#JDR - Jammed Detect & Report SELINT 2
GPIO2/JDR High - Jammed Condition.
2 - enables the Jammed Detect; the Jammed condition is reported with a
single unsolicited result code on serial line, in the format:
#JDR:
where:
JAMMED - Jammed condition detected
OPERATIVE - Normal Operating condition restored. This code will be
shown only after a jammed condition has occurred.
3 - enables the Jammed Detect; the MODULE will make both the actions
as for =1 and =2.
4 - enables the Jammed Detect; the Jammed condition is reported with an

- Maximum Noise Power Level
0..127
- Disturbed Channel Minimum Number
0..254
AT#JDR? Read command reports the current behaviour mode, Maximum Noise
Power Level and Disturbed Channel Minimum Number, in the format:
#JDR: ,,
AT#JDR=? Test command reports the supported range of values for the parameters
, and
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 and permit to
adapt the detection to all conditions.
