emqx_mqttsn

The MQTT-SN gateway is based on the MQTT-SN v1.2.

Quick Start

In EMQX 5.0, MQTT-SN 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.mqttsn {

  mountpoint = "mqtt/sn"

  gateway_id = 1

  broadcast = true

  enable_qos3 = true

  listeners.udp.default {
    bind = 1884
    max_connections = 10240000 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.
