Most likely transmitting data requires more current. Your power supply is incapable of providing the additional current therefore the voltage dips and triggers the warning. Get a better power supply.hi everyone,
i was working with sim7000e hat to send some data using cellular network, so i had to dial-up networking using PPP
when i enter sudo pppd call gprs, the low voltage warning apperas
the hat can be connected to the pi via uart or usb, in both i get the warning, the power supply is not the official one, but it's been a while using it with no problems (camera with ir leds, mouse, keyboard, running object detection model...)
& thanks
