I just got my Spark Core (chip antenna) this weekend. So far I’m having some trouble…
At home: Tried setting it up with my iPhone and it just started blinking green. Reset to factory default, tried setting it up with USB, and it just kept blinking green. I’m thinking it might be because I use WEP at home, but it was too late to try changing the router to WPA. (Is WEP as seriously not usable as the serial connection implies?)
At work: Tried it with iPhone and USB, but all I got was cyan for a sec then the green-to-red blinking. We have no security for wireless here so WEP shouldn’t have been the issue. I reset the memory, went back to factory defaults, made sure port 5683 was open (hooray for being IT), checked the status of the Spark.io servers (up), but never got better than green-to-red.
I haven’t tried reflashing the firmware (ugh) yet so maybe that’ll fix the issue. However, I’m curious if there’s any way to make sure the hardware is working. My package arrived Saturday and was outside in a mailbox until Sunday. I feel like the different flashes (green at home, green-to-red at work) means the wifi is okay, but I’d like to rule that out if possible.
