Wlan

Send HCI_CMND_SIMPLE_LINK_START to CC3000.

Parameters:

usPatchesAvailableAtHost

flag to indicate if patches available from host or from EEPROM. Due to the fact the patches are burn to the EEPROM using the patch programmer utility, the patches will be available from the EEPROM and not from the host.

Returns:

none

Add profile.

When auto start is enabled, the device connects to
station from the profiles table. Up to 7 profiles are supported.
If several profiles configured the device choose the highest
priority profile, within each priority group, device will choose
profile based on security policy, signal strength, etc
parameters. All the profiles are stored in CC3000 NVMEM.

Parameters:

ulSecType	WLAN_SEC_UNSEC,WLAN_SEC_WEP,WLAN_SEC_WPA,WLAN_SEC_WPA2
ucSsid	ssid SSID up to 32 bytes
ulSsidLen	ssid length
ucBssid	bssid 6 bytes
ulPriority	ulPriority profile priority. Lowest priority:0.
ulPairwiseCipher_Or_TxKeyLen	key length for WEP security
ulGroupCipher_TxKeyIndex	key index
ulKeyMgmt	KEY management
ucPf_OrKey	security key
ulPassPhraseLen	security key length for WPA

Returns:

On success, zero is returned. On error, -1 is returned

Connect to AP.

Parameters:

sec_type	security options: WLAN_SEC_UNSEC, WLAN_SEC_WEP (ASCII support only), WLAN_SEC_WPA or WLAN_SEC_WPA2
ssid	up to 32 bytes and is ASCII SSID of the AP
ssid_len	length of the SSID
bssid	6 bytes specified the AP bssid
key	up to 16 bytes specified the AP security key
key_len	key length

Returns:

On success, zero is returned. On error, negative is returned.
Note that even though a zero is returned on success to trigger
connection operation, it does not mean that CCC3000 is already
connected. An asynchronous "Connected" event is generated when
actual association process finishes and CC3000 is connected to
the AP. If DHCP is set, An asynchronous "DHCP" event is
generated when DHCP process is finish.

Warning:

Please Note that when connection to AP configured with security
type WEP, please confirm that the key is set as ASCII and not as HEX.

Get entry from scan result table.

The scan results are returned one by one, and each entry represents a single AP found in the area.
The following is a format of the scan result:

• 4 Bytes: number of networks found
  
• 4 Bytes: The status of the scan: 0 - aged results, 1 - results valid, 2 - no results
  
• 42 bytes: Result entry, where the bytes are arranged as follows:
  
  • 1 bit isValid - is result valid or not
    
  • 7 bits rssi - RSSI value
    
  • 2 bits securityMode - security mode of the AP: 0 - Open, 1 - WEP, 2 WPA, 3 WPA2
    
  • 6 bits SSID name length
    
  • 2 bytes the time at which the entry has entered into scans result table
    
  • 32 bytes SSID name
    
  • 6 bytes BSSID
    

    Parameters:

    [in]	scan_timeout	parameter not supported
    [out]	ucResults	scan result (_wlan_full_scan_results_args_t)

    Returns:

    On success, zero is returned. On error, -1 is returned scan_timeout, is not supported on this version.

Set connection policy.

When auto is enabled, the device tries to connect according the following policy:
1) If fast connect is enabled and last connection is valid,
the device will try to connect to it without the scanning
procedure (fast). The last connection will be marked as
invalid, due to adding/removing profile.
2) If profile exists, the device will try to connect it
(Up to seven profiles).
3) If fast and profiles are not found, and open mode is
enabled, the device will try to connect to any AP.
Note that the policy settings are stored in the CC3000 NVMEM.

Parameters:

should_connect_to_open_ap	enable(1), disable(0) connect to any available AP. This parameter corresponds to the configuration of item # 3 in the brief description.
should_use_fast_connect	enable(1), disable(0). if enabled, tries to connect to the last connected AP. This parameter corresponds to the configuration of item # 1 in the brief description.
auto_start	enable(1), disable(0) auto connect after reset and periodically reconnect if needed. This configuration configures option 2 in the above description.

Returns:

On success, zero is returned.
On error, -1 is returned
