Date: Fri, 20 Mar 2015 12:52:20 +0530 [thread overview]
Message-ID: <1426836141-21528-3-git-send-email-varkab@cdac.in> (raw)

This patch fix the updated register settings for transmit power.
As per the datasheet [section 28.1 Register Settings Update]

from the default value.
CC2520_TXPOWER_4 indicates the value 0x32 (0 dBm).
