Blues (formerly Blues Wireless) is an IoT connectivity platform that provides Notecard hardware modules and the Notehub cloud service for routing device data from edge devices to cloud applications. The Notehub REST API enables developers to manage fleets of cellular, satellite, LoRa, and Wi-Fi connected devices across 130+ countries. Blues follows a consumption-based pricing model with no subscription fees, charging per ingressed event beyond a 5,000-event free monthly allowance bundled with each Notecard hardware purchase.
