I am working on ESP-WROOM-02 Wifi Module and have flashed AT Firmware 0.50 with SDK 1.4.0 Version.
I have configured my Wifi Module as STA+AP Mode and conection link is below
My Laptop(STA)->ESP_Module(AP+STA)->External_Network_Router
so, ESP works as AP mode for my Laptop and works as STA mode for my Router.
I can ping to ESP Module successfully with 64bytes Data Request from my Laptop Device. I can also send ping request to "www.google.com" from my ESP Wifi Module using AT+PING Command.
But, I have observed that there are 1 to 2 ping requests are timed out when ping request is going on from my Laptop to ESP Wifi Module and from ESP Wifi Module to "www.google.com" at a time.
SO, It seems that there is high proority for STA mode interface in ESP Wifi Module when both STA and AP mode is configured and communication is going on in both interface.
Please let me know if anyone has idea or any information about this type of issue.
