I’m attempting to troubleshoot an Electric Imp for my lab. Yesterday night it was working just fine, but now I can’t get it to work. No matter the power source, the light won’t blink. It blinked once and then stopped and never again. I’ve seen a similar question here:
However I think I have the imp001 (http://www.amazon.com/WiFi-Environmental-Sensor-LED-kit/dp/B00ZQ4D1TM/) since the kit looks exactly the same and I have the Env tail attached to it.
One thing I noticed is that the Env tail heats up A LOT (honestly this has been my way to realize something is happening in there with energy flow). I thankfully found a usb in my house to plug it in for power, but I also have tried with an Energizer 9 V battery which my lab had soldered it in on the +P/-P.
I don’t have anything to verify the voltage right now on the imp. Any insights on this? The cellphone was paired sucessfully last night and I still have the screen here, along with some tests I run which the device responded. But that was it, nothing today. (curiously enough, i left everything as is other than unplug from the battery.
While I was testing the weather station code on it yesterday, I realized it sampled once or two, then went to sleep and it wouldn’t resurrect afterwards (no matter the delay if 600s or 5s). I wonder if both issues relate.
Edit: I found out that changing the ENV tail to the LED tail makes it work just fine (also without any tail). So I am led to believe there is something wrong with the ENV tail. I also realized the ground pin is slightly bended, and the env tail does heat up a lot. However, I started wondering if it may be an issue with enough energy being supplied. Is it safe to connect the usb to an adaptor to them plug on the wall or would this fry the whole imp?
