On GAP Central, HCI_Event_CB() callback (EVT_VENDOR as main event), the
EVT_BLUE_GATT_NOTIFICATION
is raised on reception of the characteristic notification
(acceleration or free fall) from the GAP Peripheral device. Follow a pseudo code of the
HCI_Event_CB()
callback:
void HCI_Event_CB(void *pckt)
{
hci_uart_pckt *hci_pckt = pckt;
hci_event_pckt *event_pckt = (hci_event_pckt*)hci_pckt->data;
if(hci_pckt->type != HCI_EVENT_PKT return;
switch(event_pckt->evt){
case EVT_VENDOR:
{
/* Get the vendor event data */
evt_blue_aci *blue_evt = (void*)event_pckt->data;
switch(blue_evt->ecode)
{
case EVT_BLUE_GATT_NOTIFICATION:
