@marco.degano Thanks for the heads up! I’m glad your automation script works regardless. I noticed another user posted about this as well here.

BUG REPORT: Protobuf Version Incompatibility in Saleae Automation Package

opened 05:49PM - 25 Mar 25 UTC

## Issue Description When importing the `saleae.automation` package, users enco…unter a warning message about protobuf version incompatibility: ``` Protobuf gencode version 5.29.0 is exactly one major version older than the runtime version 6.30.1 at saleae/grpc/saleae.proto. ``` ## Technical Details - **Generated Files**: The `saleae/grpc/saleae.proto` files were generated using `grpcio-tools`, which specifies a dependency constraint of `5.26.1 <= protobuf < 6.0dev`. This results in generated code with version `5.29.0`. - **Runtime Version**: The package's dependency specification in the pyproject.toml file only requires protobuf to be greater than version `3.5.0.post1` without an upper bound. This allows pip to install the latest protobuf version (`6.30.1` at time of writing), creating a major version mismatch. - **Warning Trigger**: The version mismatch causes a warning to be logged whenever the package is imported. ## Impact Currently, this issue only produces a warning message when importing the package. However, future protobuf releases may break compatibility entirely, potentially rendering the package unusable. ## Steps to Reproduce 1. Create a Python virtual environment: ```bash python -m venv .venv ``` 2. Install the Saleae Logic 2 automation package: ```bash pip install logic2-automation ``` 3. Run a Python script that imports the package: ```python from saleae import automation ``` ## Recommended Solution - Add `grpcio-tools>=1.71.0` or some other version to the list of general dependencies. This will allow pip to see the additional constraint and avoid installing a protobuf version that is too high. ## Other Solutions 1. **Pin the protobuf runtime dependency** to match the gencode version (5.29.0) in the package's dependencies. 2. **Update dependency constraints** to prevent installing protobuf 6.x+ until compatibility is resolved. 3. **Update the build process** to use a newer version of `grpcio-tools` that supports protobuf 6.x.

I doubt it’s anything critical, but we’ll double check.
