The Internet of Holiday Lights RoadTest Plus

Many thanks sir. Appreciate it.

Your last video up looked great and complete, well done

I was able to get a video up presenting the project but not sure if it shows up good or bad. I did all I could.

10 minutes at[Dynamic Living-Room Lights] The project Summary and Demo Video

As I said in my above post, I am happy DoctorCDF allowed the extra time as with all the hard work everyone has put in it would be a shame to miss some of it due to technical difficulties, I hope you where able to get it all uploaded now

Peter

Hello Peter Sir,

I ran into a loads of problems with the uploads here because apparently there have been policy changes at my ISP and their service has totally messed up. It took 6 1/2 hours to get a 10 minute video up and then YouTube started fussing about the content etc.

I am very greatful to @doctorcdf for the extension in deadline and apologize for the inconvenience caused.

Many thanks again,

Sincerely,

IP

no problems been seen reported in the community that I have observed or experienced by me but it is nice to see some latitude with the final entries as so many people have put so much effort into this one, would be a shame to miss the final entries due to a technical issue

Peter

Hi -

We've had reports of technical difficulties uploading videos - as a result, we'll give a 24 hours grace period to the finalists should they experience these problems in their locale.  Thanks again.

Best Regards, Christian

My road test review can be found in this blog post:

Internet of Holiday Lights: Road Test Plus review

Hi Peter,

I've used MQTT on the CC3200 with the PubSubClient library and Energia in the In the Air Design Challenge.

You can find the Energia example here: Creating an IoT-connected sensor with Energia & MQTT | Energia

Could always be a back-up plan

Hi Benjamin  kartben

I have been working on getting your sample / example code for PAHO on the CC3200 up and running (From here Paho - Open Source messaging for M2M

and here

MQTT on the TI CC3200 LaunchPad thanks to Paho em...

as I want to include some launch pads in the Holiday Light project

I have all the code added to the OOB project but it is alluding me as to how it will connect to the local wan or internet as that project seems to be an access point for connecting from a smart device or something to the card and I can not seem to find a way to have it establish the connection outbound

you did not cover setting up the SSID or password etc for the WIFI and I can not find info from TI to do it either so if you would be so kind to let me know it would be appreciated

Thanks

Peter

Excellent, what a life saver

The documentation is not easy to follow and there using a few techniques in the library I'm not too familiar with

Thanks

Looks like Jan got it nailed

Peter

Robert Peter Oakes , found it.

md.topicName.lenstring.data contains the characters

md.topicName.lenstring.len contains the number of characters.

I did a quick test with this code:

  int i;

  for (i = 0; i < (md.topicName.lenstring.len); i++) {
    printbuf[i] = md.topicName.lenstring.data[i];
  }
  printbuf[(md.topicName.lenstring.len)]=  '\n';
  printbuf[md.topicName.lenstring.len + 1]=  0;




  Serial.print(printbuf);

My holidays are over today, and the Christmas Wreath of Things is finished.

Thanks all, I enjoyed this roadtest a lot.

I'm trying to see if it's available as md.topicName.cstring

hold on...

Robert Peter Oakes,

     Assuming you are using V 1.9.1, The API for the callback shows:

Subscription Callback

If the client is used to subscribe to topics, a callback function must be provided in the constructor. This function
 is called when new messages arrive at the client.

The callback function has the following signature:
 void callback(char* topic, byte* payload, unsigned int length)
Parameters
topic – the topic the message arrived on (char*)
payload – the message payload (byte array)
length – the length of the message payload (unsigned int)

Internally, the client uses the same buffer for both inbound and outbound
 messages. After the callback function returns, or if a call to either publish
 or subscribe is made from within the callback function, the topic
 and payload values passed to the function will be overwritten. The application
 should create its own copy of the values if they are required beyond this.

    So I cannot see why you do not have the first parameter being the specific topic.

Hope this helps,

Clem

Have a question, maybe  kartben   if you could help or anyone else who may have figured out how to do this

using the Eclipse.org library for Arduino or more specifically

#include <MQTTClient.h>

then later

  rc = client.subscribe(topic, MQTT::QOS0, messageArrived);

"messagearrived" being the handler for messages

how does the "MessageArrived"  routine

  rc = client.subscribe(topic, MQTT::QOS0, messageArrived);

know what the topic is, all attempts so far have not printed or provided the topic name,

If I use the standard mosquito subscription under Linux I simply subscribe with a -v in the command line for a verbose response but of course that's not going to work on Arduino

If you subscribe using a wild card so for example topic = thebreadboard\# and I publish both thebreadboard\temp=35 and publish thebreadboard\humidity=35, how do you determine the Topic for the message that arrives?,

I can do this with the PubSubClient.h library but so far the eclipse library has eluded me for this

using

void messageArrived(MQTT::MessageData& md)
{
  MQTT::Message &message = md.message;
  MQTTString mytopic = md.topicName;

does not work, neither does

void messageArrived(MQTT::MessageData& md)
{
  MQTT::Message &message = md.message;
 char* mytopic[50] = md.topicName;

Help would be appreciated, the second example may be a bit off but you get the idea

Feeling Awesome after getting selected thanks doctorcdf and Element14 for making these holidays the best.....

These minions inspired me to give them their voice in the holiday IoT project.. Check this out..
