<mode>
0 should inquire status by reading command;
1 only report jamming status via URC from serial port;
2 only report jamming status via the PIN;
3 report jamming status via URC as well as the PIN.
<var>
1-255 255 is default value
The threshold to separate "+SJDR: JAMMING DETECTED"
from "+SJDR: INTERFERENCE DETECTED" (while the signal
strength variance is higher than <var>, there could be
industrial
DETECTED" is reported).
<display>
1 report jamming status via URC when jamming status
changed.(only when <mode> is set to "1" or "3")
0 report jamming status via URC every 3000ms. (only when
<mode> is set to "1" or "3")
Note:
When you query jamming detection status after enable jamming
detection mode, you will get the URC of the format below:
+SJDR:1,<mode>,<var>,<display>,<result>
<result>=0, means no jamming.
<result>=1, means jamming is detected.
<result>=2, means industrial interference is detected.
"+SJDR: INTERFERENCE DETECTED" indicates industrial interference
which signifies unintentional radio link disturbances by strong
industrial radio sources.G
