[W-MBUS] What is the difference between MBUS3, MBUS4 and MPC1?

The MBUS3 and MBUS4 protocols act as Wireless M-Bus modems with a UART command and data interface. The MPC1 provides a pulse counter application on top of the Wireless M-Bus protocol and can therefore be used as a complete and autonomous solution for any meter that provides a pulse output.

[W-MBUS] “When I activate UART_FLOW_CTRL = 3 (CTS/RTS), I didn’t succeed to receive & send datas with the RC1180 when I activate RTS/CTS on application side. “
[W-MBUS] About the sniffer: when I configure the Sniffer as a slave, should I see all master messages to all slaves (independent of the address configuration)?
[W-MBUS] “I configured the MBUS radio to use the UART flow control using the CTS/RTS pins. When the host processor wants to send an MBUS message, it pulls the RTS pin low and waits for the radio to pull CTS up. The processor then sends the message. But this gives strange results, and sometimes it just fails to send the message. I also tried using only the CTS pin, where I wait for the pin to go high before sending the message. Again, this does not always work. Are the CTS/RTS pins exclusively for controlling the flow over the uart connection (host processor to radio) or are they meant to indicate when the radio can send another message ? If so, how should I use them ? “
