 ====== SDK Scripts  ======
+Within the SDK you can reach the gps data by requesting the status parameter as in the cli example or you can retrieve the data from the gps over IP daemon to distribute it further.
+Cli data can be retrieved as follows:

+status=nb_status("gnss");
+dump(status);
+</code>
+Result:

+==== SNMP ====
+It's possible to poll the postition via SNMP.
+You will find the entries "gnssLat" latitude and "gnssLon" longitude in the private MIB.
+Please be aware that the update interval will be 3s.
+===== Example Scripts =====
+  * Sending NMEA String on the serial interface: [[sdk:gps2serial]]
+  * Forward NMEA String to a UDP Server: [[sdk:scripts:gps-udp-client]]
+  * Enable/Disable WLAN depending on the current position: [[sdk:scripts:gps-monitor]]
+  * Creating CSV Logfiles with location data: [[sdk:connection-statistics]]
