From 7f26a2d06410fd3a2768612b9c9daf869778e480 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Tue, 3 Jan 2023 00:51:50 -0500 Subject: Repurpose into gRPC service Repurpose repository into a spiritual successor of the previous binding. The backend code is retained behind a new gRPC API defined in protos/radio.proto. The simpler synchronous gRPC API had been used for expediency, this may warrant revisiting to rework into an async or callback API based server instead. As well, authentication has been left until some consensus on an approach can be worked out.
