libsoratun

The C library allows you to embed Soracom Arc connectivity into your own program. You can send a message to the unified endpoint, with Soracom Arc, entirely from userspace (no root privilege is required).

Tested Setup

• Go 1.21.5 darwin/arm64
• macOS Sonoma 14.1.2

Prerequisites

1. You have to have a virtual SIM, along with arc.json which is a configuration file for soratun locally. See documentation for detail.
