@YazIdo I think this may be an error associated with an accumulating number of open sockets. I got the same OSerror: 23 after running the MQTT example for the 8th time and beyond. A soft reset does not clear this, but powering on/off does clear it - and it works again, at least for the first 7 times. I fixed this problem by adding one line at the very end of the MQTT example. client.disconnect()

Was this issue resolved? Having same issue, same code!

As Alex says it's an external library. The file needs to be present alongside your boot.py and main.py or in one of the folders in your search path. So when you don't have the mqtt.py file it gives that error.

@prakash If your question is how to create webpage and access data in mysql then this is not proper forum for such info. but - look at this detailed tutorial with PHP technology https://www.ibm.com/developerworks/linux/tutorials/l-php/index.html You can use any other method like .net, java...

@bucknall just posted about sending images over MQTT, perhaps one for another Corner?

Hello, i am trying very hard to subscribe to a topic and actually receive something. I am using the integrated client on the AWS side to debug. i am observing that i am successful when it comes to publishing topics. It works well. If i subscribe to a topic i just do not receive anything at all. I have tried with both simple and the guide in the pycom documentation. I suspect at this point a misconfiguration from the side of AWS. I have permission in my policy to subscribe to any resource. Subscription itself works. No messages are ever displayed though. Callback is never called. any help is appreciated!

I am waiting an ublox Neo module to try this project. Very interesting

The freeze with gc.collect seems to be a bug in the firmware. @daniel is already working on it : https://forum.pycom.io/post/4219
