2 Try
comcat@jackslab:/work/nodejs$ npm install coap-cli -g
coap-cli@0.3.0 node_modules/coap-cli
├── commander@2.0.0
├── through2@0.4.2 (xtend@2.1.2, readable-stream@1.0.33)

CoA
3 libcoap
#$ git clone git://git.code.sf.net/p/libcoap/code libcoap-code $ git clone git://github.com/obgm/libcoap.git libcoap-code $ cd libcoap-code $ ./autogen.sh $ ./configure --disable-examples $ make $ sudo make install
Build in other platform:
- Contiki
If you have cloned the sources via git, you need to run ./autogen.sh to generate the build scripts. This step is optional when a source archive is used.
Next, say ./configure --with-contiki to prepare the Makefiles required to build libcoap as Contiki app. To make this work, libcoap usually is unpacked in the directory contiki/apps.
- LwIP
Using libcoap with LwIP requires a hand-crafted Makefile. Please refer to examples/lwip/Makefile to see how this is done.
- TinyOS
The usage of libcoap with TinyOS is documented in the TinyOS Wiki.
4 MQTT
4.1 Server
$ npm install mosca bunyan -g
4.2 Client
$ npm install MQTTClient
$ cat cli.js
#! /usr/bin/env node
var MQTTClient = require('MQTTClient').Client;
// if you don't assigned a client_id, will automatically assigns one
var options = {
client_id: 'noduino_test_01'
}
var client = new MQTTClient('101.200.202.247', 1883, options);
client.connect(function () {
// do something if connect success
console.log("connect ok!");
});
