Hello,
we are testing the LPUART example in loopback with a very simple circuit. The carrier module is PAN1780 - nrf52840 on a custom board with no other things connected. Please refer to the following schematic.
The example is this github.com/.../lpuart
We are unable to verify low power consumption. The power consumption floor is 1.1mA without any debugger connected ar any other wiring/peripheral.
However, if we disable reception (comment "err = uart_rx_enable(lpuart, buf, BUF_SIZE, 10000);") the current drops to 20uA.
SDK version is 2.6.1
Can you help us?
Thanks,
Marco
