AT commands
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
N/A
Default
N/A

EA command

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

EC (CCA Failures)

Sets or displays the number of frames that were blocked and not sent due to CCA failures or
receptions in progress. If CCA is disabled (CA is 0), then this count only increments for frames that are
blocked due to receive in progress. When this count reaches its maximum value of 0xFFFF, it stops
counting.
You can reset EC to 0 (or any other value) at any time to make it easier to track errors. 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

Sleep settings commands

SM command

By default, Sleep Modes are disabled (SM = 0) and the device remains in Idle/Receive mode. When in
this state, the device is constantly ready to respond to either serial or RF activity.
When operating in Pin Sleep (SM = 1),
device to sleep.
