AT command receiving large data

[potec_hw02]

Hello,

I am developing using ESP32_WROOM-32D with AT command version 2.1

when using only two wifi module, data sending/receiving of UDP packet is fine.
the sending part of ESP32 indicated the "busy" message to debug console.

but when I receiving with another device (PC or etc), ESP32 lost large part of data.
the sending part(PC or etc) sends UDP data of 512bytes instantly.
the receiving part(ESP32) lost data partly.
it seems that the first few bytes are correct but hundreds of byte missing, then correct a few bytes.

I am using ESP32 as AP+SoftStation Mode.
so, I want to know the bandwidth of ESP32 module when using AT command.

also How can I resolve this problem?

Best regards,
Kim
