Interestingly, it looks like no issues about Arduino have been posted to the grpc/grpc repository. I have seen other github or other source repos that offer Arduino platform services for gRPC using Python or Node, but no issues on the grpc/grpc repo. 3. grpc/http2 max concurrent stream limit > > We read that grpc server can set max concurrent stream limit.

A bunch of different resources are linked from https://github.com/grpc-ecosystem/awesome-grpc .
