Digi XBee SX 868 - RR (Unicast Mac Retries); ED (Energy Detect)

AT commands MAC/PHY commands
XBee® SX 868 RF Module User Guide
116
Sets or displays the power level at which the device transmits conducted power. Power levels are
approximate.
Parameter range
0 - 4
Setting Power level*
0 2 mW EIRP
1 5 mW EIRP
2 10 mW EIRP
3 16 mW EIRP
4 32 mW EIRP
* EIRP stands for Effective Isotropically Radiated Power, which is the device's output power plus 2.1
dBi (dipole antenna gain).
Default
4
RR (Unicast Mac Retries)
This command applies to the XBee SX 868 RF Module.
Set or read the maximum number of MAC level packet delivery attempts for unicasts. If RR is non-
zero, the sent unicast packets request an acknowledgment from the recipient. Unicast packets can be
retransmitted up to RR times if the transmitting device does not receive a successful
acknowledgment.
Parameter range
0 - 0xF
Default
0x0A (decimal 10)
ED (Energy Detect)
This command applies to the XBee SX 868 RF Module.
Starts an energy detect scan. This command accepts an argument to specify the time in milliseconds
to scan all channels. The device loops through all the available channels until the time elapses. It
returns the maximal energy on each channel, a comma follows each value, and the list ends with a
carriage return. The values returned reflect the energy level that ED detects in -dBm units.
Parameter range
0 - 0xFF
Default
0x10
