dwm_usr_data_read
Reads user data from the node. The new data received on UWB causes the setting of a dedicated flag in the status (see dwm_status_get) and causes the generation of an event in the user applications (see dwm_evt_listener_register).
-
void dwm_usr_data_read(uint8_t*, uint8_t*)
- Parameters
input – (none)
output – Status code, data, len
data – 1-34 bytes (the user data)
len – 1 byte (length of the data)
C code example
uint8_t data[DWM_USR_DATA_LEN_MAX];
uint8_t len;
len = DWM_USR_DATA_LEN_MAX;
dwm_usr_data_read(data, &len);
