I met a problem here and hop anyone can help. Thanks.
I enable hardware control in menuconfig, build a firmware of hci_uart sample and burn the firmware into nrf52_pca10040 (nrf52832),
and then connect it with my NXP board via uart， tx rx rts cts,(top menu) → Device Drivers → Serial Drivers → nRF UART nrfx driversZephyr Kernel Configuration[*] UART Port 0 Driver type (nRF UART 0) --->[*] Enable interrupt support on port 0[ ] Enable parity bit[*] Enable flow control
but when I attach the ble with command hciattach, it prints time out and seems the uart cannot communicate.
So I wonder if the hardware flow control works fine with nrf52832 or zephyr ? Or maybe my way to enable hardware flow control is wrong ?
By the way, is there any problems that we use software flow control instead of hardware flow control when the baudrate of uart is 1M ?
Thanks if someone can give me any advice.
