AMR PULSE W-Mbus- Mode d'emploi / User guide version V1.2

4. Radio frames

The AMR PULSE transmits raw information from meters using the wireless M-BUS protocol.
This section contains information you can use to decode the wireless M-Bus frame as well as the location in the frame of information concerning
the meter or meters associated with the AMR PULSE.
The decoding explained below, starts from the following example:
• An AMR PULSE product to which a water meter is connected. The frames transmitted are data frames and history frames.
