Gateway gRPC code simulating communication between an app and a simple neural implant with four electrodes.

The App and the device communicate through gRPC for getting and setting individual electrode states.

Running the server:

python ./python/gateway_server.py

Running the client:

python ./python/gateway_client.py
< see Client command formats below>

Client command formats:

get: get <(int) electrode number (0-3)>

set: set <(int) electrode number (0-3)> <(int) electrode state(>=0)>

Example:

In one terminal

PS C:\PATH\gRPC_Gateway> python .\python\gateway_server.py

In another terminal

PS C:\PATH\gRPC_Gateway> python .\python\gateway_client.py
please enter command: get 1
        getting electrode 1 state...
        electrode 1 state: 0
please enter command: set 1 100
        setting electrode 1 state to 100...
        electrode 1 state set to 100
please enter command: get 1
        getting electrode 1 state...
        electrode 1 state: 100

Compiling Proto to python

from gRPC_Gateway directory

# <python protoc compiler> -I<path to protos folder> --python_out=<path to new pb2 file> --grpc_python_out=<path to new pb2_grpc file> <path to proto file>
$ python -m grpc_tools.protoc -I./protos --python_out=./python --grpc_python_out=./python ./protos/gateway.proto
