[W-MBUS] For RC1180, we need to be sure it is WMBus compatible and have the standard and HP versions. I understand the legal restrictions and we will probably use the standard but need to ensure the hardware is compatible with higher version in case we need to use them?

RC1180-MBUS is not available as HP since the wireless MBUS specification not use the 500 mW sub-band. RC1700 is available in HP and low power and all information is given in the RC1700HP-MBUS data sheet.

[W-MBUS] “) I read OMS specification and now Data application Layer is much clear to me. Our goal is to use DLMS/cosem application layer over mbus. I saw in OMS specification that there is a correlation between VIF/DIF and OBIS code …but information about that are very weak. Have you got frames’ examples of DLMS Application in order to understand data exchange? “
[W-MBUS] In your RC1180-MBUS datasheet, we can see that the frequency tuning can change between 2 channels in mode S and T (868.3 and 868.95MHz). We chose the 868.95MHz for our transceiver and I would like to know for our test after the production what is the frequency tolerance and if there is a frequency calibration.
[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. “
