#JDR - Jammed Detect & Report SELINT 0 / 1
<MNPL> - Maximum Noise Power Level
0..127
<DCMN> - Disturbed Channel Minimum Number
0..254
Note: issuing AT#JDR<CR> is the same as issuing the Read command.
Note: issuing AT#JDR=<CR> is the same as issuing the command
AT#JDR=0<CR>.
AT#JDR? Read command reports the current behaviour mode, Maximum Noise
Power Level and Disturbed Channel Minimum Number, in the format:
#JDR: <mode>,<MNPL>,<DCMN>
AT#JDR=? Test command reports the supported range of values for the parameters
<mode>,<MNPL> and <DCMN>
Example AT#JDR=2
OK
…jammer enters in the range…
#JDR: JAMMED
…jammer exits the range…
#JDR: OPERATIVE
Note It is suggested not to change the default setting for Maximum Noise Power
Level and Disturbed Channel Minimum Number.
If the device is installed in a particular environment where the default values
are not satisfactory the two parameters <MNPL> and <DCMN> permit to
adapt the detection to all conditions.
#JDR - Jammed Detect & Report
SELINT 2
AT#JDR=
[<mode>
[,<MNPL>,
<DCMN>]] Set command allows to control the Jammed Detect & Report feature.
The MODULE can detect if a communication Jammer is active in its range
and give indication to the user of this condition either on the serial line with
an unsolicited code or on a dedicated GPIO by rising it.
The MODULE can also report to the network the Jammed status condition,
even if normal communications are inhibited by the Jammer, by using a
unique message.
Parameters:
<mode> - behaviour mode of the Jammed Detect & Report
0 - disables Jammed Detect & Report (factory default)
1 - enables the Jammed Detect; the Jammed condition is reported on pin
GPIO2/JDR
GPIO2/JDR Low - Normal Operating Condition
