VR Diagnostics
Firmware Version. Read firmware
version of the RF module. 0 - 0xFFFF

Factory-set
VL (v1.x80*) Diagnostics
Firmware Version - Verbose.
Read detailed version information
(including application build date,
MAC, PHY and bootloader
versions).

HV (v1.x80*) Diagnostics
Hardware Version. Read
hardware version of the RF
module.

Factory-set
DB Diagnostics
Received Signal Strength. Read
signal level [in dB] of last good
packet received (RSSI). Absolute
value is reported. (For example:
0x58 = -88 dBm) Reported value is
accurate between -40 dBm and RX
sensitivity.

EC (v1.x80*) Diagnostics
CCA Failures.Reset/Read count of
CCA (Clear Channel Assessment)
failures. This parameter value
increments when the module does
not transmit a packet because it
detected energy above the CCA
threshold level set with CA
command. This count saturates at
its maximum value. Set count to “0”
to reset count.
0 - 0xFFFF -
EA (v1.x80*) Diagnostics
ACK Failures. Reset/Read count
of acknowledgment failures. This
parameter value increments when
the module expires its transmission
retries without receiving an ACK on
a packet transmission. This count
saturates at its maximum value.
Set the parameter to “0” to reset
count.
0 - 0xFFFF -
ED (v1.x80*) Diagnostics
Energy Scan. Send ‘Energy
Detect Scan’. ED parameter
determines the length of scan on
each channel. The maximal energy
on each channel is returned and
each value is followed by a
carriage return. Values returned
represent detected energy levels in
units of -dBm. Actual scan time on
each channel is measured as Time
= [(2 ^ SD) * 15.36] ms. Total scan
time is this time multiplied by the
number of channels to be scanned.
