We now have preliminary imp004m samples available; if you need some, please contact sales@electricimp.com. These do not have the final antenna design on them, as we are doing some final tunings before regulatory testing, but they work pretty well - so they are only usable for prototyping purposes, not production.
I put together two of an IMP004m pcb design I had reviewd by electric imp and in both cases the leds blink a nice yellow light on assembly. Howver, when I blinked them up, the app could not discover the devices and now the led is a very faint but steady red. The blink up app says the blink up failed. I tried several times but without the leds blinking I am not sure what state the IMP004m is in, and power off/on does not seem to reset themback to their rigianl yellow blinky state. Any iudea what I could be doing wrong? Thanks, Kris
I didn’t get any successful blink ups so no mac addresses,. I didn’t pre-program the SPI flash if that’s what you mean. I still have one that I didn’t try to blinkup and it is flashing yellow at one-second intervals like the other ones before blinkup. You didn’t reveiw the design someone else at electric imp did, but I can’t remeber his name. Please PM me at onehorse@earthlink.net (I switched computers and all of my e-mail contact infor is inconveniently located, let’s say) and I will send you the design files. Thanks,
You do need to pre-program as the imp004m design guide says, though if an image isn’t found you should see the SPI flash error - was the blinking amber you saw a standard “no settings” blink, or could it have been a SPI flash error blink?
