Hi,
I'm using nRF52840 with two UARTs on SDK15.2.
I made some changes from the post below
https://devzone.nordicsemi.com/f/nordic-q-a/25173/nrf52840-uart1-not-working-in-sdk-14/99170#99170
My question is I couldn't bring down the sleep current, and I hunted down to the following lines of code:
ret_code_t ret = nrf_serial_init(&serial_uart, &m_uart0_drv_config, &serial_config); APP_ERROR_CHECK(ret); ret = nrf_serial_uninit(&serial_uart); APP_ERROR_CHECK(ret); __WFE();
After this, the current draw on nRF52840 is around 900 uA. I'm wondering how can I disable the UART completely to reduce the current draw.
Thanks,
