So my spark has been deployed for a few months now, monitoring the coffee in our office.
Out of the blue the Spark just started flashing green the past day or two. The wifi is still working, the password hasn’t changed. But the spark can’t connect. I took the spark off the breadboard and tried all the suggestions in this thread, and still no luck. To be more specific I tried:
- Factory reset, re-enter wifi credentials
- Factory reset, DFU mode -> cc3000 firmware update -> spark_tinker.bin upload -> re-enter wifi credentials
Still no luck. Flashing green. Can someone help me troubleshoot this?
@kennethlimcp I used the one in the cc3000 repository here. I will try the one you linked, as it appears to be different.
Updated that firmware, then followed up with Tinker. No dice…still flashing green after entering wifi creds.
@osman, are you using CLI? If so, you can get the latest CC3000 patch by doing:
spark flash --usb cc3000
You may also want to update the bootloader though it is only required for the new wake-on-pin modes of Spark.sleep().
Yeah, that didn’t help either. Using spark-cli 0.4.94
@osman, has anything changed outside the Core like your wifi router/AP or channel or a new router/AP? Have you tried bringing the Core closer to your AP?
I had that problem with an original core so I reflashed the cc3000 then tinker and reset the wifi credentials via the Android app.
AFAIK nothing has changed, but here at the office the IT department could have changed something. I will say that it is very unlikely the router changed, and I know the wifi creds didn’t change. Maybe I’ll take it home and try to connect it there.
Nope, no luck at home either. Tried both WPA and WPA2. I think the wifi is fried or something.
Trying to connect to my phone’s hotspot is failing as well. I am going to e-mail support. Thanks for all your help folks.
I’m having a similar issue. Just got mine so I’m not entirely sure how it’s supposed to work, but I haven’t been able to set up via smart connect at all, and I can get it to connect to wifi via usb, but trying to put on the cc3000 firmware sets it in a constant flashing green mode that I need to reset to fix.
If you find out the source, please post.
I ended up emailing support and got a replacement.
