Hi,
I have a Mg323-b,but I don't succeed in communicating with it in UART.
I'm using a FT230X in order to communicate via UART (though it does not support for DTR/DSR). I've allready used this FT230X to talk to a wide range of UART devices without ever a problem like this one.
When I power the Mg323 module I get on UART1 "IIII 0XFF 0XFF 0XFF 0XFF ^SYSSTART" and "^SHUTDOWN" When I power it down.But other than that it does not respond to any command like "AT".
On UART0 I don't get anything, and it does not respond to anything either.
I've tried almost all possible UART configuration .
It seems that some people do succeed in talking to the module:

Any Clue? (A particular handshake/init sequence needed? particular UART Config? Anything particular which could prevent UART1 or UART0 to work? Anything that is required for it to work, but that is not so striaghtforward?)
Thank's in advence.
Pierre.
