Thank you for opening an issue on an Adafruit Arduino library repository. To
|
||||
improve the speed of resolution please review the following guidelines and
|
||||
common troubleshooting steps below before creating the issue:
|
||||
|
||||
- **Do not use GitHub issues for troubleshooting projects and issues.** Instead use
|
||||
the forums at http://forums.adafruit.com to ask questions and troubleshoot why
|
||||
something isn't working as expected. In many cases the problem is a common issue
|
||||
that you will more quickly receive help from the forum community. GitHub issues
|
||||
are meant for known defects in the code. If you don't know if there is a defect
|
||||
in the code then start with troubleshooting on the forum first.
|
||||
|
||||
- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
|
||||
check all of the steps and commands to run have been followed. Consult the
|
||||
forum if you're unsure or have questions about steps in a guide/tutorial.
|
||||
|
||||
- **For Arduino projects check these very common issues to ensure they don't apply**:
|
||||
|
||||
- For uploading sketches or communicating with the board make sure you're using
|
||||
a **USB data cable** and **not** a **USB charge-only cable**. It is sometimes
|
||||
very hard to tell the difference between a data and charge cable! Try using the
|
||||
cable with other devices or swapping to another cable to confirm it is not
|
||||
the problem.
|
||||
|
||||
- **Be sure you are supplying adequate power to the board.** Check the specs of
|
||||
your board and plug in an external power supply. In many cases just
|
||||
plugging a board into your computer is not enough to power it and other
|
||||
peripherals.
|
||||
|
||||
- **Double check all soldering joints and connections.** Flakey connections
|
||||
cause many mysterious problems. See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
|
||||
|
||||
- **Ensure you are using an official Arduino or Adafruit board.** We can't
|
||||
guarantee a clone board will have the same functionality and work as expected
|
||||
with this code and don't support them.
|
||||
|
||||
If you're sure this issue is a defect in the code and checked the steps above
|
||||
please fill in the following fields to provide enough troubleshooting information.
|
||||
You may delete the guideline and text above to just leave the following details:
|
||||
|
||||
- Arduino board: **INSERT ARDUINO BOARD NAME/TYPE HERE**
|
||||
|
||||
- Arduino IDE version (found in Arduino -> About Arduino menu): **INSERT ARDUINO
|
||||
VERSION HERE**
|
||||
|
||||
- List the steps to reproduce the problem below (if possible attach a sketch or
|
||||
copy the sketch code in too): **LIST REPRO STEPS BELOW**

Thank you for creating a pull request to contribute to Adafruit's GitHub code!
|
||||
Before you open the request please review the following guidelines and tips to
|
||||
help it be more easily integrated:
|
||||
|
||||
- **Describe the scope of your change--i.e. what the change does and what parts
|
||||
of the code were modified.** This will help us understand any risks of integrating
|
||||
the code.
|
||||
|
||||
- **Describe any known limitations with your change.** For example if the change
|
||||
doesn't apply to a supported platform of the library please mention it.
|
||||
|
||||
- **Please run any tests or examples that can exercise your modified code.** We
|
||||
strive to not break users of the code and running tests/examples helps with this
|
||||
process.
|
||||
|
||||
Thank you again for contributing! We will try to test and integrate the change
|
||||
as soon as we can, but be aware we have many GitHub repositories to manage and
|
||||
can't immediately respond to every request. There is no need to bump or check in
|
||||
on a pull request (it will clutter the discussion of the request).
|
||||
|
||||
Also don't be worried if the request is closed or not integrated--sometimes the
|
||||
priorities of Adafruit's GitHub code (education, ease of use) might not match the
|
||||
priorities of the pull request. Don't fret, the open source community thrives on
|
||||
forks and GitHub makes it easy to keep your changes in a forked repo.
|
||||
|
||||
After reviewing the guidelines above you can delete this text from the pull request.

# Adafruit MQTT Library Arbitrary Data Publish Example
|
||||
|
||||
This example illustrates publishing an arbitrary data packet using the Adafruit MQTT library to an MQTT feed which can then be parsed by the included python subscriber client. Possible usage cases include adding metadata (collection time, sensor info etc) to a datapoint.
|
||||
|
||||
|
||||
|
||||
My motivation for this was wanting to be able to include metadata to a post.
|
||||
Specifically, I was playing around with a [Teviso RD3024 radiation sensor](http://www.teviso.com/en/products/radiation-sensor-rd3024.htm), and a salvaged Americium radiation source from a smoke detector, at varying distances from the sensor. I wanted a way to associate the collection time, and distance between the source and sensor with the actual radiation reading itself.

|
||||
|
||||
## Installing and configuring Mosquitto broker (minimal working setup):
|
||||
|
||||
####_Installing on Raspberry Pi/Linux:_
|
||||
|
||||
```bash
|
||||
sudo apt-get install mosquitto
|
||||
cd /etc/mosquitto/
|
||||
#See "Configuring Mosquitto Broker below"
|
||||
```
|
||||
|
||||
####_Installing On a Mac:_
|
||||
```bash
|
||||
brew install mosquitto
|
||||
cd /usr/local/etc/mosquitto
|
||||
#See "Configuring Mosquitto Broker below"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
####Configuring Mosquitto broker
|
||||
```bash
|
||||
sudo nano mosquitto.conf
|
||||
```
|
||||
Now we have to enable a password file to correctly interface with the Adafruit MQTT library. Scroll about two thirds of the way down until you see:
|
||||
|
||||
```bash
|
||||
# -----------------------------------------------------------------
|
||||
# Default authentication and topic access control
|
||||
# -----------------------------------------------------------------
|
||||
```
|
||||
|
||||
You should see `#password_file` about a paragraph after that.
|
||||
Change
|
||||
|
||||
```bash
|
||||
#password_file
|
||||
```
|
||||
|
||||
To
|
||||
|
||||
```bash
|
||||
password_file pwfile
|
||||
```
|
||||
|
||||
Now `ctrl-x` to save and exit.
|
||||
|
||||
You're almost done! We just have to create and populate the password file we just configured. The default user info is:
|
||||
* **Arduino Subscriber:**
|
||||
* Username: TestUser
|
||||
* Password: TestUser
|
||||
|
||||
* **Python Subscriber:**
|
||||
* Username: TestPy
|
||||
* Password: TestPy
|
||||
|
||||
```bash
|
||||
touch pwfile #create the password file
|
||||
mosquitto_passwd pwfile TestUser #Enter and confirm password when prompted
|
||||
mosquitto_passwd pwfile TestPy #Enter and confirm password when prompted
|
||||
```
|
||||
|
||||
####Running Mosquitto broker
|
||||
Now run Mosquitto broker to allow Arduino publisher and Python subscriber to communicate
|
||||
|
||||
```bash
|
||||
mosquitto
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Using Example Python Subscriber:
|
||||
|
||||
####Installing Python subscriber
|
||||
Install dependencies if you haven't already
|
||||
```bash

cd ../Adafruit_MQTT_Library/examples/mqtt_arbitrary_buffer/python_subscriber
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
|
||||
####Installing Python subscriber
|
||||
Run python script with default values and watch your parsed data print out.
|
||||
```bash
|
||||
python subscriber.py #Add -h flag to see modifiable options
|
||||
```
|
||||
|
||||
Assuming that the Mosquitto broker is running in the background and the Adafruit_MQTT client (Arduino) is publishing, you should see the example data print out every 10 seconds.
|
||||
|
||||
```bash
|
||||
MQTT: Connection successful
|
||||
Connection successful
|
||||
Subscribed to /feeds/arb_packet
|
||||
Received char Array: "Hello!", val1: -4533, val2: 73102, val3: 3354...
|
||||

Adafruit MQTT Library Retain Flag Example
|

|
||||
This example demonstrates use of the retain flag when publishing messages.
|

If retain is set, the MQTT broker will store the message. When a new
|
||||
client subscribes to the topic, the retained message will be republished
|
||||
to that client. This is useful for configuration messages and 'last known
|

good' values.

Adafruit MQTT Library Arduino Yun Example
|
||||
|
||||
Make sure your Arduino Yun is connected to a WiFi access point which
|
||||
has internet access. Also note this sketch uses the Console class
|
||||
for debug output so make sure to connect to the Yun over WiFi and
|
||||
open the serial monitor to see the console output.
|
||||
|
||||
Works great with the Arduino Yun:
