CC3000 hangs on AP/SSID scan

[buckinkb]

Hi there,

I get this output, and then nothing:

Hello, CC3000!

RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 1219

Initialising the CC3000 ...
Firmware V. : 1.24
MAC Address : 0x08 0x00 0x28 0x57 0x98 0xFC
Started AP/SSID scan

I've rechecked pins (for soldiering errors), and the SSID/Password is correct.

I'm using the arduino Uno (most likely a revision 1).

Other information:

1. I'm in an apartment building, so there are 30+ wifi connections available (will this cause a delay in searching?)
2. I've chosen the right security key (WPA2) and tried WPA & WEP just to be sure
3. I've looked back over the solder points, and all look okay.

If you think the board is soldered good enough , Uncomment from this

Code: Select all

// Optional SSID scan
   //listSSIDResults();

to this

Code: Select all

// Optional SSID scan
   listSSIDResults();

and see if you see anything AT ALL!
Not to be mean , but your soldering skills good use a refresher course.

My code looks like:

/* Optional: Get the SSID list (not available in 'tiny' mode) */
#ifndef CC3000_TINY_DRIVER
listSSIDResults();
#endif

Which means listSSIDResults should have run yes? I changed to:

listSSIDResults();

Also with no luck.

Any other thoughts?

YOUR SOLDER CONNECTIONS!

[buckinkb]

I have now redone all the connections (no they are not perfect, but are definitely connected as far as I can see.) and the same thing is happening.

Your 5v ,3.3V pins and the Dig pins 3,5,10,11,12,and 13 are very important!
Make sure that you check out the adafruit soldering Tutorial.

What sketch are you loading? what arduino board/version are you using?.....

I looked at those pins, and they seem to be soldered nearly perfectly, and I fixed errors, for now the fourth time.

I'm using the buildtest sketch from http://learn.adafruit.com/adafruit-cc30 ... y-software

I'm using the original arduino board (r1).

What microcontroller do you have in the Arduino? We've seen some issues where the ATmega168 doesn't have enough SRAM to hold all the data a sketch needs.

[buckinkb]

hmm I have the atmega328-pu but I've narrowed the problem to a board issue. I tried with a different arduino (r3) and everything worked. Is there somewhere that lists incompatible versions of arduino boards? I will try upgrading the firmware

[adafruit_support_mike]

That does sound like a bootloader issue, though I'm not sure what it would be.

The good news is that writing a new bootloader isn't difficult if you have two Arduinos, and I don't know of any downside to running the latest version.
