Hi, I have a MC8704 module and I get an error when configuring the GPS.  
The sequence of AT commands for configuration is:

ATI3  
Manufacturer: Sierra Wireless, Incorporated  
Model: MC8704  
Revision: T2\_0\_2\_1BAP R439 CNSZXD00000128 2011/09/19 17:26:58  
IMEI: 357597040044541  
IMEI SV: 3  
FSN: CCP2651191510  
3GPP Release 7  
+GCAP: +CGSM,+DS,+ES

AT!CUSTOM?  
!CUSTOM:  
PUKPRMPT 0x01  
MEPCODE 0x01  
ISVOICEN 0x01  
PRLREGION 0x01  
PCSCDISABLE 0x03  
GPSENABLE 0x01  
OK

AT!GPSSTATUS?  
Current time: 1980 01 08 1 07:59:07  
1980 01 08 1 07:59:07 Last Fix Status = NONE  
1980 01 08 1 07:59:07 Fix Session Status = NONE  
No TTFF available  
OK

AT!GPSTRACK=1,255,30,1000,1  
ErrCode = 23  
OK

It seems as if the module did not have GPS capability.  
Revision module is: T2\_0\_2\_1BAP R439 CNSZXD00000128 2011/09/19 17:26:58

Please help!

Thanks

Hi, the response of AT!GPSPOSMODE? is:  
MASK: 0x00000000  
OK

Is it necessary to set the bit 0?

thanks

Thank you very much,
