I could REALLY use help from someone.
I have been trying with little success.
In a nutshell: I want to Broadcast a Beacon from the Beacon app in the SDK and detect and read it in a break-pointed callback on a second BlueNRG-LP board.
I am not interested in any "Connection" type scenario with GATT / known addresses.. etc. I simply want to "detect" the Beacon that is being Broadcast by the one BlueNRG-LP board.
After the standard initializations (System and BLE SYS CLock, BLE Stack, UART, BSP IO power save ,....etc,) here is my code snippet for the "scanning" board:
uint8_t role = GAP_OBSERVER_ROLE | GAP_CENTRAL_ROLE;
uint8_t bdaddr[] = {BD_ADDR_MASTER};
uint8_t device_name[]={'N', 'o', 'd', 'e'};
uint8_t ret;
uint16_t service_handle, dev_name_char_handle, appearance_char_handle;
/* Configure Public address */
ret = aci_hal_write_config_data(CONFIG_DATA_PUBADDR_OFFSET, CONFIG_DATA_PUBADDR_LEN, bdaddr);
if(ret != BLE_STATUS_SUCCESS) {
PRINTF("aci_hal_write_config_data() failed: 0x%02x\r\n", ret);
return ret;
}
/* Set the TX power */
aci_hal_set_tx_power_level(0, OUTPUT_POWER_LEVEL);
/* GAP Init */
ret = aci_gap_init(role , 0, 0x07, 0x00, &service_handle, &dev_name_char_handle, &appearance_char_handle);
if(ret){
PRINTF("aci_gap_Init() failed: 0x%02x\r\n", ret);
return ret;
}
/* Set the device name */
ret = Gap_profile_set_dev_name(0, sizeof(device_name), device_name);
if(ret){
PRINTF("Gap_profile_set_dev_name() failed: 0x%02x\r\n", ret);
return ret;
}
ret = aci_gap_set_scan_configuration(DUPLICATE_FILTER_ENABLED, SCAN_ACCEPT_ALL, LE_1M_PHY_BIT, ACTIVE_SCAN, SCAN_INTERVAL, SCAN_WINDOW);
printf("Scan configuration for LE_1M_PHY: 0x%02X\n", ret);
//ret = aci_gap_set_scan_configuration(DUPLICATE_FILTER_ENABLED, SCAN_ACCEPT_ALL, LE_CODED_PHY_BIT, ACTIVE_SCAN, SCAN_INTERVAL, SCAN_WINDOW);
//printf("Scan configuration for LE_CODED_PHY: 0x%02X\n", ret);
ret = aci_gap_start_procedure(GAP_OBSERVATION_PROC /*GAP_GENERAL_DISCOVERY_PROC*/,LE_1M_PHY_BIT,0,0);
printf("GAP Start Procedure for LE_1M_PHY: 0x%02X\n", ret);
debounce_timer.callback = DebounceTimeoutCB;
scanningLEDTimerHandle.callback = ScanningLEDTimeoutCB;
writeTimerHandle.callback = writeTimeoutCB;
statsTimerHandle.callback = statsTimeoutCB;
return BLE_STATUS_SUCCESS;
.... and my callbacks:
void hci_le_extended_advertising_report_event(uint8_t Num_Reports,
Extended_Advertising_Report_t Extended_Advertising_Report[])
{
Extended_Advertising_Report_t * ptr = Extended_Advertising_Report;
return;
}
void hci_le_advertising_report_event(uint8_t Num_Reports,
Advertising_Report_t Advertising_Report[])
{
return;
}
I had also tried explicitly enabling the events through the event mask mechanism:
/* --- JRW Hopefully ticket out of purgatory */
ret = hci_le_set_event_mask(LE_Event_Mask);
if(ret)
{
PRINTF("hci_le_set_event_mask 0x%02X\n",ret);
}
where event mask:
static uint8_t LE_Event_Mask[8]={
HCI_LE_EVT_MASK_BYTE0_ADVERTISING_REPORT ,
HCI_LE_EVT_MASK_BYTE1_EXTENDED_ADVERTISING_REPORT | HCI_LE_EVT_MASK_BYTE1_PHY_UPDATE_COMPLETE,
0x00,
0x00,
0x00,
0x00};
I cannot get the callbacks to fire for BlueNRG-LP (running the stock ST Micro SDK Beacon Demo)
Any suggestions? I just need a hint (other than give up) not the answer...
