| * Synopsis: location_saraR52_SpotNowDemo_advanced.atl | ||
| * Topic: location_features | ||
| * Version: 1.0 | ||
| * Author: dtro | ||
| * Description: | ||
| * This script has the purpose to demonstrate the use of SpotNow. | ||
| * The script send a SpotNow position request counter_spotnow times | ||
| * every pause_between_spotnow_request ms. | ||
| * The script needs a valid SpotNow ZTP set that can be set with the | ||
| * +UGLAASZTP AT command (info in UBX-22003096). | ||
| * To setup the EVK-R5 double UART please refer to the EVK user | ||
| * guide (UBX-19042592). | ||
| * In addition, the SpotNow tunneling is enabled in the AUX UART | ||
| * port to inspect the UBX strings provided by the sensor. | ||
| * The script configures the baudrate to 115200. | ||
| * m-center AT interface must be configured to 115200. | ||
