Function Documentation

void gzp_delay_rx_periods

(

uint16_t

rx_periods )

Delay function. Will add a delay equal to GZLL_RX_PERIOD * rx_periods [us].

Definition at line 794 of file gzp_device.c.

{
  uint16_t i;
  
  for(i=0; i < rx_periods; i++)
  {
    delay_us(GZLL_DEFAULT_PARAM_RX_PERIOD);
  }
}

static _Bool gzp_set_host_id

(

const uint8_t *

src )

Function for wriring variable holding "Host ID". Returns false if host ID could not be written.

Definition at line 544 of file gzp_device.c.

{
  memcpy(gzp_host_id, id, GZP_HOST_ID_LENGTH);
  return true;
}

_Bool gzp_get_host_id

(

uint8_t *

dst )

Function reading current "Host ID". On Host, returns false if host ID not yet generated.

Definition at line 550 of file gzp_device.c.

{
  memcpy(dst_id, gzp_host_id, GZP_HOST_ID_LENGTH);
  return true;
}
