Tip

This library has its own demo,click this link to view lbsLoc2 demo examples

Example

-- Attention:
-- 1. Because sys.wait() is used, all apis need to be used in the coroutine.
-- 2. Only single base station positioning is supported, that is, the currently networked base station
-- 3. This service is currently in test status
sys.taskInit(function()
    sys.waitUntil("IP_READY", 30000)
    -- mobile.reqCellInfo(60)
    -- sys.wait(1000)
    while mobile do -- No mobile library, no base station location
        mobile.reqCellInfo(15)
        sys.waitUntil("CELL_INFO_UPDATE", 3000)
        local lat, lng, t = lbsLoc2.request(5000)
        -- local lat, lng, t = lbsLoc2.request(5000, "bs.openluat.com")
        log.info("lbsLoc2", lat, lng, (json.encode(t or {})))
        sys.wait(60000)
    end
end)

lbsLoc2.request(timeout, host, port, reqTime)

Execute positioning request

Parameters

Incoming Value Type	Explanation
number	Request timeout, in milliseconds, by default.15000
number	Server address, with default value, can be domain name, generally do not need to fill in
number	Server port, default 12411, generally do not need to fill in
bool	Request to return server time

Return Value

return value type	explanation
string	If successful, return the latitude of the positioning coordinates, otherwise it will be returned.nil
string	If successful, return the accuracy of the positioning coordinates, otherwise it will be returned.nil
table	Server time, East Zone 8 time. When the reqTime is true and the location is successful, it will be returned.

Examples

-- About Coordinate Systems
-- In some cases, it will return GCJ02 coordinate system, and in some cases, it will return WGS84 coordinates.
-- Historical data has been unable to distinguish the specific coordinate system
-- In view of the error between the two coordinate systems is not large, less than the error of the base station positioning itself, the significance
sys.taskInit(function()
    sys.waitUntil("IP_READY", 30000)
    -- mobile.reqCellInfo(60)
    -- sys.wait(1000)
    while mobile do -- No mobile library, no base station location
        mobile.reqCellInfo(15)
        sys.waitUntil("CELL_INFO_UPDATE", 3000)
        local lat, lng, t = lbsLoc2.request(5000)
        -- local lat, lng, t = lbsLoc2.request(5000, "bs.openluat.com")
        log.info("lbsLoc2", lat, lng, (json.encode(t or {})))
