Gurux.DLMS

Hi,

I am trying to communicate with SL7000 meter using GuruxDLMS.c library.

I've made a cross compilation for i.MX6 processor for the library and the GuruxDLMSClientExample.

The Processor card is connecting to the meter using RS232, when I tried to connect I got an error message : Invalid frame 10. Expected 30.

I attached to log for the communication.

Can you help me to solved this problem ?

Thank you for the information and your feedback,

Best regards,
Dávid

Hi,

You are only receiving the echo from the RS-232 converter. If you remove the device you get the same reply. The meter doesn't reply for some reason.

Your server address might also be different than the meter expects. Try this:

-S /dev/ttymxc2 -t Verbose -i HDLC -s 145

Check your cables if you still don't can't connect to the meter.

BR,
Mikko
