Hello Folks!

UPDATED: During the presentation Ratio will provide access to the source code for a BLE service which implements these workarounds, and greatly eases integration of BLE into Android applications. Ratio will also raffle off 10 TI sensor devices to developers, so you can get started on BLE apps right away.

Continuing our theme on Bluetooth Communications, I'm delighted to offer Matt Reynolds the stage. Matt is a long-time SeaDroid member, and has been engaged in a variety of schenanigans, trials, tribulations, and successes using Bluetooth Low Energy as he builds out products for Ratio. As a nice counterpoint to the previous presentation, if you'd like to hear more about how BLE succeeds and, more interestingly, fails, then this will be full of interesting goodies.

In his words:

With the release of Android 4.3, Bluetooth Low Energy is supported on Android. In contrast to Classic Bluetooth, Bluetooth Low Energy (BLE) is designed to provide significantly lower power consumption. Unfortunately, there are significant problems with the BLE implementation that require extensive workarounds. This presentation will discuss the problems that we encountered in a real-world BLE application, the workarounds we implemented and the issues that are still outstanding.

Our hosts for this meetup will be Ratio, providing food and drink to the attendees:

Ratio delivers multi-screen apps providing consistent and optimized user experiences across the web, mobile, tablet, Connected TV, and console ecosystem. Ratio is privately held and headquartered in Seattle, WA. To learn more about Ratio, visit or follow the company on Twitter @teamratio.

As always, we will start around 6:30pm with some social time, and then presentations will start around 7pm or when people look like they're starting to settle down.

I look forward to seeing everyone there!
