[W-MBUS] Is there any way to check the reliability of communication ?

If you enable RSSI append you will get the signal strength of the received packets. This will inform if you have margins to the sensitivity limit. If you place the two boards to close together your receiver will reach saturation due to strong signals from the transmitter. This will give packet losses. Try to use at least one meter between the boards and repeat the test.
