◆ nrf_cloud_location_request()

int nrf_cloud_location_request	(	const struct lte_lc_cells_info *const	cells_inf,

		nrf_cloud_location_response_t	cb )

Perform an nRF Cloud location request over MQTT.

Parameters

cells_inf	Cell info. The required network parameters are cell identifier, mcc, mnc and tac. The required neighboring cell parameters are E-ARFCN and physical cell identity. The parameters for time diff and measurement time are not used. The remaining parameters are optional; including them may improve location accuracy. To omit a request parameter, use the appropriate `NRF_CLOUD_LOCATION_CELL_OMIT_` define. Can be NULL if Wi-Fi info is provided.
wifi_inf	Wi-Fi info. The MAC address is the only required parameter for each item. To omit a request parameter, use the appropriate `NRF_CLOUD_LOCATION_WIFI_OMIT_` define. Can be NULL if cell info is provided.
config	Optional configuration of request. If NULL, fall back to default which is do_reply = true, hi_conf = false, and fallback = true.
cb	Callback function to receive parsed location result. Only used when config->do_reply is true or config is NULL. If CONFIG_NRF_CLOUD_LOCATION_ANCHOR_LIST is enabled, the application should not access the anchor list data after exiting the callback as it may become invalid. If cb is NULL, JSON result will be sent to the cloud event handler as an NRF_CLOUD_EVT_RX_DATA_LOCATION event.

Return values

0	Request sent successfully.
-EACCES	Cloud connection is not established; wait for NRF_CLOUD_EVT_READY.
-EDOM	The number of access points in the Wi-Fi-only request was smaller than the minimum required value NRF_CLOUD_LOCATION_WIFI_AP_CNT_MIN.
