#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: <status>
where:
<status>
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 <mode>=1 and <mode>=2.

4 - enables the Jammed Detect; the Jammed condition is reported with an

unsolicited code every 3s on serial line, in the format:


#JDR: <status>
where:
<status>
JAMMED - Jammed condition detected
OPERATIVE - Normal Operating condition restored. This code will be

shown only after a jammed condition has occurred.

5 - enables the Jammed Detect; the MODULE will make both the actions

as for <mode>=1 and <mode>=4.

<MNPL> - Maximum Noise Power Level
0..127
<DCMN> - 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: <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.
