Wake_On_Wan; Dpr - Quectel EM160R-GL Hardware Design

3.8.4. WAKE_ON_WAN#

The WAKE_ON_WAN# is an open drain pin, which requires a pull-up resistor on the host. When a URC
returns, a one-second low level pulse signal will be outputted to wake up the host. The module operation
status indicated by WAKE_ON_WAN# is shown as below.

Output a one-second pulse signal at low level
Always at high level
Host
NOTE: The voltage level on VCC_IO_HOST depends on the host side due to open drain in pin 23.

3.8.5. DPR

EM160R-GL 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.
