 0x4d10 | Windows | |
| 32 | 0x1782 | 0x4d11 | Linux(Android) | ECM网口+MODEL+NV+MOS+DIAG+LOG+AT+AT |
| 33 | 0x1782 | 0x4d11 | Windows |
ttyUSB0、ttyUSB5、ttyUSB6可以用来响应AT，默认使用ttyUSB0
root@linaro-alip:/# echo "AT+GTUSBMODE?" > /dev/ttyUSB0
root@linaro-alip:/# cat /dev/ttyUSB0
AT+GTUSBMODE?
+GTUSBMODE: 32
OK
查询IMSI
root@linaro-alip:/# echo "AT+CIMI?" > /dev/ttyUSB0
AT+CIMI?
+CIMI: 460091*********
OK
查看IMEI,每个模块唯一
root@linaro-alip:/# echo "AT+CGSN?" > /dev/ttyUSB0
AT+CGSN?
+CGSN: "868680*********"
OK
查询批次号 S/N
root@linaro-alip:/# echo "AT+CFSN?" > /dev/ttyUSB0
AT+CFSN?
+CFSN: "KN69******"
OK
回复+CFUN:1 确认模块正常工作模式。 不是1则设置成1
root@linaro-alip:/# echo "AT+CFUN?" > /dev/ttyUSB0
AT+CFUN?
+CFUN: 1
OK
查询模块当前的固件版本号
root@linaro-alip:/# echo "AT+CGMR?" > /dev/ttyUSB0
AT+CGMR?
+CGMR: "16000.1000.00.06.71.15"
OK
确认SIM卡
root@linaro-alip:/# echo "AT+CPIN?" > /dev/ttyUSB0
AT+CPIN?
+CPIN: READY
OK
- 回复+CPIN: READY说明识别到SIM卡。
- 假如最少连接查询90秒仍然找不到SIM卡，复位模块。
- 如果需要PIN码则先用AT+CPIN设置PIN码。
APN (获取到IP)
root@linaro-alip:/# echo "AT+CGDCONT?" > /dev/ttyUSB0
AT+CGDCONT?
+CGDCONT: 0,"IP","wonet","10.215.50.83",0,0
OK
root@linaro-alip:/# echo "AT+COPS?" > /dev/ttyUSB0
AT+COPS?
+COPS: 0,0,"CHN-UNICOM",7 <--- 中国联通
OK
APN是模块即将选用的运营商网络的标识，建议联系SIM供应商确认设置对应的APN。
确认信号指标正常
root@linaro-alip:/# echo "AT+CSQ?" > /dev/ttyUSB0
AT+CSQ?
+CSQ: 31,99
OK
- 返回值格式为 +CSQ: <rssi>,<ber> 第一个参数<rssi>大于0并且不是99。
- 假如连续查询90秒返回值不正确，则复位模块。
- <ber>为误码率，0…7: 参考GSM 05.08中的RXQUAL值，99: 未知或不可检测。
| rssi | 信号 | 说明 |
|---|---|---|
| 0 | -113 dBm or less | |
| 1 | -111 dBm | |
| 20-30 | -109 … -43 dBm | |
| 31 | -51 dBm or greater | 信号优 |
| 99 | not known or not detectable | 无信号 |
PS域 (数据网络)
root@linaro-alip:/# echo "AT+CGREG?" > /dev/ttyUSB0
AT+CGREG?
+CGREG: 0,1
OK
- 查询结果是1或者5表示注册上PS域
- 连接查询超过90秒仍然注册不上PS域，复位模块。
激活
root@linaro-alip:/# echo "AT+GTRNDIS?" > /dev/ttyUSB0
AT+GTRNDIS?
+GTRNDIS: 0
OK
root@linaro-alip:/# echo "AT+GTRNDIS=1,1" > /dev/ttyUSB0
AT+GTRNDIS=1,1
OK
root@linaro-alip:/# echo "AT+GTRNDIS?" > /dev/ttyUSB0
AT+GTRNDIS?
+GTRNDIS: 1,1,"10.215.50.83","123.123.123.123","123.123.123.124"
OK
