Unable to connect to Wifi (blinking green) usually a CC3000 driver issue use particle-cli and run particle flash --usb cc3000 in DFU mode it will blink magenta and eventually revert to yellow next particle flash --usb tinker now setup wifi credentials using particle serial wifi Very old Spark c…

I was able to fix this by Putting the core into DFU mode Running particle flash --usb cc3000 -v Putting the core into DFU mode (again) Running particle flash --usb tinker -v

Weird as all Mac OSx ports are USB 3.0 and i never had issues.

It could have to do with how the platform (Windows vs OSx) handles USB ports. (Warning: this is unverified speculation. . .don’t write a book based on this post :grin:) It’s very possible that OSx classes all USB ports under the same class, and Windows uses a different class for USB 3.0 ports. If…

Thank you for the article. I’m experiencing connectivity issues and the blinking green. I am able to flash --factory tinker and --usb tinker successfully but when I flash --usb cc3000 I get the following error: Sara$ particle flash --usb cc3000 Found DFU device 2b04:d006 Error writing firmware...no…

I’ve verified that I do have the cc3000 update binaries in /usr/local/lib/node_modules/particle-cli/binaries/ as well as a new copy that I have placed in the directory I am working out of… Still no dice.

You have a photon and it is using a BCM43362 Wifi module so cc3000 patch doesn’t apply. Can you tell me what is wrong with your Photon?

:frowning: I was able to connect the Spark to my wifi access point and claim it only once (and only after I rebooted the AP itself). After that i’ve never been able to go past the green blinking. I’ve tried to patch the CC3000 but i get the error message Cannot open DFU device 0a5c:21e2 Error w…

hmmm… Can you do the following: Place the Core in DFU mode Download https://github.com/spark/particle-cli/blob/master/binaries/cc3000-patch-programmer.bin Run the command: dfu-util -d 1d50:607f -a 0 -s 0x08005000 -D cc3000-patch-programmer.bin Wait for it to download and blink magenta and eventu…

Ok, i’ve tried the steps on another machine (Windows 8.1 and only USB 2.0) and i’ve managed to flash the board. Now it seems to be connected, hope it will keep working :smile: Thanks @kennethlimcp for your help.

I’m having the same blinking green problem, after having successfully connected my (original kickstarter) core ONCE. I’m on a Win10 system, and there’s a hint in the last few posts that this may be a problem. I will follow the advice given and see if it helps. One copy-edit point: the recipe for …

The CC3000-patch did not fix my problem (although, unlike the previous poster, I am still running on a Win-10 system, with USB 2.0 ports, I might add). I’ve re-flashed everything I’ve been told about, and reloaded Tinker countless times, but no luck. Interestingly I have a Photon that I bought (al…
