Hello,
I am interested in DLMS over Lorawan, but as DLMS have larger payloads and require more uplinks, dutycycles etc. So I want to know the DLMS over protocol data transmission structure.
Please guide me regarding DLMS over Lorawan protocol.
ThankYou
Dear,
Please find more information in DLMS blue books/green books, but in a nutshell:
SCHC-RFC9011 needs to be used in between DLMS and LoRaWAN layer, this SCHC protocol is handling segmentation & reassembly as well as header compression to avoid transporting unnecessary bytes. The stack is then:
(Device application) (Servers)
DLMS Layer DLMS Head & System
IPv6/UDP IPv6/UDP
SCHC SCHC
LoRaWAN <--------------------------> LoRaWAN
