How to connect EC200U-CN to Axon over UART

Can you help me to connect EC200U over UART? i tried but AT command is not responding,

I enabled UART1 as per this docs
https://docs.vicharak.in/vicharak_sbcs/axon/peripherals/uart/

EC200U-CN pinout

and it is already working over type c but in my project, UART is more important

@padaliyajay20,
Could you attach documentation of EC200U-CN like datasheet, AT command guidance etc !?
First, I need to look into it. Also share your setup picture over here as well.

Unfortunately ECM mode does not supported over UART, so i dropped plan to use UART for now. Thank you for your willingness to help.

my end goal is still to use UART with PPP mode but it is taking too much time and holding progress of project so i am leaving it for some days in future.
