pls8x RemoteWakeUp/Event/USB | Thales IoT Developer Community

December 19, 2019 - 8:59pm, 1712 views

Hello everyone !

I'm trying to use  the remote wake up.

What I'm trying to do is to send a signal on GPIO1 when the ****m receive data and then wake the computer using the GPIO1 

The GPIO1 is connected to a computer and is configured as key input in linux.  

Using  "AT^SCFG="RemoteWakeUp/Event/URC" GPIO1 " I can validate that the gpio1 is correctly setup and does wakeup the computer on a URC event.

So I tried to configure the ****m using USB as well with:  "AT^SCFG="RemoteWakeUp/Event/USB", GPIO1" and "AT^SCFG=\"RemoteWakeUp/Ports\", rmnet0" 

But this does nothing. 

My expectation is that when there is usb data available for the TE (the computer) is should send a signal to GPIO1. Am I correct ? 

The pls8x doc say the following : "Configure line that shall be toggled to wake up the TE when a Remote Wakeup Event occurs on USB."

So when does a Remote Wakeup Event occurs on USB ? 


Is there an other way to send a signal on GPIO1 ? We use the ****m in WWAN ****  (the cdc-eth driver in linux) when we receive data ?  

What we want is to let the computer sleep all the time except when we receive data.

Thank you ! 

this is the current output of AT^SCGF? (I remove the cfg for URC in this one)
