Hey Folks,
The new LPUART (doc here https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.0/nrf/drivers/uart_nrf_sw_lpuart.html) is supposed to address the issue of the UART consuming a few hundred microamps. It requires two additional control lines: REQ and RDY.
The custom board I'm building firmware for does not have these additional control lines. But all I need to do is issue a fire and forget command using the UART (or LPUART) and not worry about a response.
Given that two-way comms is not required, can the LPUART be used without the 2 control lines? If not, is another valid approach to just continue using the standard UART driver and shut down the peripheral directly without Zephyr's involvement?
Regards,
Kiran
