Diagnostics
M1
(v1.xA0*)
I/O Settings
{I/O Line
Passing}
PWM1 Output Level. Set/Read the PWM1
output level.
0 - 0x03FF -
PT
(v1.xA0*)
I/O Settings
{I/O Line
Passing}
PWM Output Timeout. Set/Read output
timeout value for both PWM outputs. When
PWM is set to a non-zero value: Due to I/O line
passing, a time is started which when expired
will set the PWM output to zero. The timer is
reset when a valid I/O packet is received.]
0 - 0xFF [x 100 ms] 0xFF
RP I/O Settings
{I/O Line
Passing}
RSSI PWM Timer. Set/Read PWM timer register.
Set the duration of PWM signal output on the
RSSI pin. The signal duty cycle is updated with
each received packet and is shut off when the
timer expires.]
0 - 0xFF [x 100 ms] 0x28
(40d)
* Firmware version in which the command was first introduced (firmware versions are numbered in
hexadecimal notation.)

VR Diagnostics Firmware Version. Read firmware version of the RF
module.
0 - 0xFFFF
[read-only]
Factory
-set
VL
(v1.x80*)
Diagnostics Firmware Version - Verbose. Read detailed version
information (including application build date, MAC,
PHY and bootloader versions). The VL command has
been deprecated in version 10C9. It is not supported
in firmware versions after 10C8
--
HV
(v1.x80*)
Diagnostics Hardware Version. Read hardware version of the RF
module.
0 - 0xFFFF
[read-only]
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.
0x17-0x5C (XBee)
0x24-0x64 (XBee-
PRO)
[read-only]
-
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.
