Function Documentation
◆ gos_network_get_mac()
gos_result_t gos_network_get_mac | ( | gos_interface_t |
interface,
|
char * |
mac_str_buffer
|
||
) |
Get string representation of module's MAC address.
- Note
- Supplied buffer but be at least 18 characters,
- Parameters
-
[in] interface
Network interface to get MAC address [out] mac_str_buffer
Buffer to hold Wi-Fi MAC address in string format
- Returns
- gos_result_t result of api call
◆ gos_network_get_rssi()
gos_result_t gos_network_get_rssi | ( | int32_t * |
rssi_ptr
|
) |
Get the Received Signal Strength Indicator (RSSI) of the WLAN interface.
The returns the RSSI of the WLAN interface IF the interface it currently up, (i.e. if gos_network_is_up() returns true for GOS_INTERFACE_WLAN ). IF the interface is not up then this returns a result of GOS_NOTUP and the RSSI value is -999.
If RSSI averaging is enabled then the averaged RSSI is returned. If RSSI averaging is disabled then the raw RSSI is returned.
For more info about RSSI averaging, see Gecko OS Varaible API documentation wlan.rssi_average .
- Parameters
-
[out] rssi_ptr
Pointer to hold RSSI value
- Returns
- gos_result_t result of api call
◆ gos_network_lookup()
gos_result_t gos_network_lookup | ( | gos_interface_t |
interface,
|
const char * |
hostname,
|
||
gos_ip_address_t * |
ip_address,
|
||
uint32_t |
timeout_ms
|
||
) |
Resolve hostname into corresponding IP address.
See Gecko OS Command API documentation: network_lookup .
- Note
- This will try up to 10 seconds to resolve the given hostname
- Parameters
-
[in] interface
Network interface to do lookup [in] hostname
Domain name to resulve [out] ip_address
corresponding IP address of given hostname [in] timeout_ms
Maximum time in milliseconds to try to resolve domain
- Returns
- gos_result_t result of api call
◆ gos_network_ping()
gos_result_t gos_network_ping | ( | gos_interface_t |
interface,
|
const char * |
hostname,
|
||
uint32_t * |
reply_time_ms
|
||
) |
Ping specified host and return reply time.
See Gecko OS Command API documentation: ping .
- Parameters
-
[in] interface
gos_interface_t network interface to issue ping [in] hostname
domain name or IP address to issue ping [out] reply_time_ms
time in milliseconds for ping reply
- Returns
- gos_result_t result of api call
◆ gos_network_scan()
gos_result_t gos_network_scan | ( | gos_scan_result_t ** |
result_list,
|
uint16_t |
channel_mask,
|
||
const gos_ssid_t * |
ssid
|
||
) |
Scan for Wi-Fi networks.
See Gecko OS Command API documentation: wlan_scan .
- Note
- Call gos_network_scan_destroy_results() to cleanup the scan results
- Parameters
-
[out] result_list
Linked list of gos_scan_result_t [in] channel_mask
Bitmask of Wi-Fi channels to scan, leave 0 to scan channels in wlan.scan.channel_mask setting [in] ssid
gos_ssid_t specific SSID to scan, leave NULL if unused
- Returns
- gos_result_t result of api call
- Examples:
- wifi/wifi_scan/main.c .
◆ gos_network_scan_destroy_results()
gos_result_t gos_network_scan_destroy_results | ( | void |
|
) |
Destroy scan results list.
Destroy scan results returned by gos_network_scan()
- Returns
- gos_result_t result of api call
- Examples:
- wifi/wifi_scan/main.c .
◆ gos_network_softap_get_rssi()
gos_result_t gos_network_softap_get_rssi | ( | const gos_mac_t * |
mac,
|
int32_t * |
rssi_ptr
|
||
) |
Get the Received Signal Strength Indicator (RSSI) of a SoftAP client.
The returns the RSSI of a SoftAP client IF the interface it currently up and the client is associated, (i.e. if gos_network_is_up() returns true for GOS_INTERFACE_SOFTAP ). IF the interface is not up then this returns a result of GOS_NOTUP and the RSSI value is -999.
Use
gos_network_softap_client_list()
to get a list of associated SoftAP clients and coressponding MAC addresses. If the
mac
argument is NULL then the RSSI of the first client in the list is returned.
If RSSI averaging is enabled then the averaged RSSI is returned. If RSSI averaging is disabled then the raw RSSI is returned.
For more info about RSSI averaging, see Gecko OS Varaible API documentation softap.rssi_average .
- Parameters
-
[in] mac
MAC address of SoftAP client [out] rssi_ptr
Pointer to hold RSSI value
- Returns
- gos_result_t result of api call
◆ gos_network_verify()
gos_result_t gos_network_verify | ( | const gos_scan_result_t * |
scan_result,
|
const uint8_t * |
security_str,
|
||
uint8_t |
security_str_len,
|
||
uint16_t |
timeout_ms
|
||
) |
Verify WLAN network credentials.
This has the same functionality as gos_network_verify() but directly accepts the result from the gos_network_scan() API.
The security_str/security_str_len parameters depend on the security type.
- OPEN - leave NULL
- WPA/WPA2 - should be the PSK (64 HEX characters) or password (8 - 32 characters)
- WEP - should be the WEP key (10 or 26 HEX characters)
- Note
- Using a PSK instead of password makes the API execute ~3seconds faster.
- This API should wait for no more than 1second when the SoftAP is active otherwise connected clients will disconnect thinking the SoftAP has gone down.
- Parameters
-
scan_result
Scan results from gos_network_scan() security_str
Network password, PSK, or key security_str_len
Length of security_str timeout_ms
Maximum time in milliseconds to wait for verification
- Returns
- The result of the verification
