⚠️ ALPHA RELEASE v0.5.1 - Not all samples have been fully validated. Version 1.0.0 coming soon.
USP provides an abstraction layer for scheduling and managing radio access across multiple modulations (LoRa, FSK, LR-FHSS, FLRC) and protocols (LoRaWAN). The library enables applications to request radio access, configure transmissions/receptions, and schedule operations with priority management.
- Priority-based scheduling - Manage radio access with configurable priorities
- Multi-modulation support - LoRa, FSK, LR-FHSS, and FLRC modulations
- LoRa capabilities - Full support for transmission, reception, and ranging
- Precise timing - Schedule radio operations with accurate timing control
- Asynchronous operations - Callback support for non-blocking execution
- Seamless integration - Built on Semtech's radio planner
