Hi,
I have a set of LoRa nodes with a SX1301 Gateway and I have costumers requiring wireless M-Bus communication. I can see that SX1301 support this, but I can’t find any info on how to implement it. I just need to send some data to a wM-bus gateway on the 868MHz band and right now I am using the https://github.com/Lora-net/lora_gateway software.
Would it work by using the FSK modulaiton?
Thanks in advance!
Best regards,
Thibault
In the 1st instance if looking at WMBus over LoRa/LoRaWAN I would suggest you contact my old friends at Amiho Technology in Cambridge UK (believe they have recently been bought out by inVMA) - speak to Steve Clarke if you can. I know they have done a lot or work and product dev in this area over the last 3-5 years with software and radio modules/modems for LoRa available. I would also suggest you reach out to the guys at iMST who I recall have good experience with WMBus and of course are experts in the LoRa area, not sure if they have done work on WMBus over LoRa/LoRaWAN or WMBus/LoRa bridging but if you contact Heinz or the guys on the LoRa/Wireless team am sure they will point you in the right direction…
Of course folk on the forum may have other suggestions - people like Jose @jmarcelino Jak @kersing and Rob @BoRRoZ are often fonts of such knowledge or know contacts 
Stackforce is the developer of the main WMBus stack and maintainer of the LoRaMac-node stack https://www.stackforce.de/en/products/wireless-m-bus-stack

Yes the SX1301 can receive wmbus data. You have to edit the libloragw libraries though (change the parameters for the FSK demodulator to receive WMBUS, and change the parameters for FSK transmission [remove whitening for example, no data encoding, no crc…] ).
