ss12sms

ss12sms is a lightweight software component and protocol for handling SMS communications on embedded devices and mobile platforms. The name is commonly used to refer to a small, cross-platform library that abstracts the details of modem communication and provides a simple API for sending, receiving, and organizing text messages via GSM modems and SMS gateways.

Key features include support for both TEXT and PDU modes, management of delivery reports, and storage location selection (SIM versus device memory). The library typically handles multipart messages, character encoding (GSM 7-bit, 8-bit, and UCS-2), timestamping, and retry/error handling, delivering a queue-based interface to applications.

Architecturally, ss12sms is modular. A core dispatcher coordinates message flow, a modem driver translates API calls into AT commands, and a storage backend persists messages and status information. It emphasizes portability across platforms and modem types, with adapters for common platforms and open interfaces for custom hardware.

In practice, ss12sms is used in IoT devices, alert systems, and amateur radio projects where SMS remains a reliable channel for remote control or notification. Its open-source variants are discussed in hobbyist communities and are integrated into larger toolchains for remote monitoring.
