Can anyone import the MQTT library from Arduino into XOD? This Protocol is now very relevant in the Internet of things. This module would be very helpful in implementing the Internet of things with XOD.
Yeah, it will be nice. BTW, what library are you talking about? I found several MQTT libs for Arduino.
I wonder, what’s your most popular scenario of using an MQTT broker? I mean, what kind of projects you’re interested in. Is it a sensor network or, maybe, a remote control for some actuator?
I’d also be very interested in an MQTT Lib and willing to help. Although i have literally no experience in C / C++.
But i guess i could get into it.
If we would collaborate on it - maybe we can get it done.
<PubSubClient.h > the library works well on Arduino.
The MQTT makes it easy to integrate any device into a smart home by type Majordomo or Domoticz (I personally collect leak sensors with sensor modules from esp8266 (but there are no deep sleep libraries and EEPROM in XOD) and server-side value processing (OrangePiPC).
How could we proceed with this?
I was recommended paho
Has you heard of it already?
@nkrkv i am going to plan an IoT system using MQTT. Basically it is going to be a network of several controllers for a heating system which is meant to be controlled remotely via MQTT.
So, can anybody of you can give me a hint on how i can start to implement for example PubSubClient.h into XOD? Is there any kind of documentation i can use to start porting the library?
Not a big help, but the 1st step will be to copy the header file into the XOD install (usually
<USER>\AppData\Local\Programs\xod-client-electron\resources\arduino-libraries). This will need to be repeated each time you re-install or upgrade XOD (there are on-going discussions about how to make this part easier).
The next step is to determine how the calls available in the header file should map to XOD nodes. If there is any one-time initialization that doesn’t need data passed to later calls, you might be able to put it in a separate node; otherwise you may need to put initialization in each node and store the data in State. The library gweimer/ir-remote/ir-read is a fairly trivial example of doing the latter. Since specifying port is tied to the initialization, initialization is only done if the port has not been stored, or it has been changed. Various function calls provided by the IRremote headers are then used to perform the desired action(s).
The built-in nodes for Real Time Clock (search for RTC to find the read/write nodes) provide another example that is probably closer to what you want to do as far as designing nodes for communication, but it uses I2C calls rather than header files.
this is big help for me.
Thank you very much as i got a clue on how to start.
I already was shown the ongoing decision process on github by nkrkv.
Anyways, thanks a lot again. I can dig deeper into this stuff.
