Quectel-uart-ddp integration

Hi,
I am trying to use quectel-uart-ddp function for my integration of UART with another module. While running in the adb shell, quectel-uart-ddp functions keeps quite for a while and come to shell. I have enabled main uart1 with AT commands also. Is there any conflicts are happening in my firmware version of EG-25G module.

hi,
What is the current version? Do you have specific screenshots?
