I have also been having issues with the Xively sketch. In my case the CC3000 consistently connects to my AP, and connects to Xively. The issue that I have is after some random number of connections to Xively (1 to 15) the client.print(data); line in the sketch will hang.

The quick hack to get around this issue could be to simply put a watchdog around the command, but I am using a MEGA2560, which has issues with the watchdog timer.

I have tried to check the status of client.connected() just prior to the client.print(data); and it still returns true but subsequently hangs on the print.

Lax.ste, can you at least post the hardware and firmware versions of your DIR-655?

Thanks!

I apologize for the delay. I have hardware version A4, firmware 1.21 (it's been working so haven't felt the need to update). I've attached images from the setup pages. All of the app specific routing, port forwarding etc are all stock with no changes or specifics.

Hope this helps!

You have a newer DIR-655 and I fear mine (V2) has issues. I will need to buy a new router but which one is the question! I posted a thread asking what routers others have successfully used but no one had replied yet.

Thanks!

I've had surprisingly good luck the dir-655 that I have. I had an older d-link model that needed reset every few days but this new one usually runs a couple of months before needing any attention.

I just bought a really well rated Trendnet AC1750 router and will be testing it soon. I will post my results.

Well, I am happy to report that the DNS lookup problem :mrgreen: went away as soon as I installed my new Trendnet router. There is obviously something weird about the Dlink DIR-655, hardware V2, firmware 1.37NA that is not working with the CC3000.

:mrgreen:

Glad to hear it's working out for you. A bit worrysome that it won't work across all wifi connections.

I bought a CC3000 Breakout Board, when I tried the buildtest but it hangs at

Code: Select all

listSSIDResults()
I tried different boards, but with no luck. I have attached the circuit and serial log, could someone help?

Serial Log
Hello, CC3000!

RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 1261

Initialising the CC3000 ...
Firmware V. : 1.24
MAC Address : 0x08 0x00 0x28 0x57 0x96 0x7F
Started AP/SSID scan

After this there is no log and the sketch hangs.

That's odd that you're not seeing the device scan for SSIDs. If you comment out this line in the buildtest setup:

Code: Select all

/* Optional: Get the SSID list (not available in 'tiny' mode) */
#ifndef CC3000_TINY_DRIVER
  listSSIDResults();
#endif
So it skips the SSID scan, like:

Code: Select all

/* Optional: Get the SSID list (not available in 'tiny' mode) */
#ifndef CC3000_TINY_DRIVER
  //listSSIDResults();
#endif
Then run the sketch, does it get further? Just want to work back a bit to figure out exactly what's getting stuck.
