Raspberry Pi PicoW MQTT-GPIO With Node-RED

This will require the umqtt.simple library on the PicoW,

You can install this with upip by running:

import upip
upip.install('umqtt.simple')

If you use a public MQTT broker such as test.mosquitto.org you should change the prefix value in line 8 of the micropython from MYNAME to something unique or you may recieve other peoples commands

Making API Requets using JWT and HTTPie

HTTPie is AWESOME! if you're still using cURL do yourself a favor and get this https://httpie.org/

Here's a quick guide to make requests to the nexmo API that need to be authenticated with JWT and have a JSON request body.

You will need:

  • The Nexmo CLI installed
  • The private key for your application stored in a local file named private.key
  • The applicaiton ID of your applicaiton
  • The payload of the request in a file called request.json (see example)
