I am trying to do exactly what spirilis describes in the hypothetical remote sensing application on his wiki for the nrf24L01+ library:
"A typical application of the nRF24L01+ which takes full advantage of the MSP430's touted low-power modes is remote sensing with periodic wakeup involving an MSP430 circuit attached to sensors in a remote location. An MSP430 using either the VLO or LFXT1 driving ACLK to wake up the device periodically will switch on the nRF24, take sensor measurements and once the nRF24 is ready (5ms Standby-I wakeup time has elapsed), transmit those to a base station, fol
