Blues

aid: blues-wireless
name: Blues
description: Blues (formerly Blues Wireless) is an IoT connectivity platform that provides hardware modules called Notecards
  and a cloud service called Notehub 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. Developers
  can use the API to retrieve device events, manage projects and fleets, configure routes to downstream cloud services, and
  monitor device health. Blues follows a consumption-based pricing model with no subscription fees, charging per ingressed
  event beyond a free monthly allowance bundled with each Notecard hardware purchase.
