PL8S-X : RING0 toggle during PPP session for incoming data | Thales IoT Developer Community

I would like to know if it's possible to have the RING0 pin toggle on incoming data, when the ****m is in a PPP session. The ****m is connected to the main CPU through USB and we have RING0 and the GPIO1 lines connected to two CPU GPIO pins. There is no problem making the ****m work with pppd and communicating with remote servers. Our board ***** to sleep as much as possible, so the application wakes up from time to time and pings the backend. The backend has a very small window to send messages to the module. It works great.

Now, the "management" want to be able to send data any time to the module. But we really need to sleep as much as possible. What better project for our new employee ;-)

He tried to play with every values on ^SCFG related to the RING0 or wakeup, validated that the GPIOs are set and tried various combinaisons of other parameters to make it work.  Sadly, without success.

I was wondering if the RING0 toggled by URC would only work in "normal" direct AT command interface, where the packet are exchanged with ^SISW and ^SISR. Is it possible to have notification of data reception while in PPP ****?

Thanks
