Hi, I was able to flash the device with “Blink An LED” program. That worked!
I next flashed the device with Web-Connected LED, over the air, and I see my device programmed.

I downloaded the app for my iPhone, I pressed D7 “to write” and received the following message:
Device Error ‘Error communicating with device - Request failed: not found (404)’.
Can anyone help me?



The Particle app requires the tinker firmware to function correctly.

Using other examples will not toggle the led. What you can do is to add in the code for tinker firmware to the web-connected led example for that to work :slight_smile:
