RAK5860 LEDs off

WisBlock

RAK5860 with RAK4631 and RAK19007, Arduino BSP.
Deep sleep seems to work but we’re unable to fully turn off BG77 LEDs.
Is there any solution for shutting down the power rail?

Hello @guczo

have you tried to turn off BG77 either via WIS_PWRKEY or via AT command? See here.

Thanks

Yes I tried, but apparently neither is actually shutting down BG77 completely.

Hello @guczo

aforementioned two options work for me to put BG77 into power-off mode and this also turns off both LEDs.

I don’t think cutting the power to the BG77 completely is possible as it is powered directly via VBAT.

Thanks
Felix

If nothing on these two methods as shared by felmue works, there might be a problem on the module.

If you are capable on checking the WIS_PWRKEY pin via oscilloscope, that will be best to confirm if the turn off signal really reached the chip.
