Hello, I have two Photon, I have found an easy example i want to test, but led will not blink: //D7 LED Flash Example int LED = D7; void setup() { pinMode(LED, OUTPUT); } void loop() { digitalWrite(LED, HIGH); delay(1000); digitalWrite(LED, LOW); delay(1000); } I have tried many things …

Did the standard tinker firmware work when you first setup the Photon? What happens after the LED turns magenta? Does it reconnect to wifi (flashing green, then goes to breathing cyan)?

I don’t understand why this is happening. But one off the wall thought. Maybe the pair are confusing each other. Have you tried turning one off, and just working with the other one? Have you been using the pair really close to each other (a couple inches) ? Anyone with thoughts, jump right in here…

@Jack , the way the flash command works, yes, it is possible to have a success report on the flash, without actual success. All the process reports at this time (I believe) is whether or not the device has received the flash image, not whether or not the flash was successful. As to the problems, …
