Creation

ANNEX 1: LwM2M PROTOCOL

The COMFORT product can be configured to use one of the following two protocols to exchange data 
with an IoT platform: MQTT or LwM2M.

❗

Adeunis recommends the use of the LwM2M protocol as it is the ONLY protocol that
minimizes the consumption of the COMFORT product and ensures remote
operational management.
