See various states in table below XM0110 ON ON when XM0110 has been powered ON PPS Controlled by XM Hz blinking when fix with good precision. ANTENNA SUPPLY Controlled by XM0110. ON when power is provided to Antenna Figure 6. AirPrime XM0110 Development Kit LED behavior The GPS STATE LED state is managed by the application as follows: GPS STATE LED state LED Off Fast blinking (125ms ON / 125ms OFF) Normal Blinking (500ms ON / 500ms OFF) Short blinking (100ms ON / 900ms OFF) LED On Application state GPS not initialized, not started, or in sleep / deep sleep mode. GPS start in progress (including GPS receiver firmware download phase when required). GPS started, but no GPS fix available. GPS fix available (2D, 3D or estimated fix) An error has been reported by the application. Check your HyperTerminal output Rev 3.0 June 15,

22 Quick Start Steps Common Issue Troubleshooting Application Download KO If you are using a Q268xH or WMP1x0 with a 32Mb/8Mb memory: the GPS application will fail to download (a download error message will show on HyperTerminal). You must use instead an AirPrime Q268xG, Q268xRD, or WMP with 64Mb/16Mb combo. If you are using a WMP1x0 with a 32Mb/16Mb memory: the GPS application will fail to download (a download error message will show on HyperTerminal). You must change the memory mapping with AT+WOPEN=6,384 command Any GPS AT Commands Returns ERROR If any GPS AT command returns ERROR without any error code, the application has not been correctly started. In this event, use AT+WOPEN=7 and refer to document [1] to learn about the root cause. In case an error code is associated to the ERROR, refer to document [2] to learn about error code AT+GPSSTART failure (+GPSEVSTART:0) If after AT+GPSSTART, GPS STATE blinks rapidly for about 20 seconds (i.e. firmware download attempt ongoing), and then you receive +GPSEVSTART:0 event, check that your UART2 switches are correctly set on the Embedded Module Development Kit (see ) GPS performances with passive antenna or GPS simulator The software default configuration assumes use with an active antenna, i.e. optimized for external LNA. In case the XM0110 daughter board is connected to a passive antenna or to a GPS simulator, this default configuration applies 10dB attenuation on the signal, degrading significantly the GPS performances. XM0110 internal LNA configuration must be used instead. It is set using the following AT command sequence: AT+GPSINIT=11 (to initialize the GPS application on UART with default hardware settings, without starting GPS) AT+GPSCONFIG=1, 0 (optimize receive chain for internal LNA) AT+GPSSAVE=1 (optional, to saves this setting after next Embedded Module reset or power off/power on sequence) Note: This command does not de-activate the antenna power supply. You still have to use a DC blocker if needed to protect your GPS simulator Rev 3.0 June 15,

23 Quick Start Steps Working with older dev kit daughter board version WM Location AT Application default hardware configuration is not compatible In order to use WM , the default hardware version should be modified by typing the AT command: AT+GPSINIT=10 at each startup, except if this HW configuration is saved thanks to the AT+GPSSAVE=1 command Limitations with SL6087 Development Kit The WM XM0110 hardware is not fully adapted to use with SL6087 Development Kit. The AirPrime XM0110 RESET (GPIO19) and GPS STATE LED (GPIO20) signals are not properly routed between the SL6087 and XM0110. This does not prevent the XM0110 standard operation but causes GPS STATE LED to not work and could degrade recovery mechanism in some forced reset error recovery scenarios. Please upgrade your dev kit daughter board to WM or later Rev 3.0 June 15,

All elements are defined in the subsections below. TP100 D100 D4 D103 D102 D101 Figure 25. LED Indicators and Test Point D100: (GREEN) Power Supply Indicator D100 LED is supplied by VBATT but LED supply is enabled by VCC_2V8. So when D100 is turned on, to mean a VBATT and VCC_2V8 are present. Figure 26. D100 Power Supply LED schematic Rev 3.0 June 15,

43 AirPrime XM0110 Development Kit Reference Manual D4: (BLUE) GPS STATUS Indicator. D4 LED is supplied by VBAT_DEVKIT but LED supply is controlled by GPIO managed by software application. See software documentation for explanation of on or flashing LED. Figure 27. D4 GPS Status Led Schematic D103: (YELLOW) XM0110 ON Indicator. D103 LED is supplied by VBAT_DEVKIT but LED supply is controlled by the AirPrime XM0110 ON/OFF signal. If J103 is positioned for controlling ON_OFF by GPIO then D103 follow the state of this GPIO. If J103 is positioned for turn-on permanently AirPrime XM0110 then D103 is permanently on. Figure 28. D103 XM0110 ON Schematic Rev 3.0 June 15,

44 AirPrime XM0110 Development Kit Reference Manual D102: (YELLOW) PPS Indicator (blinking). D102 LED is supplied by VBAT_DEVKIT but LED supply is controlled by PPS output signal from AirPrime XM0110. This signal is under AirPrime XM0110 firmware control. The PPS signal will provide pulse output only once GPS acquisition reaches sufficient accuracy to provide a reliable period. In particular, this requires a GPS fix to be obtained. Until such conditions are achieved, no signal will be output at PPS pin. Figure 29. D102 PPS signal indicator schematic D101: (YELLOW) Active antenna power supply ON Indicator. D101 LED is supplied by active antenna power supply provided by U5 LDO. LDO enable is controlled by LNA_EN signal from XM0110. This signal is under AirPrime XM0110 firmware control.
