CCS: Import failed for project 'spp_ble_client' because its meta-data cannot be interpreted

Please try to explain what you did.

Hello Tom,

I ordered and received my CC2640r2 board.

I downloaded the github example 1.40 https://github.com/ti-simplelink/ble_examples/tree/simplelink_sdk-1.40

I imported the ble_examples-simplelink_sdk-1.40\examples\rtos\CC2640R2_LAUNCHXL\bleapps\spp_client

I compile OK. It just complained that I was running on 1.50 and used it.

I ran the the app on my board.

I tried again with spp_server and got this error

I tried again with spp_cleint nd could not succeed anymore.

I reinstall the full CCS vers. 8 and still get stuck on the fact that it will not compile anymore.

I do not get the same problem if I import the archive. But I cannot compile these examples anymore.

Thank you for your help.

Hello Jean-Marc,

could you try like this:
delete your project from a workspace with "Delete files from disk" marked ON,
open View -> Resource Explorer,
download the latest SimpleLink SDK and BLE packages for your MCU platform,
using the Resource Explorer search for 2640R2 and select your LaunchPad or a chip you are using,
in Software section find an example you need and import it,
build it
and let me know?

Thank you Tom,

I already passed thru this, and can confirm that other examples compile OK.

But what I need urgently is a Serial Port BLE to transfer data. I need an example to run and then modified, I have few time to develop from scratch.

It is mostly for testing and see how fast I can transfer serial data changing several parameters.

I thought the TI example was one of the best to "play" with, but I cannot compile it. Or worse, it did compile once but then no more.

If you have other idea to help I would appreciate.

I thank you again for your help.

Hi,

copy ble_examples-simplelink_sdk-1.40\examples\rtos\CC2640R2_LAUNCHXL\bleapps\spp_client code
into a working example and do what you need.

This is not possible because the problem is linked to the stack, any working example does not use the same stack.
Anyway this was a nice idea... :-)

Use View -> Resource Explorer to install XDCtools you need.
It takes months to understand CCS verions, examples, SDKs and links between them.
In most cases this staff works as expected.

Still encountering problem now to run the spp_ble_server_cc2640r2lp_app.
Description Resource Path Location Type
Invalid project path: Include path not found (D:\workspace_v7_server\.metadata\.plugins\com.ti.ccstudio.project.ui\volatile\ble_examples-simplelink_sdk-1.40\examples\rtos\CC2640R2_LAUNCHXL\bleapps\spp_ble_server\src\app). spp_ble_server_cc2640r2lp_app pathentry Path Entry Problem

I have no idea what path should I change or set.
Tried either version SDK 1.50 and 1.40, still not compiling...

Any clues?

Create separate empty workspaces for different CCS versions and import:
1. I found the same example for the SDK 1.50.
My recommendation: never use any workspace with different CCS versions.

Let me know.

Yes now I do so, thus I save m working set and do not disturb it.
But still the spp_ble_server_cc2640r2lp_app has a path entry problem and I am not enough smart on CCS to troubleshoot it.
Trying other solutions but I needed so bad this UART over the air for a test...
Thank you Tom

Please, give me a path to your project.

Thank you.
These are the docs:

www.ti.com/.../tidua63.pdf
www.ti.com/.../tidu997a.pdf
processors.wiki.ti.com/.../CC2640_UART_to_BLE_Bridge

This is the path to the GITHub spp server (all examples to clone), from this I import the archive ble spp server app

github.com/.../simplelink_sdk-1.50

This is the path to the spp ble server app:

github.com/.../ccs

Jean-Marc

1. github.com/.../simplelink_sdk-1.50 and download zip
2. unzip somewhere
3. Project -> Import CCS Project... from somewhere
4. select ...client...app... and ...server...app... and import
5. both build without any issue

Oh, Well, then something I do wrong...
This is exactly what I have done too, but when I import the project from the unzip (not archive) the project imports without the stack and I cannot compile. No way to compile just sits there, the compile button (the hammer) is grey...
How is this possible? what do I do wrong?

Thank you Tom for your fantastic help. If you have a clue of what I do wrong???

Or else, I get this message as already mentioned in the passed: "Import failed for project 'spp_ble_server' because its meta-data cannot be interpreted. Please contact support."

It depends from where I import it.

If I do it from "File open project from file system" then I get the problem I mentioned in my previous answer, if I import from project import then I get the message "Import failed....because its meta-data...."
