3.10.4. DPR Signal 
The module provides a DPR (Dynamic Power Reduction) signal for body SAR (Specific Absorption Rate) 
detection. The signal is sent by a host system proximity sensor to the module to provide an input trigger 
which will reduce the output power in the radio transmission.

Please refer to document [2] for more details about AT+QCFG="sarcfg" command. 
 
3.11.  Antenna Tuner Control Interface* 
 
ANTCTL [0:3] signals are used for antenna tuner control and should be routed to an appropriate antenna 
control circuitry.   
 
More details about the interface will be added in the future version(s) of the document.
