AT commands
Parameter range
0 - 0xFFFF
Default
0
DB (Last Packet RSSI)
Reports the RSSI in -dBm of the last received RF data packet. DB returns a hexadecimal value for the -
dBm measurement.
For example, if DB returns 0x60, then the RSSI of the last packet received was -96 dBm.
The RSSI measurement is accurate from approximately -50 to -100 dBm.
DB only indicates the signal strength of the last hop. It does not provide an accurate quality
measurement for a multihop link.
If the XTC RF Module has been reset and has not yet received a packet, DB reports 0.
This value is volatile (the value does not persist in the device's memory after a power-up sequence).
Parameter range
0x28 - 0x6E (-40 dBm to -110 dBm) [read-only]
Default
0
EA (MAC ACK Failure Count)
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
0
N/A
ER (Receive Count Error)
This count increments when a device receives a packet that contains integrity errors of some sort.
When the number reaches 0xFFFF, the firmware does not count further events.
To reset the counter to any 16-bit 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).
Occasionally random noise can cause this value to increment.
The ER parameter is not reset by pin, serial port or cyclic sleep modes.
