OrangeLink – Public Beta

We are currently in test with 450 Beta Users please see the Facebook OrangeLink Beta Group for details.

The OrangeLink is a compact, lightweight, RileyLink compatible device designed using an all new nRF52810 Bluetooth 5.2 System on Chip (SoC).  The OrangeLink includes both 433MHz and 916MHz antenna’s, and uses 2 AAA batteries for 2 weeks of runtime without having to charge the device.   The OrangeLink also includes a vibration feature that notifies the user when the battery is low or if the OrangeLink is disconnected from a phone app.  The design matches the same dimensional specifications as the Apple AirPods™ and fits many of the AirPods™ Protective cases and accessories.

This is the Public Beta of the OrangeLink.  We have completed an Alpha test with 25 users for the last 6 weeks.  During the Alpha we identified a couple of minor UI reporting issues, and were able to post firmware updates for users to download.  This is a public BETA test with a larger user population.  Please join the Facebook Discussion Page or check back here for Firmware updates.
