8. Discontinued Features

Open AT Application Framework support

Developer Studio has reached a high level of feature completion and stability. Consequently, the next Developer Studio 3.6 is planned to be the final version supporting Open AT. We invite all users to report last bugs before End of September 2015 through your classical support channel or through forum.sierrawireless.com.
This 3.6 version is planned to be released by mid-November.

Discontinued features since Developer Studio 2.3.X versions

Support of Open AT Application Framework versions former than 2.5X (including older architectures like Open AT SDK and related hardware or features) has been discontinued starting from Developer Studio 3 release.
To continue using these features on former Open AT Application Frameworks, it is recommended to keep using Developer Studio 2.3.X versions and not to install 3.X releases, in order to ensure tooling compatibility with these frameworks versions.

Discontinued features since Developer Studio 3.2

Support of Mini Core and Multi Core projects features has been discontinued starting from Developer Studio 3.3 release.
To continue using these features, it is recommended to keep using Developer Studio 2.3.X or 3.2 versions and not to install future releases, in order to ensure tooling compatibility with these features.

Known limitations & bugs

1. Build system

• General:
  • Workspace paths with space characters are not supported
  
  
  
• Legato workspace with Boot2Docker build:
  • When building Legato projects through Boot2Docker (e.g. on Windows hosts), the Legato projects have to be physically located in the workspace, since only the workspace location is shared with the Boot2Docker VM.
    In other words, if a Legato project is imported from a location out of the workspace (without copy), the Boot2Docker build won't work.
  
  
  

2. Target management

• Windows 64 bits USB support for Open AT 3G/CDMA devices: Due to some unstability in the integrated native library managing serial ports handling, Developer Studio should crash when reset occurs on these devices.
• Linux USB support for Open AT devices: After a device reset with USB connection, sometimes the connection is broken since the USB port identifier has changed. It's necessary to close the port, refresh the port list and reopen the port again to resume the connection with the device.

3. Run & Debug

• Two breakpoints limitation when debugging on Open AT: When using embedded GDB on Open AT, the 2 active breakpoints limitation can cause unexpected behavior when 2 breakpoints are active and the step into, step over and step return actions are used in the debugger. It is recommended to disable breakpoints (or to let only one active breakpoint) to get a reliable behavior when using step by step debugging.
