The standalone GPS depends on GPS satellites to provide location information, while the A-GPS functions in conjunction with base stations as well as GPS satellites to improve the time to first fix (TTFF). The purpose of this document is to guide how to do the GPS test. Issue 01(2013-03-22) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 5 HUAWEI MU736 HSPA+ M.2 Module GPS Application Guide 2 GPS Test Procedure GPS Test Procedure 2.1 Enabling or Disabling GPS The MU736 GPS module can have its GPS function enabled or disabled. To disable GPS: Before the MU736 is powered on, pull down the GPS_DISABLE_N (PIN 25) pin. Then after the MU736 is powered on, GPS is disabled and cannot be enabled by using AT commands. To enable GPS: Before the MU736 is powered on, pull up the GPS_DISABLE_N (PIN 25) pin. Then after the MU736 is powered on, GPS is enabled and can be disabled by using AT commands. 2.2 GPS Test Ensure that the GPS antenna is located in an open sky environment. In Windows 7 or Windows XP On a computer running Windows 7 or Windows XP, use HyperTerminal to test the GPS. Step 1 Right-click My Computer, and choose Manage from the shortcut menu. In the displayed Computer Management window, click Device Manager in the left pane, and check for HUAWEI Mobile Connect-3G GPS Interface (COM 25) under Ports in the right pane. Issue 01(2013-03-22) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 6 HUAWEI MU736 HSPA+ M.2 Module GPS Application Guide GPS Test Procedure Step 2 Open the HyperTerminal and select the GPS port. Issue 01(2013-03-22) − 1) Click the icon . − 2) Select COM25 in the Connect using list, and then click OK. − 3) Select 115200 in the Bits per second list, and then click OK. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 7 HUAWEI MU736 HSPA+ M.2 Module GPS Application Guide GPS Test Procedure Step 3 The module starts to search the current location, and reports NMEA data. Issue 01(2013-03-22) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 8 HUAWEI MU736 HSPA+ M.2 Module GPS Application Guide GPS Test Procedure If the NMEA data contains latitude and longitude values (for example, 2231.8378,N,11356.6409E), it means that the module obtains the current location information. Step 4 Disconnect the GPS port on HyperTerminal to stop GPS location and NMEA data reporting. Issue 01(2013-03-22) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 9 HUAWEI MU736 HSPA+ M.2 Module GPS Application Guide GPS Test Procedure In Windows 8 On a computer running Windows 8, open a GPS-enabled map application to start GPS location. 2.3 A-GPS Test Step 1 Load the Secure User Plane Location (SUPL) server and certificate information onto the nonvolatile storage of the MU736 module. The MU736 module has integrated the server and certificate information, and no additional configuration is required. If an original equipment manufacturer (OEM) needs to load the certificate other than the integrated one, the OEM can contact Huawei to integrate the certificate into the PC Vendor tool. Once the certificate is integrated into the PC Vendor, one-click is required to load the certificate and relevant server information into the MU736 module. Step 2 Insert a SIM card that has subscribed to network services into the MU736 module. Then set up a dial-up connection. The MU736 starts the A-GPS positioning. 2.4 GPS Positioning in Windows 8 2.4.1 Using the Sensor Diagnostic Tool To use the Sensor Diagnostic Tool provided in the Windows driver program installation kit: Step 1 Connect the MU736 module to one of the USB ports on a PC. Step 2 Right-click My Computer, and choose Manage from the shortcut menu. In the displayed Computer Management window, click Device Manager in the left pane, and check for HUAWEI GNSS Sensor under Sensors in the right pane.
