The BLE-290BWRY is available in two connectivity versions: SLIM Series (2.4GHz) requiring the CEDAR V3 AP gateway for centralized management of hundreds of tags, and BLE Series (Bluetooth 5.0) requiring no gateway — controlled directly from a smartphone app. Choose the version that best matches your store size and deployment requirements.
