- [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] “The WM-Bus module on my PoC unit sometimes stops sending serial messages (eg overnight). The Radiocrafts Demo PCB continues to receive OK, so it’s not the radio signal stopping, it’s the module serial output stopping. It starts again after turning Vdd off and on. This could be radio interference on the PCB wires perhaps, eg insufficient filtering on the serial data wires or Vdd wire, so I will improve that on the PCBA. “
