Wake-Up Status of Teseo-LIV3F

[Stefano Francavilla]

Hi guys, i'm working with the GNSS expansion board X-NUCLEO-GNSS1A1, plugged to STM32F411RE Nucleo board. I looked inside the X-Cube GNSS1 expansion software package, which provides also some ready-to-be-built examples. I've chosen the simpler one, "GetPos", and after building and running a serial terminal, i see from the menu that the "wakeupstatus" is always "0". I've tried to add some code that set the wakeup pin, but nothing changes.

I've used the following configuration of the jumper:

J2 open

J3 closed

J4 closed

J5 open

J6 closed

J7 open

J8 open

J9 closed

J10 open

J11 open

J12 open

J13 closed

J14 closed

J15 closed

Any suggestions?

Ciao Stefano

Wakeup signal can be routed on:

• J7 open (D4)
• J9 closed (13)

in your case J9 is ok.

In the Tese-LIV3F the wakeup signal (pin-5) is an Input-signal used to wakeup the module from Standby.

If you see the led D2, (the Red led) blinking, this means the module is already running and this could explain why the Wake-Up signal is doing nothing.

To test the wakeup you should move the module in standby (for example you can use the NMEA command: "$PSTMFORCESTANDBY,00010" which forces the module to sleep 10 seconds) and while the module is sleeping you can wakeup the module toggling the wakeup-pin.

Hope this helps.

Regards

Francesco

​Ciao Francesco and Stefano,

In the Jumper configuration, J11 (SCL) and J12 (SDA) has to be closed.
