EA
(v1.x80*)
Diagnostics ACK Failures. Reset/Read count of acknowledgment
failures. This parameter value increments when the
module expires its transmission retries without
receiving an ACK on a packet transmission. This count
saturates at its maximum value. Set the parameter to
“0” to reset count.
0 - 0xFFFF -
ED
(v1.x80*)
Diagnostics Energy Scan. Send ‘Energy Detect Scan’. ED
parameter determines the length of scan on each
channel. The maximal energy on each channel is
returned and each value is followed by a carriage
return. Values returned represent detected energy
levels in units of -dBm. Actual scan time on each
channel is measured as Time = [(2 ^ SD) * 15.36] ms.
Total scan time is this time multiplied by the number
of channels to be scanned.
0 - 6 -
* Firmware version in which the command was first introduced (firmware versions are numbered in
hexadecimal notation.)
