Hello,
I have a use case where I need to use UART_RTS and UART_CTS as GPIO for toggling the led. I also want to use the other two pins UART_TX and UART_RX for handling UART specific function at the same time. I made an overlay file for this. It works when I flashed it on nRF9160dk but in Fanstel BLG840F, it doesn't seem to work at all.
I am certain it is due to the overlay being incorrect for the custom board - Fanstel BLG840F. But not sure how to rectify it!
I also went through driving a GPIO pin directly but it didn't even worked on nRF9160dk board.
Hoping some help from the community.
