Wireless M-Bus Q&A Related Knowledge Base Posts - [W-MBUS] Since the user manual aslo states (again at pag. 4) that “When blue data appears, it doesn’t guarantee that this data has been sent over RF, it has been sent into the serial port only, as this depends on the state of the RF module”, I suspect that the RF module can be in different “states”. Is it true? Wich are these states? How can we handle them? [W-MBUS] We want to test MBUS protocol. It´s not for metering. If weuse MBUS protocol , must we follow the protocol for wake up/ sleep? [W-MBUS] “I activate the reception of the entire frame (start, header, rssi, crc & stop) using DATA_INTERFACE = 12. I wonder how to calculate this CRC? Is it a arithmetical sum of the following data : C field, Header, Ci field & payload as it is specified in M-bus documentation? “
