@Dave Can you please help !!
I have had the spark core for couple of weeks now, it was working perfectly fine (was able to connect to wifi, flash a program etc).
The core is now flashing green (indicating that its trying to connect to internet) and doesn’t progress further. I’ve followed the troubleshooting guidelines with no luck (powering off & on, rebooting the core & clearing its memory, factory reset). I have not changed any of my wifi settings.
Below is the code that I had used the last time the Spark Core was connected to wifi.
@kennethlimcp I too wish to continue on the same thread, but this is a new problem and not the same issue. Previous thread was regarding a problem of flashing code to the Spark Core from web IDE when there was wifi connectivity to the Spark core. Here I am unable to connect Spark core to wifi in the first place.
I think you are having the continuation of the same problem. I have tried this code (with 1 second and 5 second delays) and due to the bug, it blocks further over-the-air updates very effectively.
I was able to get my core back online by doing a factory reset, after that everything is fine until I run this program again.
@bko Factory reset helped me to get the core online many times but not anymore. Doing a factory reset now, doesn’t seem to progress any further than flashing green led.
I would make sure you do a factory reset from power-off and see if that makes a difference. I have also had to do back to back factory resets–I have done a lot of crazy things to my core including over-writing program memory and I have never bricked it! You just need to be persistent.
@bko, do you think applying a CC3000 patch or performing a deep update would help ? (I’ve bought this core about 4 weeks back, so not sure if a deep update would really help).
Cores from 4 weeks likely already have the patch applied but you can’t tell from the outside, only from the software side. The CC3000 patch will help in general but I don’t think it has anything to do with your current difficulties. You would have to apply it over USB if you cannot do over-the-air updates yet.
I think, generally speaking there’s no problem caused by a firmware you loaded or an OTA flash that can’t be solved by a factory reset.
Here’s a video that shows the process just in case:
I also recommend switching up your USB cable / power supply if everything else is the same, a bad cable / not enough power can prevent the core from connecting.
@Dave, Sorry for the late reply, I saw the factory reset video (several time) and followed the instructions precisely and it doesn’t help. Regarding the power supply connection, I have tried with two cables (including the one supplied by Spark) and it doesn’t work either.
I am not sure what else to do, Can I get a replacement ?
