Hi
We using the CC1110 in our product and recently facing some similar symptoms of difficulty of wake-up after power up and problems to switch from RC to HS Osc.
what really interesting is that when the device is power-up at 3.3V or with the SmartRF04EB everything OK, but if it power up at 3.6V as design most of the time it's stuck...
Do have any idea?
Thank you!
