Hi,

I'm not having much luck getting the data to Plot..

Looking at https://plot.ly/streaming , it seems a username / apikey is needed, but I don't see where that's done in the code. For example, a socket connection is made to IP 0x6b15d6c7 (via BsdTcpClient), where the socketIDD is returned. However, shouldn't the POST to /clientresp (in order to create an empty graph w/token), be done beforehand? It seems to be made afterwards, and it's commented out!

The only (uncommented) 'POST' appears after the socket connection, and doesn't send the /clientresp nor username/apikey:

Are the three buffers (PLOTLY[], initPlotly[], initStream[]) meant to be uncommented and sent? Something like :

I think my hardware is ok, since a couple TI SDK examples work fine (getting_started_with_wlan_station, http_client, http_server, and tcp_socket). But perhaps the Plot.ly API has since changed?

I'm using an MSP430-EXP430F5529LP Rev1.6 with a CC3100BOOST Rev.4.0 (flashed with SP 1.0.0.10-2.5.99.2-Beta), and compiling with CCSv6.1.0.00104 .

Very cool!

I'm just starting to learn programming (got my arudino less than a month ago!), and plotting sensor data (from my worm farm) to the net is EXACTLY what I'm hoping to do! Do you think this can work with an arudino and a CC3100 shield?

Just to see if I understand the overall concept, is the idea that the microcontroller establishes a connection to the plot.ly servers (similar to temboo?), after that it's a matter of how fast you can post sensor data to plot.ly, is that correct?

I've read that using udp (instead of tcp) is best for maximizing data transfer.. does this use udp or tcp? What's the fastest you've been able to send data?

Thanks!

Ben

Wow, great project, and very detailed!

I had missed this reading this, but just noticed the link to it in your CC3100/3200 review!

Very good post.

You provide a lot of useful information that I hope I can use in my own applications.

Thanks
