Protobuf files for defining ESP Local Control message structures
The proto files under this directory are used by esp_local_ctrl for defining protobuf messages which are sent and received over protocomm transport layer. These proto files cannot be used directly and have to be compiled into C and Python files. The generated C files are used by esp_local_ctrl itself to create, delete and manipulate transaction packets. The generated Python files can be used by python based applications for implementing client side interface to esp_local_ctrl service running on a device.
Note : These proto files are not automatically compiled during the build process.
Compilation
Compilation requires protoc (Protobuf Compiler) and protoc-c (Protobuf C Compiler) installed. Since the generated files are to remain the same, as long as the proto files are not modified, therefore the generated files are already available under components/esp_local_ctrl/proto-c and components/esp_local_ctrl/python directories, and thus running cmake / make (and installing the Protobuf compilers) is optional.
If using cmake follow the below steps. If using make, jump to Step 2 directly.
Step 1 (Only for cmake)
When using cmake, first create a build directory and call cmake from inside:
mkdir build
cd build
cmake ..
Step 2
Simply run make to generate the respective C and Python files. The newly created files will overwrite those under components/esp_local_ctrl/proto-c and components/esp_local_ctrl/python
