# emqx_coap
|
||||
|
||||
The CoAP gateway implements publish, subscribe, and receive messages as standard
|
||||
with [Publish-Subscribe Broker for the CoAP](https://datatracker.ietf.org/doc/html/draft-ietf-core-coap-pubsub-09).
|
||||
|
||||
## Quick Start
|
||||
|
||||
In EMQX 5.0, CoAP gateways 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:
|
||||
|
||||
```properties
|
||||
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.

|
||||
EMQX Gateway
|
||||
EMQX Gateway is an application that managing all gateways in EMQX.
|
||||
|
||||
## Concept
|
||||
It provides a set of standards to define how to implement a certain type of
|
||||
protocol access on EMQX. For example:
|
||||
|
||||
EMQX Gateway Management
|
||||
- Gateway-Registry (or Gateway Type)
|
||||
- *Load
|
||||
- *UnLoad
|
||||
- *List
|
||||
- Frame parsing
|
||||
- Access authentication
|
||||
- Publish and subscribe
|
||||
- Configuration & Schema
|
||||
- HTTP/CLI management interfaces
|
||||
|
||||
- Gateway
|
||||
- *Create
|
||||
- *Delete
|
||||
- *Update
|
||||
- *Stop-And-Start
|
||||
- *Hot-Upgrade
|
||||
- *Satrt/Enable
|
||||
- *Stop/Disable
|
||||
- Listener
|
||||
There are some standard implementations available, such as [Stomp](../emqx_stomp/README.md),
|
||||
[MQTT-SN](../emqx_mqttsn/README.md), [CoAP](../emqx_coap/README.md),
|
||||
and [LwM2M](../emqx_lwm2m/README.md) gateway.
|
||||
|
||||
## ROADMAP
|
||||
The emqx_gateway application depends on `emqx`, `emqx_authn`, `emqx_ctl` that
|
||||
provide the foundation for protocol access.
|
||||
|
||||
Gateway v0.1: "Basic Functionals"
|
||||
- Management support
|
||||
- Conn/Frame/Protocol Template
|
||||
- Support Stomp/MQTT-SN/CoAP/LwM2M/ExProto
|
||||
## Three ways to create your gateway
|
||||
|
||||
Gateway v0.2: "Integration & Friendly Management"
|
||||
- Hooks & Metrics & Statistic
|
||||
- HTTP APIs
|
||||
- Management in the cluster
|
||||
- Integrate with AuthN
|
||||
- Integrate with `emqx_config`
|
||||
- Improve hocon config
|
||||
- Mountpoint & ClientInfo's Metadata
|
||||
- The Concept Review
|
||||
## Raw Erlang Application
|
||||
|
||||
Gateway v0.3: "Fault tolerance and high availability"
|
||||
- A common session modoule for message delivery policy
|
||||
- The restart mechanism for gateway-instance
|
||||
- Consistency of cluster state
|
||||
- Configuration hot update
|
||||
This approach is the same as in EMQX 4.x. You need to implement an Erlang application,
|
||||
which is packaged in EMQX as a [Plugin](todo) or as a source code dependency.
|
||||
In this approach, you do not need to respect any specifications of emqx_gateway,
|
||||
and you can freely implement the features you need.
|
||||
|
||||
Gateway v1.0: "Best practices for each type of protocol"
|
||||
- CoAP
|
||||
- Stomp
|
||||
- MQTT-SN
|
||||
- LwM2M
|
||||
|
||||
### Compatible with EMQX
|
||||
Steps guide: [Implement Gateway via Raw Application](doc/implement_gateway_via_raw_appliction.md)
|
||||
|
||||
> Why we need to compatible
|
||||
## Respect emqx_gateway framework
|
||||
|
||||
1. Authentication
|
||||
2. Hooks/Event system
|
||||
3. Messages Mode & Rule Engine
|
||||
4. Cluster registration
|
||||
5. Metrics & Statistic
|
||||
Similar to the first approach, you still need to implement an application using Erlang
|
||||
and package it into EMQX.
|
||||
The only difference is that you need to follow the standard behaviors(callbacks) provided
|
||||
by emqx_gateway.
|
||||
|
||||
> How to do it
|
||||
This is the approach we recommend. In this approach, your implementation can be managed
|
||||
by the emqx_gateway framework, even if it may require you to understand more details about it.
|
||||
|
||||

|
||||
|
||||
### User Interface
|
||||
Steps guide: [Implement Gateway via Gateway framework](doc/implement_gateway_via_gateway_framekwork.md)
|
||||
|
||||
#### Configurations
|
||||
## Use ExProto Gateway (Non-Erlang developers)
|
||||
|
||||
```hocon
|
||||
gateway {
|
||||
If you want to implement your gateway using other programming languages such as
|
||||
Java, Python, Go, etc.
|
||||
|
||||
## ... some confs for top scope
|
||||
..
|
||||
## End.
|
||||
You need to implement a gRPC service in the other programming language to parse
|
||||
your device protocol and integrate it with EMQX.
|
||||

||||

#### How to integrate a protocol to your platform
|
||||
|
||||
### Develop your protocol gateway
|
||||
|
||||
There are 3 way to create your protocol gateway for EMQX 5.0:
|
||||
|
||||
1. Use Erlang to create a new emqx plugin to handle all of protocol packets (same as v5.0 before)
|
||||
|
||||
2. Based on the emqx-gateway-impl-bhvr and emqx-gateway
|
||||
|
||||
3. Use the gRPC Gateway

# EMQX 5.0 CoAP Gateway
|
||||
|
||||
emqx-coap is a CoAP Gateway for EMQX. It translates CoAP messages into MQTT messages and make it possible to communiate between CoAP clients and MQTT clients.
|
||||
|
||||
|
||||
<a id="orgeddbc94"></a>
|
||||
|
||||
## Features
|
||||
|
||||
- Partially achieves [Publish-Subscribe Broker for the Constrained Application Protocol (CoAP)](https://datatracker.ietf.org/doc/html/draft-ietf-core-coap-pubsub-09)
|
||||
we called this as ps handler, include following functions:
|
||||
- Publish
|
||||
- Subscribe
|
||||
- UnSubscribe
|
||||
- Long connection and authorization verification called as MQTT handler
|
||||
|
||||

|
||||
|
||||
### PubSub Handler
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
|
||||
<a id="org55be508"></a>
|
||||
|
||||
### MQTT Handler
|
||||
|
||||
Establishing a connection is optional. If the CoAP client needs to use connection-based operations, it must first establish a connection.
|
||||
At the same time, the connectionless mode and the connected mode cannot be mixed.
|
||||
In connection mode, the Publish/Subscribe/UnSubscribe sent by the client must be has Token and ClientId in query string.
|
||||
If the Token and Clientid is wrong/miss, EMQX will reset the request.
|
||||
The communication token is the data carried in the response payload after the client successfully establishes a connection.
|
||||
After obtaining the token, the client's subsequent request must attach "token=Token" to the Query String
|
||||
ClientId is necessary when there is a connection, and is a unique identifier defined by the client.
|
||||
The server manages the client through the ClientId. If the ClientId is wrong, EMQX will reset the request.
|
||||
|
||||
1. Create a Connection
|
||||
|
||||
Method: POST
|
||||
URI Schema: mqtt/connection{?q\*}
|
||||
q\*:
|
||||
|
||||
- clientid := client uid
|
||||
- username
|
||||
- password
|
||||
|
||||
Response:
|
||||
|
||||
- 2.01 "Created" when success
|
||||
- 4.00 "Bad Request" when error
|
||||
- 4.01 "Unauthorized" wrong username or password
|
||||
|
||||
Payload: Token if success
|
||||
|
||||
2. Close a Connection
|
||||
|
||||
Method : DELETE
|
||||
URI Schema: mqtt/connection{?q\*}
|
||||
q\*:
|
||||
|
||||
- clientid := client uid
|
||||
- token
|
||||
|
||||
Response:
|
||||
|
||||
- 2.01 "Deleted" when success
|
||||
- 4.00 "Bad Request" when error
|
||||
- 4.01 "Unauthorized" wrong clientid or token
|
||||
|
||||
|
||||
<a id="org3d1a32e"></a>
|
||||
|
||||
### Heartbeat
|
||||
|
||||
The Coap client can maintain the "connection" with the server through the heartbeat,
|
||||
regardless of whether it is authenticated or not,
|
||||
so that the server will not release related resources
|
||||
Method : PUT
|
||||
URI Schema: mqtt/connection{?q\*}
|
||||
q\*:
|
||||
|
||||
- clientid if authenticated
|
||||
- token if authenticated
|
||||
|
||||
Response:
|
||||
|
||||
- 2.01 "Changed" when success
|
||||
- 4.00 "Bad Request" when error
|
||||
- 4.01 "Unauthorized" wrong clientid or token
|
||||
|
||||
|
||||
<a id="org9a6b996"></a>
|
||||
|
||||
### Query String
|
||||
|
||||
CoAP gateway uses some options in query string to conversion between MQTT CoAP.
|
||||
|
||||
1. Shared Options <a id="orgc50043b"></a>

## Example
|
||||
1. Create Connection
|
||||
```
|
||||
coap-client -m post -e "" "coap://127.0.0.1/mqtt/connection?clientid=123&username=admin&password=public"
|
||||
```
|
||||
Server will return token **X** in payload
|
||||
|
||||
2. Update Connection
|
||||
```
|
||||
coap-client -m put -e "" "coap://127.0.0.1/mqtt/connection?clientid=123&token=X"
|
||||
```
|
||||
|
||||
3. Publish
|
||||
```
|
||||
coap-client -m post -e "Hellow" "obstoken" "coap://127.0.0.1/ps/coap/test?clientid=123&username=admin&password=public"
|
||||
```
|
||||
if you want to publish with auth, you must first establish a connection, and then post publish request on the same socket, so libcoap client can't simulation publish with a token
|
||||
|
||||
```
|
||||
coap-client -m post -e "Hellow" "coap://127.0.0.1/ps/coap/test?clientid=123&token=X"
|
||||
```
|
||||
|
||||
4. Subscribe
|
||||
```
|
||||
coap-client -m get -s 60 -O 6,0x00 -o - -T "obstoken" "coap://127.0.0.1/ps/coap/test?clientid=123&username=admin&password=public"
|
||||
```
|
||||
**Or**
|
||||
|
||||
```
|
||||
coap-client -m get -s 60 -O 6,0x00 -o - -T "obstoken" "coap://127.0.0.1/ps/coap/test?clientid=123&token=X"
|
||||
```
|
||||
5. Close Connection
|
||||
```
|
||||
coap-client -m delete -e "" "coap://127.0.0.1/mqtt/connection?clientid=123&token=X
|
||||
```

# LwM2M Gateway
|
||||
|
||||
[The LwM2M Specifications](http://www.openmobilealliance.org/release/LightweightM2M) is a Lightweight Machine to Machine protocol.
|
||||
|
||||
With `emqx_lwm2m`, user is able to send LwM2M commands(READ/WRITE/EXECUTE/...) and get LwM2M response in MQTT way. `emqx_lwm2m` transforms data between MQTT and LwM2M protocol.
|
||||
|
||||
emqx_lwm2m needs object definitions to parse data from lwm2m devices. Object definitions are declared by organizations in XML format, you could find those XMLs from [LwM2MRegistry](http://www.openmobilealliance.org/wp/OMNA/LwM2M/LwM2MRegistry.html), download and put them into the directory specified by `lwm2m.xml_dir`. If no associated object definition is found, response from device will be discarded and report an error message in log.
|
||||
|
||||
## Load emqx_lwm2m
|
||||
|
||||
```
|
||||
./bin/emqx_ctl plugins load emqx_lwm2m
|
||||
```
|
||||
|
||||
## Test emqx-lwm2m using *wakaama*
|
||||
|
||||
[wakaama](https://github.com/eclipse/wakaama) is an easy-to-use lwm2m client command line tool.
|
||||
|
||||
Start *lwm2mclient* using an endpoint name `ep1`:
|
||||
```
|
||||
./lwm2mclient -n ep1 -h 127.0.0.1 -p 5683 -4
|
||||
```
|
||||
|
||||
To send an LwM2M DISCOVER command to *lwm2mclient*, publish an MQTT message to topic `lwm2m/<epn>/dn` (where `<epn>` is the endpoint name of the client), with following payload:
|
||||
|
||||
```json
|
||||
{
|
||||
"reqID": "2",
|
||||
"msgType": "discover",
|
||||
"data": {
|
||||
"path": "/3/0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The MQTT message will be translated to an LwM2M DISCOVER command and sent to the *lwm2mclient*. Then the response of *lwm2mclient* will be in turn translated to an MQTT message, with topic `lwm2m/<epn>/up/resp`, with following payload:
|
||||
|
||||
```json
|
||||
{
|
||||
"reqID": "2",
|
||||
"msgType": "discover",
|
||||
"data": {
|
||||
"code":"2.05",
|
||||
"codeMsg": "content",
|
||||
"content": [
|
||||
"</3/0>;dim=8",
|
||||
"</3/0/0>",
|
||||
"</3/0/1>",
|
||||
"</3/0/4>",
|
||||
"</3/0/16>"
|
||||
]
|
||||
}
|
||||
}
|
||||
```

## Feature limitations
|
||||
|
||||
- emqx_lwm2m implements LwM2M gateway to EMQX, not a full-featured and independent LwM2M server.
|
||||
- emqx_lwm2m does not include LwM2M bootstrap server.
|
||||
- emqx_lwm2m supports UDP binding, no SMS binding yet.
|
||||
- Firmware object is not fully supported now since mqtt to coap block-wise transfer is not available.
|
||||
- Object Versioning is not supported now.
|
||||
|
||||
## DTLS
|
||||
|
||||
emqx-lwm2m support DTLS to secure UDP data.
|
||||
|
||||
Please config lwm2m.certfile and lwm2m.keyfile in emqx_lwm2m.conf. If certfile or keyfile are invalid, DTLS will be turned off and you could read a error message in the log.

## Load Plugin
|
||||
|
||||
```
|
||||
./bin/emqx_ctl plugins load emqx_sn
|
||||
```
|
||||
|
||||
## Client
|
||||
|
||||
### NOTE
|
||||
- Topic ID is per-client, and will be cleared if client disconnected with broker or keepalive failure is detected in broker.
|
||||
- Please register your topics again each time connected with broker.
|
||||
- If your udp socket(mqtt-sn client) has successfully connected to broker, don't try to send another CONNECT on this socket again, which will lead to confusing behaviour. If you want to start from beging, please do as following:
|
||||
+ destroy your present socket and create a new socket to connect again
|
||||
+ or send DISCONNECT on the same socket and connect again.
|
||||
|
||||
### Library
|
||||
|
||||
- https://github.com/eclipse/paho.mqtt-sn.embedded-c/
|
||||
- https://github.com/ty4tw/MQTT-SN
|
||||
- https://github.com/njh/mqtt-sn-tools
|
||||
- https://github.com/arobenko/mqtt-sn
|
||||
|
||||
### sleeping device
|
||||
|
||||
PINGREQ must have a ClientId which is identical to the one in CONNECT message. Without ClientId, emqx-sn will ignore such PINGREQ.
|
||||
|
||||
### pre-defined topics
|
||||
|
||||
The mapping of a pre-defined topic id and topic name should be known inadvance by both client's application and gateway. We define this mapping info in emqx_sn.conf file, and which shall be kept equivalent in all client's side.

# emqx_lwm2m
|
||||
|
||||
[LwM2M (Lightweight Machine-to-Machine)](https://lwm2m.openmobilealliance.org/)
|
||||
is a protocol designed for IoT devices and machine-to-machine communication.
|
||||
It is a lightweight protocol that supports devices with limited processing power and memory.
|
||||
|
||||
|
||||
The **LwM2M Gateway** in EMQX can accept LwM2M clients and translate theirevents
|
||||
and messages into MQTT Publish messages.
|
||||
|
||||
In the current implementation, it has the following limitations:
|
||||
- Based UDP/DTLS transport.
|
||||
- Only supports v1.0.2. The v1.1.x and v1.2.x is not supported yet.
|
||||
- Not included LwM2M Bootstrap services.
|
||||
|
||||
## Quick Start
|
||||
|
||||
In EMQX 5.0, LwM2M gateways can be configured and enabled through the Dashboard.
|
||||
|
||||
It can also be enabled via the HTTP API, and emqx.conf e.g, In emqx.conf:
|
||||
|
||||
```properties
|
||||
gateway.lwm2m {
|
||||
xml_dir = "etc/lwm2m_xml/"
|
||||
auto_observe = true
|
||||
enable_stats = true
|
||||
idle_timeout = "30s"
|
||||
lifetime_max = "86400s"
|
||||
lifetime_min = "1s"
|
||||
mountpoint = "lwm2m/${endpoint_namea}/"
|
||||
qmode_time_window = "22s"
|
||||
update_msg_publish_condition = "contains_object_list"
|
||||
translators {
|
||||
command {qos = 0, topic = "dn/#"}
|
||||
notify {qos = 0, topic = "up/notify"}
|
||||
register {qos = 0, topic = "up/resp"}
|
||||
response {qos = 0, topic = "up/resp"}
|
||||
update {qos = 0, topic = "up/update"}
|
||||
}
|
||||
listeners {
|
||||
udp {
|
||||
default {
|
||||
bind = "5783"
|
||||
max_conn_rate = 1000
|
||||
max_connections = 1024000
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
> 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.
|
||||
:::
|
||||
|
||||
## Object definations
|
||||
|
||||
emqx_lwm2m needs object definitions to parse data from lwm2m devices. Object definitions are declared by organizations in XML format, you could find those XMLs from [LwM2MRegistry](http://www.openmobilealliance.org/wp/OMNA/LwM2M/LwM2MRegistry.html), download and put them into the directory specified by `lwm2m.xml_dir`. If no associated object definition is found, response from device will be discarded and report an error message in log.

# emqx_mqttsn
|
||||
|
||||
The MQTT-SN gateway is based on the
|
||||
[MQTT-SN v1.2](https://www.oasis-open.org/committees/download.php/66091/MQTT-SN_spec_v1.2.pdf).
|
||||
|
||||
## 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:
|
||||
|
||||
```properties
|
||||
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.
