Enable DW1000 "Smart Power" to increase range #14

Closed ataffanel closed 7 years ago

ataffanel commented 7 years ago

The "Smart Power" mode of the DW1000 UWB chip increases the transmit power with the assumption that the radio is not sending more than one packet per millisecond. Since we are not sending more than one packet per millisecond in any of our ranging algorithm we can enable this mode. We have verified that the smart-power mode allows us to get at least 3 times more range: https://wiki.bitcraze.io/misc:investigations:lps-max-range#results

The smart-power mode should be enabled by default in the node.
