[W-MBUS] “After different test, it seems that ‘s’ command works only in ‘RX only’ mode (test 3). Is it normal? “ Yes, you must force RX mode before using the ‘s’ command. Last Update: November 9, 2017 November 9, 2017 2122 Wireless M-Bus Q&A Related Knowledge Base Posts -[Wireless M-Bus] regarding the M-Bus packet frame, there are two fields named C-field and CI-field, for which I could not find explanation from Radio Crafts M-Bus user manual. Please send us the details of the documents explaining C and CI fields.[W-MBUS] “Regarding the modulation, I have a question about setting the modulation method. In my measurements , I changed the RF frequency with the volatile ‘C’ command. There is no volatile command to change the modulation method, so I left it at default. Then I find that the message transmission time at RF is the same for all channels, suggesting that the modulation scheme is the same. Is this the case, and is the default modulation valid for all channels? I need not be compatible with strict EN 13757. “[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?
