cc3000 stopped working?

Post by sketchy »

What was once smooth has stopped. I've double/tripple checked wiring. I turned on DEBUG_MODE in debug.h to (1) ... on...

The last debug statement I get on the serial monitor is:

Hello, CC3000!

RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 1237

Initialising the CC3000 ...
before init_spi()

CC3000: init_spi

CC3000: Finished init_sp

can someone please help let me know if this points to something obvious or has the chip/breakout board stopped working - or suggestions for debugging?

thank you.

Please post clear, detailed pictures showing your soldering and wiring.

Same story for me!
Recently I got my new CC3000 shield from you and successfully played with examples. On the next day the shield stopped working. The power LED and LED 13 on Arduino board blink rapidly on power-on, when CC3000 shield is on top. The output in serial monitor is exactly the same as the user "sketchy" has shown. Somehow I managed to get CC3000 working again (no idea what lead to recovery) and the shield worked successfully whole day, but stopped again in the evening with same symptoms. I enabled debug mode and now I see in the console:

Code: Select all

Hello, CC3000!

RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 1247

Initialising the CC3000 ...
	CC3000: init_spi
	CC3000: Finished init_spi
init
start
	CC3000: SpiOpen	CC3000: WlanInterruptEnable.
	CC3000: Finished SpiOpen
	CC3000: ReadWlanInterruptPin - 001

My pictures with soldering are here.

Igor - indeed - you are seeing what I saw. I did not have permission to view your image though.

Rick - Here are images of my wiring.
http://solarslurpie.imgur.com/all/#

...um not sure if the pictures are "good enough" wiring follows what is here: http://learn.adafruit.com/adafruit-cc30 ... 0-breakout

does this: CC3000: ReadWlanInterruptPin - 001

mean the irq is not being read? (pin 3)...which I have wired but...

@igor - I can't see your pictures
@sketchy - I can't see your pictures either.

You can use the 'Upload Attachments' tab to upload and post photos directly to the forum.

BTW, I use Seeeduino v3.0 board, maybe it does matter.

None of those debug messages necessarily indicate an error.

What sketches are you both trying to run?

Have you downloaded and installed the latest version of the library?

library: 9/25/2013 (assume this is the latest)
sketch: buildtest.ino (ran many times. used board for something else. then put back on with wiring. i assumed either wiring or hw issue..hoping where stopped in library gives clue to what is wrong (considering it goes partially through then seems to get hung in reading IRQ?)

@sketchy - time to start swapping jumpers, I think. Maybe move to a different part of the breadboard, too.

I tried a different breadboard. Different wires. Different Arduino...and bummer...same thing happens. The library seems to be able to talk to the cc3000 to get the tx and rx buffer size - but not get through SPI initialization?

Also - I'll take this opportunity to show just how little I know. I checked the voltage with multimeter and that's all good.

I was hoping the following would check the current (i.e.: i inserted the multimeter probes by cutting a wire and putting one end on each of the probes)...?:

@Sketchy - let's try replacing the CC3000. Please email [email protected] with a link to this thread.

I try to run buildtest sketch from latest version of the library from github.

Also I tried different USB cables, different Arduino's (Stalker and Nano) and tried to use jumper-wires and got same result.

Hey Rick,
THANK YOU. You and the rest of Adafruit are exceptional. I emailed support, support emailed me back immediately with steps to get a replacement. Again - thank you.
