Atmega128RFA1 Zigduino random number for unique eui64 Why not use the Atmel-derived function radio_get_trx_state and radio_set_trx_state, which includes the appropriate delay_us for the state transitions?
Google will find them...

Atmega128RFA1 Zigduino random number for unique eui64
The two random bits from PHY_RSSI worked with my 128RFA1. Don't know what that struct is, are you extracting the correct bits? What does full register contain?...
ATmega128rfa1 sleep&wake up with timers Contiki has both interrupt and non-interrupt sleep in the AVR code base for the Raven, and maybe for the 128RFA1 But it may not have been included in what you are looking at...

4.2V on 5V power regulator I suspect the question is, can you charge a 4.2 volt battery from regulated 5 volts. If it's a lithium battery that can cause a fire at any future time in the life of the cell....

Problem with clock accuracy. You can phase lock a high frequency CPU clock to the 32kHz crystal. Run a timer off the CPU clock, interrupt every millisecond off the crystal or so and adjust OSCCAL based on the...
