Hi Nordic Team,
I am using the nRF52840 microcontroller and have interfaced a modem with one of its UART modules, as my modem communicates with the Nordic chip via UART. The issue I am facing is that even when I completely turn the modem OFF, the UART is still consuming approximately 150 to 200 µA. Specifically, the line CONFIG_SERIAL=y
is causing this power consumption. If I disable this line in my proj.conf
file, I encounter compilation errors because I am using UART drivers in my project.
Is there a solution to this problem so that the UART only consumes power when the modem is in use? Below are some configurations I am using in my project. Kindly be noted that I have only TX and RX lines of UART.
