dwm_uwb_cfg_get

Gets UWB configuration parameters.

void dwm_uwb_cfg_get(dwm_uwb_cfg_t *uwb_cfg)

Parameters

• input – (node)

• output – err_code, pg_delay, tx_power

• pg_delay – ? 1 byte ? (Transmitter Calibrati Pulse Generator Delay value)

• tx_power – ? 4 bytes ? (Units of transmission power control)

• pg_delay_comp – ? 1 byte ? (Transmitter Calibrati Pulse Generator Delay value, Compensated)

• tx_power_comp – ? 4 bytes ? (Units of transmission power control, Compensated)

C code example

dwm_uwb_cfg_t uwb_cfg;
dwm_uwb_cfg_get(&uwb_cfg);
printf("delay=%x, power=%lx compensated(%x,%lx)\n",
                     uwb_cfg.pg_delay,
                     uwb_cfg.tx_power,
                     uwb_cfg.compensated.pg_delay,
                     uwb_cfg.compensated.tx_power);
