[W-MBUS] How can I do two-way communication using Wireless M-Bus?
[W-MBUS] As far as the data format is concerned, the “”MBUS-CCT user manual”” states: “”To send ASCII characters, type them in and hit the enter key or click on the send once button””. In case bytes have to be sent, we know that te first byte should be the Length byte. We tried to transmit the same bytes sequence shown as an example in the user manual (pag. 4): ‘5 0x33 0x25 6 78 7’. In both cases (ASCII and bytes transmission) nothing is transmitted across the link (or at least nothing appears at the receiver side). Comments?
[W-MBUS] “I’m currently working on a wireless M-Bus project, and I try to run the developement kit with meters. In fact, I get to receive a frame sent by a counter, but I can not return it even if I put the module in “”Repeaters Mode”” “
