After using the core some days after a programming sesion for testing different codes I was surprised by code flashing fails. I tested a serial lcd connected to TX, GND, 5V. My test code worked fine and one xively code too.
But now I can’t connect the core to the cloud, lighting solid magenta.
reset, reset, reset …
factory reset but just lighting solid magenta after lighting breathing cyane 1-2 sec. I did this more times. And a lot of resets.
tryed different power sourse and networks
read about solid magenta on other topics but didn’t worked with that troubleshooting
last try was to install the spark-cli without succes, I tought it will help to understand the problem.
