EG800KEULCR07A04M04 issue on HTTPREAD data transfer with MAIN_UART

IoT Modules LTE-A Module
1

Model: EG800K
Version: EG800KEULCR07A04M04

Modem is connected by MAIN_UART at 115200,None8,1 with RTS/CTS Handshaking
I try to download data with HTTPREAD command.
The answer seem incomplete, transfer size is about 500kB but at the end I never receiver “OK” but only “HTTPREAD: 0”.
It seems that data transfer doesn’t respecet bus speed and there is a cosiderable data loss, as confirm of this I can report the time of download is only a couple of seconds and this time is not comparable with UART baudrate configured.

Anyone else has worked this same modem and firmware version?

Expect that you can provide your complete AT log

I provided AT log just to prove my try, but some data are hided for privacy.
This issue is already reported to Quectel field eng. from my company, but it takes longer to receive usefull answer, I’m trying to share tought in community to catch similar behaviours.
I also already shared a QWinLog of type QASR to Quectel field eng.

Thanks for your time
