Can the uart data transfer format have no stop bits? How to change it?

[strengthstrong]

8-bit data, no stop bits,
No stop position, that is, transmission of 8 bits, 8 bits are data, nordic can do it, I found a place where the city did not find the stop position for a long time.

Hi,

The nRF52832 always use one stop bit, and this is the default behavior for all nRF5 devices. The nRF52810 and nRF52840 also support 2 stop bits, configurable by the STOP field in the CONFIG register for the UARTE peripheral. It is not possible to disable stop bit altogether (no stop bits).

thank you

Hi

I am wondering how to reach CONFIG register through SDK. I need 2 stop bits and I have found definitions in nrf52840_bitfields.h but how to apply this? I have read that 2 stop bit is not supported. Is it still the case? I am using SDK 15.3.0

May be, after "nrf_serial_init()"?

...
nrf_serial_init (&_your_serial_uarte, &_your_uarte_drv_config, &_your_serial_config);
_your_serial_uarte.instance.uarte.p_reg->CONFIG |= (uint32_t) (UARTE_CONFIG_STOP_Two << UARTE_CONFIG_STOP_Pos);
