ESP32 WiFi : esp_wifi_scan_start fail

Postby Ankit53 » Fri Dec 14, 2018 6:42 am

Hi All,

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 case, without failing?

Thank You,
Ankit Siddhapura

I am using esp-idf v3.1 as well in older version 3.0rc1 seen same issue.

To choose best parent according to AP RSSI value, need AP info of all surrounded AP.

Code: Select all

wifi_scan_config_t scanConf;
esp_wifi_scan_start(&scanConf, true); 
Waiting for the event SYSTEM_EVENT_SCAN_DONE to get result of scan process. This case is generated when other application task is running. Interval of scan is 1 minuet.

Hi Espressif System SDK team,

I am working with Ankit regarding this support. So, Would you please check issue reported by him as i didn't get much time to see issue into depth for that.

So, Please let him know if you have any further query or need anything else regarding same.
