Problem with BLE stack 2.1 when building projects.

Hello all,

I have been working on a project based on glucoseSensor using BLE stack 2.0 for some time and faced some issues with the MTU size limitation. After I searched a little bit I found out that the new BLE stack 2.1 solved this issue. So I downloaded BLE stack 2.1 and installed it. I also updated my ARM compiler tool to 5.2.5. Do I need to update any thing else or uninstall anything from the last version for this version to work properly?

The problem is that my projects won't function in this new version. When I checked the sample projects like HeartRateSensor provided in the BLE stack 2.1 I got the warning "This project contains unresolved buildable linked resources..." when building the stack project. when I check it with the LightBlue App the Services won't be discovered and there is a problem in service discovery. I didn't face this issue with the version 2.0  and I don't know what to do in order to solve this problem. any idea? 

  • I have to make a little bit update,
    The Warning problem was solved but the service discovery problem still remains. I am connected to the device and I receive the advertisement data but the services won't show up. Is it possible that it is because of the app I'm using? BLE utility app also has the same discovery problem.
  • Hello,

    Indeed, the MTU issue was addressed in V2.1. However, this is some minor porting that is required. Have you implemented the changes in the Porting Guide on the TI BLE Wiki?
