Nordic Thingy Bluetooth Speaker Control

[Erke Can Tellal]

Dear Nordic Development community,

I have a very interesting project going on based on bluetooth speaker controls.

In short words, i'd like to control the sound level of a speaker by Nordic Thingy's 9-axis accelerometer. For example, if you lift the Thingy from its original position the sound should go up, and if you lower down the Thingy the sound level should go down.

However, the Thingy is a barely new product and I couldn't manage to understand how to send the sensor output data to an another bluetooth device or a micro controller (Arduino+Bluetooth shield) apart from the smartphone.

Basically, I'd like to read the sensor output data from the Thingy by Arduino+Bluetooth shield in order to use for controlling the audio level of a speaker.

Thank you very much,

Erke

PS: One other important topic is the question of stream pairing. For example, i would like to use the Nordic Thingy as a medium for pairing the audio streaming source (Smartphone, PC or any bluetooth device) and an another bluetooth speaker.

Just a footnote: be careful, basically all Bluetooth audio applications are BT classic aka BR/EDR not LE. If you do it through some "hub" like mobile phone/tablet/PC which has both BLE and BT classic capabilities then it might work. Otherwise make sure that your "middle man" is able to connect both Nordic BLE chip in something like Thingy and wireless speakers. I would say connecting directly Thingy with some off-the-shelf BT wireless speaker or headphones won't work (also because BLE as well as BT classic are pretty much always point to point so whatever more complex must be routed through application layer meaning you need to have some programmable device - like Android phone, Arduino with some shields, Windows PC - to make such application).
