3.9.4. DPR Signal
EM06 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 EM06 module to provide an input
trigger which will reduce the output power in the radio transmission.
Table 15: Function of the DPR Signal
Please refer to document [2] for more details about AT+QCFG="sarcfg" command.
3.10. Tunable Antenna Control Interface*
ANTCTL[0:3] signals are used for tunable antenna control and should be routed to an appropriate
antenna control circuitry.
More details about the interface will be added in the future version of the document.
