- [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] it seems that collisions between slaves create sometimes bit errors and the correction in your Errata Note 4 seems to solve it. However we are surprised that because of bit errors are present in a radio frame, this frame is not rejected (wrong checksum for example) and it is still analyzed (and in this case to find a non-supported encryption mode). Why ? Is there a risk to receive a frame from the RC1180 radio module with wrong data due to collisions ? “
