emqx_coap

The CoAP gateway implements publish, subscribe, and receive messages as standard with Publish-Subscribe Broker for the CoAP.

Quick Start

In EMQX 5.0, CoAP gateway can be configured and enabled through the Dashboard.

It can also be enabled via the HTTP API or emqx.conf, e.g. In emqx.conf:

gateway.coap {

  mountpoint = "coap/"

  connection_required = false

  listeners.udp.default {
    bind = "5683"
    max_connections = 1024000
    max_conn_rate = 1000
  }
}

Note: Configuring the gateway via emqx.conf requires changes on a per-node basis, but configuring it via Dashboard or the HTTP API will take effect across the cluster.
