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.
