Some trivial questions about tinymqtt use.

[mvincm]

Hello,

Thanks for this code. I'm gone use it in my project.

Just a few questions:

1. I need a simple client (not server). Should I run an instance of MQTTClient? How to use it? Should I use object of MQTTClient class? Should I create it before loop_forever (TinyWeb server)?

2. Should it be an object in a separate task (create_task)?

3. I'm asking you very much to give a simple example of use - if you remember of course ;)

Best regards,
MvincM

Hi,

It looks like I've got good example for you (despite project is deprecated, but still good for ideas):

• Create client: https://github.com/belyalov/iot-platform/blob/master/devices/open_neopixel_controller/app.py#L62
• Run it: https://github.com/belyalov/iot-platform/blob/master/devices/open_neopixel_controller/app.py#L134
• Publish message: https://github.com/belyalov/iot-platform/blob/master/devices/open_neopixel_controller/strip.py#L50
• Subscribe / receive message: https://github.com/belyalov/iot-platform/blob/master/devices/open_neopixel_controller/strip.py#L37 and https://github.com/belyalov/iot-platform/blob/master/devices/open_neopixel_controller/strip.py#L99

Regarding running multiple "tasks" you can found one of possible implementations here:
https://github.com/belyalov/iot-platform/blob/master/devices/magic_led_controller/main.py#L114

Thanks for interest in this project as well.. ) It was awhile back ago, hopefully it is working well.

P.S. I used to have 2 DIY devices made using these 2 libraries (NeoPixel and regular LED controllers), they've been working for almost 2 years until we've moved out so I had to deinstall them.. )

Thanks! I will look up in those examples!

Hello.

Sorry for a "short" delay.

About running multiple tasks.

In file https://github.com/belyalov/iot-platform/blob/master/devices/magic_led_controller/main.py#L114 in line 116 we can find

web.run(host='0.0.0.0', port=wport, loop_forever=False, loop=loop)

but run() doesn't accept "loop" argument becaues it doesn't use it and going further in file server.py (https://github.com/belyalov/tinyweb/blob/0b76fc1b3b30e5056716c10be570096b84e6caa0/tinyweb/server.py#L379) in line 379 there is self.loop = asyncio.get_event_loop() - no external argument.

So the question is: Are we have two loops? One main loop and second from webserver object? If we can't point to the main loop (as we do not send the argument "loop") we can't use one loop. Am I correct?

I would be grateful for your help. May be there are two version of server.py (tinyweb project)? Same situation is with mqtt.run() and "loop" argument.

BTW... I'm very close to use your MQTT library (I can send a message to a server with success) but stil fighting with above loop problem.
