(GPS transplantation trilogy) one of the common problems of porting GPS applications in Linux

Analysis and Solution to common problems of porting a GPS application in Linux 1: the reason why the GPS application cannot be started:

1. The GPS data path is incorrect;

2. Check whether the dynamic link library is correct, including the size and version;

Solution (steps and methods ):

1. Whether the file size of the GPS library and data in the mobile phone is consistent with that in the release directory;

2. Check whether the GPS data storage path is correct in the navione. ini file;

3. Whether the previous release version is normal;

 

Problem 2: Reasons for failing to receive the GPS signal:

1. The GPS parameters do not match the development board;

2. Whether the GPS antenna can receive signals;

Solution (steps and methods ):

1. Check whether the current development board is a Cayman, Fiji, or Bali.

2. Check whether the atgps. ini parameter in the current configuration file is correctly configured.

3. Is the gpstool tool running normally?

4. Go to the GPS antenna and put it out of the window or test it out.

Problem 3: unable to receive the GPS signal

First, check whether the atgps. ini file can be opened normally.

Second, whether the parameter configuration in the atgps. ini file is correct

1. Is the gpio port number correct?

2. Check whether the gpioreset reset port number is correct.

3. baud rate

4. gpio device path

5. Serial Port path

6. pumtool Power Management Tool Path
