AGPS (Assisted GPS)¶
The AT@AGPS command is used to control the AGPS function. Enabling AGPS can obtain location information faster but consumes a little wireless traffic.
Example:
AT@AGPS=gl601###,0,,,,012F$
+ACK:AGPS,123456789012345,C031,10,0,,012F,20210407101530,1234$
AT@AGPS?gl601###,,0C37$
+QRY:AGPS,123456789012345,C031,10,0,1,1,0,,,,0C37,20210407101530,1234$
