AT commands
%V (Voltage Supply Monitoring)
Reads the voltage on the Vcc pin in mV.
Parameter range
0 - 0xFFFF (in mV) [read only]
Default
N/A
EA (MAC ACK Failure Count)
The number of unicast transmissions that time out awaiting a MAC ACK. This can be up to RR +1
timeouts per unicast when RR > 0.
This count increments whenever a MAC ACK timeout occurs on a MAC-level unicast. When the number
reaches 0xFFFF, the firmware does not count further events.
To reset the counter to any 16-bit unsigned value, append a hexadecimal parameter to the command.
This value is volatile (the value does not persist in the device's memory after a power-up sequence).
Parameter range
0 - 0xFFFF
Default
0x0
TP (Temperature)
The current module temperature in degrees Celsius. The temperature is represented in two's
complement, as shown in the following example:
1 °C = 0x0001 and -1°C = 0xFFFF
Parameter range
0 - 0xFFFF (Celsius) [read-only]
Default
N/A
CK (Configuration Checksum)
Reads the cyclic redundancy check (CRC) of the current AT command configuration settings to
determine if the configuration has changed.
After a firmware update this command may return a different value.
Parameter range
0 - 0xFFFF [read-only]
Default
N/A
Digi XBee® 3 Zigbee® RF Module
Diagnostic commands
