b. 首先调用esp_wifi_scan_start()搜索ap list,如果得到ap list包含有需要连接路由器的ssid,则调用esp_wifi_connect()进行连接,前面几次,打开路由器可以正常连接,若路由器关闭时间稍微长一些,则esp_wifi_scan_start()返回错误码0x300C,这个在esp_wifi_types.h没有定义,请问这是什么原因。 此外还尝试过在esp_w...

I came across the scenario like, setting up 20+ client in AP+STA mode, if Active scan is done by one node, in result not getting info of all APs. Using esp_wifi_scan_start API. API fail to get info of all 20+ clients in once scan event. How to achieve successful case in this...
I have since put in some code and found that esp_wifi_scan_start is returning -1. Is there code available for esp_wifi_scan_start (I can't find it) so that I can see why it would return -1, or does anyone know what causes -1? Thanks, Andy....

连接成功后,WIFI断开后自动重连。 可以设置是否连接失败后或者断开后,一直执行重连的任务。 设置最多5个SSID和PASSWORD,并从第一个开始尝试连接,失败后更换另一个尝试,直到成功。 增加获取板子的MAC地址,在某些场景下,可能需要通过MAC地址区分设备。 第三版修复了粉丝用C3板子,在连接上WIFI后无限重启的问题,S3、C6...
