I'm using a CC2540 as the BTLE component for a wireless multimeter. The meter has a button to initialize the BTLE device and begin advertising / broadcasting. I'm wondering if it would be wiser to use the comparator to bring the CC2540 out of sleep mode 3, or use the Reset_N to insure that the CC2540 initializes in the most stable configuration.
The BTLE module will have a continuous supply of power (i.e. power to the CC2540 will not be turned off even when the selector switch is turned off).
Thoughts / suggestions?
