Regarding the dlms android project

Gurux DLMS for Android

In GXDLMSDirector, I was able to successfully read data without explicitly setting the baud rate. However, in the Android application, selecting a baud rate is mandatory — there's no option to leave it unset. Even after selecting the same baud rate as used in GXDLMSDirector, the Android app fails to retrieve any data.

Hi,

The baudrate is always mandatory.
Are you using HDLC or HdlcWithModeE in GXDLMSDirector. GXDLMSDirector uses the 9600 as a default value with HDLC.

Hi,

Select "Media Settings" and then select "Info". Who is the manufacturer, and what are the vendor and Product ID?

Hi,

Please, don't add example code. It doesn't help.

The meter doesn't send a reply for some reason. Can you select "Show trace" in Android. What is the hex string that the client sends?

BR,
