Hello,
I am using nRF52832 and having a problem with the Low Power Mode. I am not sure if I am either not getting it to stay in low power mode when my UART is initialized, or if low power mode is using too much power.
When I do not even initialize the UART, my low power mode sees current usage in the 100s μA range
When I initialize my UART and then almost immediately uninitialize it, my sleep mode has a current draw of about 5-6mA. I have also disabled easy DMA to try to get the UART to use less power. Any ideas as to what is going on here? I have no other timers and am not connecting to it, so there should be no other events that wake it from this mode.
I have confirmed that the GPIOTE is not the issue in a separate isolated test. It seems to be something with the UART either causing a much higher current draw or not allowing the board to remain asleep
