[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? "

You will find a list of OBIS Codes for Basic Meters and OBIS Declaration via MBUS in OMS spec Vol 2 Annex A and B. Additional information about DLMS is described in EN13757-1 Data exchange.

[W-MBUS] “We are interested in using Radiocrafts modules in our product. We need to install around 150+ sensors per house which are connected to one concentrator (master) device. Sensor are small and therefore using external antenna is not an option which may be problematic when using 169MHz? Those sensors are installed into houses with concrete walls and range requirements are therefore at least 150+ meters in NLOS situations. We are considering to use Wireless M-BUS protocol or some similar which do not require acknowledgements from the sensor. We prefer sub 1-GHz radio because of coverage. Could you suggest some of your modules which support 150+ slaves in one network and extended range at least 150+ meters in urban area? Please also take into account our antenna limitations. “
[W-MBUS] Say we have 1 central unit with 1 wMBus receiver and another wMBus device with bi-directional communication, can the central unit operate in T2 mode and communicate with both types of end devices?
[W-MBUS] What happens if there are two MBUS masters in the range of a slave?
