前两年买的开发板,想使用at功能,需要把波特率降下来,但是那个at版本好像没有这条指令。
于是我从下载了最新的sdk,刷bin/at/下的bin,刷好后,用串口观察,一直在输出数据一样的东西,at指令貌似还可用,查询版本,内容如下:
AT version:1.3.0.0(Jul 14 2016 18:54:01)
SDK version:2.0.0(656edbf)
compile time:Jul 19 2016 18:43:55
OK
没有指令时,一直输出类似下面的内容:

我准备使用arduion跟它通信,这么老是刷数据,影响我接收有用的数据。
第一次发帖,刚才那个没发出去吗?
刷完最新的AT固件之后,一直从串口打印数据,我刷错了吗?
