Known Issues

Legato 15.05 Beta has the following known issues:

[App Mgmt] Apps OTA installation may not succeed if interrupted during download.

[App Mgmt] If Apps OTA installation doesn't succeed, the app will first have to be deleted from AirVantage, and then reinstalled again.

[Audio] le_audio_Play, le_audio_Record fail if called several times with the same file reference.

[Config Tree] Floating point conversion may not be precise.

[eCall] le_ecall_ExportMsd return erroneous msd.

[eCall] Erroneous controls flags in MSD send in only Mode.

[eUICC] BIP errors may be observed from Open Channel command.

[Modem] le_mrc_SetManualRegisterMode fails with -6.

[SMS] le_sms_CreateRxMsgList() returns NULL when SMS storage is full.

[SMS] SMS service fails if an incoming message has non-numeric origination id.

[Voice Call] Voice call notifications not properly handled.

Limitations & Constraints

[Upgrade] When upgrading to the 15.05 from a previous version, user will be asked to reset the target after running instlegato; symbol look up error messages may be displayed after the reset. The target will start successfully, and the error messages shouldn't be displayed again in the subsequent instlegato command. 

[Downgrade] When "downgrading" from a newer framework release to an older one, all apps should be removed from the target before installing the older framework.

[Upgrade/Downgrade] Configdb is restored to default after each Legato framework upgrade/downgrade.  App should make sure the configuration is initialized correctly.

Documentation

Services

The Services documentation was reorganized.

The Application and Foundation sections were combined into one Services topic. The topic contains links to all Services, descriptions, and lists services that are already multi-app safe (meaning arbitration is fully managed among apps so multiple apps can share the same resources).

New Services were added for Ring Indicator, App Status and SMS Inbox Service.

How To topics

A new How To section has been added with these topics:

o    Customize Legato Yocto USB (moved from PDF version in 15.01)

o    Manage Device Power

o    Debug Apps

o    Port Legacy Apps General

o    Port Legacy Apps C Language.

o    Use Logs

o    NMEA Port Setup

Format and Navigation

Data Structure tree was removed (never used).

About tree was moved to the top of left navigation tree. About Legato page now dynamically generates the release number (including tag). More details on using/searching the documentation and a Glossary were added. 

Stylesheet improvements: recognizing blank lines in code samples and left aligned graphics.

General

The Getting Started topics were reorganized to better reflect the installation process with new Target and Dev Host PC sections.

Basics topics to create new apps and components were restructured following coding changes.

Demo Apps topics were renamed to Sample Apps. Topics were split and more detail was added.

Other Info topics: Platform Constraints was added with an Audio Limitations topic and Yocto topics were moved from Getting Started.

Copyediting and various docs fixes were also included.
