[W-MBUS] How many times can I write a KEY to the MPC1 The max write cycles is 1000, Last Update: September 14, 2017 September 14, 2017 2578 Wireless M-Bus Q&A Related Knowledge Base Posts -[W-MBUS] How can we define, where a data package (sending out of the module) starts and when does it stops.[W-MBUS] Is there any other “Trick” that you can explain to me like the existence of the “s” command[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. “
