using ota..

During OTA updates(wifi), can i use BLE?

Sometimes, the update pause during the update, or the update does not start at all.

BLE checks whether OTA update is completed.

Kindly give your feedback as soon as possible.

Thanks in Advance!

esp32 wifi connection status

hi there,

How do I check the connection status after entering wrong SSID and password when connecting to WiFi AP?

esp_wifi_connect () Should I check with the return value?

The return value of esp_wifi_connect () is always ESP_OK.

Can anyone help me?
