Abstract:
We will present our prototype implementation of the CoMatrix project, which enables the usage of the Matrix protocol for constrained IoT devices via CoAP and CBOR in a constrained network (e.g. a 802.15.4/6LoWPAN network). A CoMatrix gateway, which acts as a CoAP-HTTP forward proxy, was implemented based on the Python library aiocoap, and is running on a Raspberry Pi, which was extended with a 802.15.4 radio module. On the client side we use RIOT-OS on a SAMR21-xpro board and implemented an external CoMatrix library module based on gcoap and nanocoap. We like to share our experiences during the implementation and discuss some problems we faced, e.g.: Everything but Random – randomization of gcoap token on reset; Still not able to talk in secret – DTLS, OSCORE or openthread? Furthermore, we will give a short demo of two IoT use case applications: First the “CoMatrix chat” to show our current state of the client library functions. The latter is a temperature sensor application, which continuously sends temperature values into a Matrix room.
