To establish a meter connection, the "client side' sends a SNRM + AARQ request. I would like to know if the 'client side' must send an RLRQ + DISC, or the only DISC to terminate this connection. What is the best practice in this issue?

Hi,

This depends from the meter. Best practice is to call RLRQ + DISC. There are some older meters that can't handle RLRQ. For this reason, GXDLMSDirector doesn't call RLRQ if a serial port connection is used.
