void dwm_usr_data_write(uint8_t*, uint8_t, boolean_t)

Parameters

• input – data, len, overwrite

• data – ? 34 bytes max ? (the user data to be written)

• len – (data length, 34 bytes max)

• overwrite – ? bool ? (forced write, will overwrite data that are not yet sent to the bridge)

• output – Status code

C code example

uint8_t len, data[DWM_USR_DATA_LEN_MAX];
len = DWM_USR_DATA_LEN_MAX;
dwm_usr_data_write(data, len, false);

SPI/UART example
