We are distributors to Sierra Wireless Routers in our country, and want to extend our services to Fastrack as well, we just received a Fastrack sample to test it, but I spent whole 3 days trying to get the first GPS fix, applying all possible solutions I know, but I failed in all my attempts.
Starting from the specifications:
Boot-loader: V08b0k Firmware: R7.44 Open AT OS: 6.34
Developer Studio: 1.2 Open AT Embedded Software Suit: 2.34 C-GPS: 1.7
I compiled the Developer Studio/C-GPS v1 sample applications: QueryApp, QueryAppAiding and SimpleSample (some of them with minor warnings) and none of them got any fix, even for a 15 minutes in a clear sky open area.
Knowing that the GPS is already active depending in the following:
AT+WCFM=5 +WCFM: 00000471,0
And I already enabled antenna power using:
AT+WHCNF=0,0 AT+WIOM=1,"GPIO8",1,0 AT+WIOW="GPIO8",0
During all the tests, the GPS green LED flashes in the initialization phase, and then keeps its LED on, the console always indicates no fix.
Is there anything more I am missing? Is there a compiled, compatible and tested WDL version of any C-GPS v1.7 test program (in case the cause is the Developer Studio)? Is there any way to check that GPS antenna is functioning currently? Shall I bother Sierra technicals as it’s not common problem?
Any help would be appreciated! But please don’t simply say ask your distributor! as we are the distributors in our region.
