Failed to send/receive M-Bus request

[wmmihaa]

Hi (long time no see) We have been using node-mbus for quite a while without any issues, but I just ran into one that I can't resolve...

Our gateway which is running the node-mbus package is connected to an mbus master (Elvaco) which in turn has four of meters connected to it. We can read two of them, but while reading the others we get this:

Can you please retry with 1.2.0? And then? maybe you can try to use some other mbus software? Is it working there? Whats the difference in send/received messages=

Sorry I missed that you had answered... But the issue was resolved after updating to 1.2.

My apologies!
