new to Photon, i succeeded to register my device and the first days could happily play with falshing code to my photon. Now i attached the Sparkfun IMU, followed the instructions to write a sample firmware with “SparkFunLSM9DS1” and could flash the code to my photon.
now it breathes cyan, but ouputs always "“Failed to communicate with LSM9DS1.” on Serial.
I cannot flash new code or such anylonger (via WebIDE or particle-cli). it keeps breathing…
pressing SETUP & MODE does not change anything…
How can i reset my photon?
