Table 3‐03. PWM Chart
A non-zero value defines the time that the PWM output will be active with the RSSI value of the
last received RF packet. After the set time when no RF packets are received, the PWM output will
be set low (0 percent PWM) until another RF packet is received. The PWM output will also be set
low at power-up. A parameter value of 0xFF permanently enables the PWM output and it will
always reflect the value of the last received RF packet.
PWM output shares the Config input pin. When the module is powered, the Config pin will be an
input. During the power-up sequence, the Config pin will be read to determine whether the module
is going into AT Command Mode. After this, if RP parameter is a non-zero value, the Config pin will
be configured as an output and set low until the first RF packet is received. With a non-zero RP
parameter, the Config pin will be an input for RP ms after power up.

<Serial Interfacing> RO Command is used
to specify/read the time of
silence (no bytes received) after which
transmission begins. After a serial
byte is received and if no other byte is
received before the RO timeout,
the transmission will start.
<Diagnostics> RP Command is used to
enable a PWM (“Pulse Width Modulation”)
output on the Config pin which is
calibrated to show the level the
received RF signal is above the sensitivity
level of the module. The PWM
pulses vary from zero to 95 percent. Zero
percent means the received RF
signal is at or below the published
sensitivity level of the module. The
following
table shows levels above sensitivity and
PWM values.
The total period of the PWM output is
8.32 ms. There are 40 steps in the
PWM output and therefore the minimum
step size is 0.208 ms.
