at_ble_status_t at_ble_adv_channel_map_get ( at_ble_adv_channel_map_t ch)

get advertising channel.

Parameters
[in]chused advertising channels at_ble_adv_channel_map_t.
Returns
Upon successful completion the function shall return AT_BLE_SUCCESS, Otherwise the function shall return at_ble_status_t
at_ble_status_t at_ble_adv_channel_map_set ( at_ble_adv_channel_map_t  ch)

Set advertising channel using one of at_ble_adv_channel_map_t.

Note
Default value is AT_BLE_ADV_ALL_CHNLS_EN
Returns
Upon successful completion the function shall return AT_BLE_SUCCESS, Otherwise the function shall return at_ble_status_t
at_ble_status_t at_ble_adv_data_set ( uint8_t const *const  adv_data,
uint8_t  adv_data_len,
uint8_t const *const  scan_resp_data,
uint8_t  scan_response_data_len 
)

Set, clear or update advertisement and scan response data.

Note
  • To clear the advertisement data and set it to a 0-length packet, simply provide a valid pointer (pAdvData/pSrData) with its corresponding length (dlen/srdlen) set to 0.
  • The call will fail if pAdvData and pSrData are both NULL since this would have no effect.
Parameters
[in]adv_dataRaw data to be placed in advertisement packet. If NULL, no changes are made to the current advertisement packet data.
[in]adv_data_lenData length for adv_data. Max size 28 bytes, 3 bytes are reserved to set advertising AD type flags , shall not be set in advertising data.
[in]scan_resp_dataRaw data to be placed in scan response packet. If NULL, no changes are made to the current scan response packet data.
[in]scan_response_data_lenData length for scan_resp_data. Max size 31 bytes.
Note
The First three bytes in advertising data have been reserved in order to Fill Flags(0x01) AD type. This data is set according to advertising mode selected.
Returns
Upon successful completion the function shall return AT_BLE_SUCCESS, Otherwise the function shall return at_ble_status_t

at_ble_status_t at_ble_adv_data_update_on_the_fly ( at_ble_adv_data_update_on_the_fly_t update_on_the_fly_data)

Set, clear or update advertising data or scan response data or both on the fly (while an advertising operation is ongoing) .

Note
Parameters
[in]update_on_the_fly_dataupdate on the fly request parameters, refer to at_ble_adv_data_update_on_the_fly_t
Returns
Upon successful completion the function shall return AT_BLE_SUCCESS, Otherwise the function shall return at_ble_status_t

at_ble_addr_t peer_addr,
at_ble_filter_type_t  filtered,
uint16_t  interval,
uint16_t  timeout,
bool  disable_randomness 
)

Start advertising (GAP Discoverable, Connectable modes, Broadcast Procedure).

Parameters
[in]typeAdvertising type, see at_ble_adv_type_t for more info
[in]modeeither non-discoverable,General, Limited or Broadcaster , at_ble_adv_mode_t for more details
[in]peer_addrFor AT_BLE_ADV_TYPE_DIRECTED mode only, known peer address
[in]filteredpolicy at_ble_filter_type_t for more details
[in]intervalAdvertising interval between AT_BLE_ADV_INTERVAL_MIN and AT_BLE_ADV_INTERVAL_MAX in 0.625 ms units (20ms to 10.24s). This parameter must be set to 0 if type equals AT_BLE_ADV_TYPE_DIRECTED
[in]timeoutAdvertising time-out between 0x0001 and 0x028F in scale of Seconds, 0x0000 disables time-out. This parameter must be set to 0 if type equals AT_BLE_ADV_TYPE_DIRECTED.
Timeout only valid with AT_BLE_ADV_GEN_DISCOVERABLE and AT_BLE_ADV_LIM_DISCOVERABLE.
[in]disable_randomnessif True the device will advertise at the exact interval without adding the random 10msec
Precondition
If it is required to change BD address, at_ble_addr_set should be used otherwise default address will be used
Note
AT_BLE_ADV_REPORT will be received with error code in case of stack can not start advertising; refer to at_ble_status_t
