1. New Features.

The Location Library  1.51 is an update release of Location Library 1.3 that does include following new features compared to Location library 1.3 release:

  • Host RTC: Location library/XM0110 use the Embedded Module RTC time to build its clock reference. Pay back is BOM saving (extra hw to generate/maintain the clock is useless) wo any TTFF performance degradation.

2.2 Deliverables

This Location Library release includes:
  • The Location Library  for Open AT: an Open AT library, ready to be integrated into customer application thanks to an high level simple and generic GPS API set. See “Location Library Development Guide” for API description and porting guidelines..
  • The GPS_AT_cmd sample application: an application offering AT commands on top of Location Library . This application is available in source code allowing customer to use it as an example, to integrate it in its application, or to enhance it. See “Location AT Commands Interface Guide” for description of the GPS AT commands implemented.
  • The SimpleSample sample application: This application is available in source code, starts the Location service and output the GPS position data to the user through AT responses. It is designed for use with XM0110 Development Kit Daughter Board with UART configuration and does not require entering any application specific AT commands.


2.3 Compatibility

Air Prime™ Intelligent Embedded Module compatibility list

WMP1x0* / Q2686G/87G** / SL6087


* 16Mb RAM or larger is required. 32/8Mb memory combo not supported, 32/16Mb memory combo supported but requires changing default memory mapping.

** Q2686H and Q2687H are not supported due to memory limitation.


GPS hardware compatibility list

XM0110 (XM0110 Daughter Board for Development Kit, or XM0110 based application)

OS / Firmware / Libraries compatibility

Open AT Framework 2.51 or later

Firmware 7.51 or later

OS 6.51 or later

WIP 5.53 or later

IMPORTANT: not compatible with Open AT Framework 2.34, Open AT Framework 2.35 / not compatible with Firmware 7.44 and 7.45

Tools compatibility list

Developer Studio: 1.2.0 or later

Tool chains: ARM_EABI_GCC and RVDS (ARM_ELF_GCC not supported)


2.4 Software Installation

To use the GPS AT commands, you can download the Extended AT Command Application binary on top of your Embedded Module Firmware. The .dwl application file is available from latest Open AT Framework SDK 2.51 (see Download tab on Location Library product page:

http://www.sierrawireless.com/productsandservices/AirPrime/Application_Framework/Libraries/Location.aspx ).

You can also refer to the AirPrime XM0110 Development Kit Daughter Board User Guide or to Sierra Wireless Discovery Tool GPS page to assist you in your first steps.

To integrate the Location Library for Open AT® to your own application, you must install the Open AT Framework SDK and include the “Location Library” in the Libraries tabs of your project properties. You can also create a new Open AT project based on the Location Library samples available in the SDK: the GPS Simple sample or the GPS_AT_cmd sample.

 

NOTE: Depending on your system memory, you may encounter Memory Allocation Error while loading the application binary on your Embedded Module. Please review

IMPORTANT: Due to memory constraints,

  • Applications based on Location Library are not compatible with
    • WMP1x0 with 32/8Mb memory combo. 32/16Mb, 64/16Mb, or larger must be used.
  • Applications based on Location Library may require to change Embedded Module storage space allocation. To check the current values use AT+WOPEN=6 command. The application size storage must be greater than the application binary size and can be increase by decreasing the A&D storage size with AT+WOPEN=6,XXX command.
  • Developer Studio project must be built with 1MB+ memory options.
    • If you are using Developer Studio 1.1.2 or later and create an application based on GPS_AT_cmd sample or Simple XM0110 GPS sample, this will be managed automatically.
