<CR>
A carriage return <CR> is sent at
the end of the AS command. The
Active Scan is capable of
returning up to 5 PanDescriptors
in a scan. The actual scan time
on each channel is measured as
Time = [(2 ^SD PARAM) * 15.36]
ms. Note the total scan time is
this time multiplied by the number
of channels to be scanned. Also
refer to SD command description.
Energy Scan. Send an Energy
Detect Scan. This parameter
determines the length of scan on
each channel. The maximal
energy on each channel is
returned & each value is followed
by a carriage return. An additional
carriage return is sent at the end
of the command. The values
returned represent the detected
energy level in units of -dBm. The
actual scan time on each channel
is measured as Time = [(2 ^ED) *
15.36] ms. Note the total scan
time is this time multiplied by the
number of channels to be
scanned (refer to SD parameter).
AES Encryption Enable.
Disable/Enable 128-bit AES
encryption support. Use in
conjunction with the KY
command.
AES Encryption Key. Set the
128-bit AES (Advanced
Encryption Standard) key for
encrypting/decrypting data. The
KY register cannot be read.
*Firmware version in which the command was first introduced (firmware versions are
numbered in hexadecimal notation.)
Commands-RF Interfacing
Power Level. Select/Read the
power level at which the RF
module transmits conducted
power.
0 - 4
0 = -10 / 10 dBm
1 = -6 / 12 dBm
2 = -4 / 14 dBm
3 = -2 / 16 dBm
4 = 0 / 18 dBm
CCA Threshold. Set/read the
CCA (Clear Channel
Assessment) threshold. Prior to
transmitting a packet, a CCA is
