The RSSI value increases with increased input signal strength in 0.5 dB steps. Input signal strength is
given by (typ):
P = - RSSI / 2 [dBm]
The dynamic range of the RSSI (P) goes from the Sensitivity level up to typical -30 dBm (RSSI
saturation level).
Temperature Reading (U- Command)
The module provides readings of a digital temperature-monitoring sensor (TEMP) through the ‘U’
command. The module returns an 8 bit character (one byte) indicating the current temperature in
degrees Celsius (°C) followed immediately by a second character which is the prompt (‘>’).
The TEMP value is also returned in all
GENERAL EVENT PACKET FORMAT
packets while the module is
operating in Packet mode
The TEMP value increases with increased temperature in 1 °C steps and accuracy of +/- 2 °C.
Temperature is given by:
T = TEMP(dec) - 128 [°C] (
Example
: TEMP=0x98 24 °C)
Power Supply Voltage Reading (V- Command)
The module provides readings of an internal power supply voltage-monitoring sensor (VCC) through the
‘V’ command. The module returns an 8 bit character (single byte) indicating the current power supply
voltage level, followed immediately by a second character which is the prompt (‘>’). The command can
be useful for battery voltage level monitoring.
The VCC value is also returned in all
GENERAL EVENT PACKET FORMAT
packets while the module is
operating in Packet mode
The VCC value increases with increased power supply voltage in 30 mV steps. The power supply
voltage is given by:
V = VCC(dec)*0.030 [V] (
Example
: VCC=0x68 equals 3.12 [V])
Set Configuration Memory (M- Command)
Configuration parameters in non-volatile
