Dpr; Status; Cellular/Wlan Coex Interface - Quectel 5G Module Series Hardware Design

4.5.5. DPR*

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

NOTE
See document [3] for more details about AT+QCFG="sarcfg" command.

4.5.6. STATUS*

The module provides two status indication pins for communication with IPQ807x device. Pin 38
(SDX2AP_STATUS) outputs the status indication signal to IPQ807x device, and pin 68
(AP2SDX_STATUS) inputs the status indication signal from IPQ807x device. For more details, see
document [4].

4.6. Cellular/WLAN COEX Interface*

The module provides the cellular/WLAN COEX interface, the following table shows the pin definition of
this interface.
