Need help for scan_evt timeout error

[Ritesh]

Hello Team,

We are using Wi-Fi and BLE together into one of our IoT based application in which below is overall scenarios for application perspective.

1. Board Start with ESP32 Device work as STA Mode
2. Enable BLE and scan parameter using esp_ble_gap_set_scan_params
3. Also tried to scan list of Access Points and connects with particular SSID
4. Connect with HTTP Client and send some data
5. Repeat above cycles every 15 Minutes of duration

But we have seen that sometimes we are seeing below prints continuously into random way. I am not sure that from where it is coming and what is the impact of it.
