C-GPS samples not working when used on Q26 Extreme Dev Kit when using UART2 to connect to GPS. This is due to GPIO01 state (high) after reset. Application must initialize GPIO01 to low level at startup (using adl_ioSubscribe, or using AT+WIOM=1,”GPIO01”,1,0 command)

C-GPS QueryAppAiding sample is not functional with Q26Ext module. The CCED command answer is not correctly process by the sample.

There may be a shift in the UTC time between the GPZDA sentence and the GPRMC and GPGGA sentences in the NMEA outputs. This may occur during extended runs (more than 12 hours).

NMEA frames

In the NMEA sentence “$GPZDA”, the date field that indicates calendar date is occasionally wrong for one epoch.
- Incorrect sentence (3rd sentence) looks like this ( note date 15,02,2009 is incorrect):
$GPZDA,022540.963,22,02,2009,,*52
$GPZDA,022541.963,22,02,2009,,*53
$GPZDA,022542.963,15,02,2009,,*54
$GPZDA,022543.963,22,02,2009,,*51

6. Memory requirements

The C-GPS Plug-In memory footprint depends on the tool chain used:

Tool chain

C-GPS

Library only

QueryApp

Open AT® Application

GCC

ROM

370 kBytes

466 kBytes

RAM (Static)

70 kBytes

92 kBytes

ADS

ROM

303 kBytes

370 kBytes

RAM (Static)

70 kBytes

90 kBytes

NB: For Memory footprint: The ADL library RAM and ROM sizes should be added to the C-GPS Plug-In sizes to estimate the global RAM and ROM footprint.

NB: When using GCC sample with a 32Mb Flash size, platform must be configured with “AT+WOPEN=6,640” to allow enough room for the sample image for the download. Otherwise the platform does endless resets, repeatedly issuing “Fault 0400000000 !” after download.
