serial_send_bytes
Send raw bytes as hex (binary protocols: Nordic DTM, HCI, etc.)
How to use it
Project documentation lists serial_send_bytes for the MCP Remote Access MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
