Before today, my core was working just fine. Had some downtime at the office, so I played around writing a few simple cloud-controlled functions, everything was fine. It had previously worked well at my home network as well.
Now, though, I cannot get the Core to connect. I’ve gone as far as factory-resetting it; manually programming the wireless credentials just left it blinking green endlessly.
After using the Android app, it accepts my credentials, and begins flashing fuchsia as it does when it is being reprogrammed, then begins attempting to reconnect. It briefly flashes green, then rapidly flashes cyan for a moment, before sitting on a solid fuchsia light for a few seconds before repeating the loop all over again. Eventually, it will either begin blinking cyan as if it’s lost the connection, or it will just sit on a solid fuchsia light, as it is currently doing. It has done this both at my office and here at home; it’s worked fine at both places before.
I’ve tried to reload the factory firmware via DFU mode, but that only results in dfu_util.exe giving me the message “Opening DFU capable USB device… Cannot open device”
Just in case my description of the light sequence is tough to follow, (long day at work plus a few hours of graduate studies…), I attempted to take a short video to show what I mean.
I’m having the same problem here. I can tell it is connected to WiFi and has been given an IP, but that’s about it. The Core never stops cycling through its various LED colors. This was its first time was out of the box. I tried a factory reset, no change.
Looks like im getting a similar issue as well, up until tonight my core has been able to connect and I’ve been doing plenty of work on it without issue.
I’ve let my core sit and go through the noted color cycle, but I noticed that every so often I get 3 red flashes. From the support docs this indicates that there could be some sort of outage in the Spark Cloud, but there isn’t anything noted from what I’ve seen.
If you guys let your core sit and attempt to connect do you see three red flashes eventually as well?
Hi all - we published a firmware update today with a bug in it, but the issue has now been fixed; if you do a factory reset, it should revert back to normal behavior. Sorry about that!
But even after a factory reset just now, I’m still seeing this problem. Is there anything in particular I need to do beyond factory reset to force it to load the new firmware?
Edit: Went to bed, woke up, everything’s cool now. Thanks again Zach.
using the app #1 would connect to the cloud but not #2
I could not claim #1 so I used USB to get the hex ID (i) and since I was there I also set up the wifi manually (w) then claimed it via spark IDE
#2 would not connect to the cloud from the App. You could see that it was trying to but it failed.
So I tried USB to enter the credentials. It asked for SSID and Password (entered ok) and reverted to switching between the flashing orange and the flashing cyan.
At this point I noticed that #2 did not ask:
Security 0=unsecured, 1=WEP, 2=WPA, 3=WPA2:
Since I was having no luck, and found on the forums that it may sometimes be needed to re-flash the core, I went where angels fear to tread and downloaded dfu-util (brew = 0.5, macports = 0.7) and the zipped stuff from the site, installed gcc-arm as instructed and while I could re-flash, no improvement was forthcoming…
So I can tinker with #1 but was trying to get both up before I try doing something really stupid (sorry - that should read “impressive”).
Set credentials over USB
SSID: Istana_Bahru
Password: ### correct password entered ###
Thanks! Wait about 7 seconds while I save those credentials…
Awesome. Now we’ll connect!
… etc.
I get a fast flashing orange with occasional fast flashing cyan
=== after power cycle ====
cyan slow flash (about 2 second) x 1
green flash (about 3 second) x 1
fast flashing orange with occasional fast flashing cyan
Orange sounds like a bad handshake with the cloud which means there might be some issue with the key on the core.
Are you comfortable installing Spark-cli and attempt to update the key?
If you ever had breathing cyan, this shouldn't be a problem but looking at the symptoms, it's worth giving it a shot!
FLASHING ORANGE (RED/YELLOW)
What’s the Core doing? My Core is flashing yellow/red/orange lights after it connects to Wi-Fi.
What’s the problem? A decryption error occurred during the handshake with the Spark Cloud
