之前的问题是串口驱动问题，已经解决。不过还有几个新的问题。1
1、解析AT+CIPSTA？失败，导致后面的ip、gateway、mask设置失败。
```
msh />01-01 08:00:01 I/at.dev.esp32 at_clnt0: esp32 device wifi is connected.
01-01 08:00:01 I/at.dev.esp32 at_clnt0: esp32 device wifi is disconnect.
01-01 08:00:02 I/at.dev.esp32 at_clnt0: esp32 device wifi is connected.
01-01 08:00:02 I/at.dev.esp32 at_clnt0: esp32 device wifi is disconnect.
01-01 08:00:03 I/at.dev.esp32 at_clnt0: esp32 device wifi is connected.
01-01 08:00:03 I/at.dev.esp32 esp_net: esp32 device network initialize successfully.
01-01 08:00:04 E/at.dev.esp32 sys_work: esp32 device prase "AT+CIPSTA?" cmd error.
01-01 08:00:04 E/at.dev.esp32 sys_work: esp32 device prase "AT+CIPSTA?" cmd error.
01-01 08:00:04 E/at.dev.esp32 sys_work: esp32 device prase "AT+CIPSTA?" cmd error.
```

2、用ifconfig手动设置ip、gateway、mask失败。
```
msh />ifconfig esp32 192.168.0.125 192.168.0.1 255.255.255.0
config : esp32
IP addr: 192.168.0.125
Gateway: 192.168.0.1
netmask: 255.255.255.0
01-01 08:02:10 E/at.clnt tshell: execute command (AT+CIPSTA="192.168.0.125","0.0.0.0","0.0.0.0") failed!
01-01 08:02:10 E/at.dev.esp32 tshell: esp32 device set address failed.
01-01 08:02:10 E/at.clnt tshell: execute command (AT+CIPSTA="0.0.0.0","192.168.0.1","0.0.0.0") failed!
01-01 08:02:10 E/at.dev.esp32 tshell: esp32 device set address failed.
01-01 08:02:10 E/at.clnt tshell: execute command (AT+CIPSTA="0.0.0.0","0.0.0.0","255.255.255.0") failed!
01-01 08:02:10 E/at.dev.esp32 tshell: esp32 device set address failed.
```

试了一下esp32的at+cipsta指令不能像上面一样单独设置ip、gateway、mask，只能把合法的ip、gateway、mask写到一条指令里面，或者只设置ip。
```
at+cipsta="192.168.0.125","192.168.0.1","255.255.255.0"
WIFI GOT IP

at+cipsta="192.168.0.125"
WIFI GOT IP

at+cipsta="192.168.0.125","0.0.0.0","0.0.0.0"
ERROR

at+cipsta="0.0.0.0","192.168.0.1","0.0.0.0"
ERROR

at+cipsta="0.0.0.0","0.0.0.0","255.255.255.0"
ERROR
```

上面这两个是不是真的有问题？
