RpcClient.ino File Reference

Detailed Description

Example demonstrating HTTP streaming RPC client.

This example shows how to:

• Connect to an HTTP RPC server (e.g., RpcServer.ino)
• Send RPC requests using SYNC, ASYNC, and ASYNC_STREAM modes
• Handle responses and streaming updates
• Manage connection state with callbacks
• Visualize progress on LEDs

Prerequisites:

1. Start RpcServer.ino first (on localhost:8080)
2. Then run this client to connect and send requests
