This KBA deals with locating and downloading the wireless mesh stacks. If you are looking for information on getting access to the stacks, go here.
Simplicity Studio v4 allows for easy integration of the stacks within the development tools. Using the easy to use Package Manager, you can quickly download stacks and have them ready to use within just a few minutes.
To download the stacks, you first need to go to the Launcher perspective of Studio and click on the Update Software button which can be found in the tool bar.
The stacks appear in the SDK Tab of the package manager (you might need to click through the Installation Manager windows to get to this page).
Within this tab you can find all of the available stacks for you. They are sorted by categories. The view allows you to see all categories or just narrow down to a single category, like EmberZNet or Thread. You can also choose which versions you want, looking at just the latest, all available versions or the ones you have installed. You can also look at the versions which match a version of the Gecko Suite, so you will have the matched versions of different stacks.
If you have access to unreleased stack versions, certain beta stacks can be found within the Early Access tab.
Be mindful that not every stack is available through Simplicity Studio, only stacks from around mid-2016. Most components like ECC Libraries are also not found within Studio either. For these you will need to locate them within the support portal.
If you want to install the stacks separately from Studio or are looking to locate for packages that are not available within Studio, you can locate them within the support portal. This includes older software like the ISA3 Utilities and Ember Desktop.
To locate these, you will need to log into your portal account and click on the Software Releases tab within your account. From there you can use the pulldown menu to change display options, the All Software tab shows everything if you are looking for that.
Contact support with any questions or problems.
