Hi, at the moment I'm experimenting with Adafruit Feather 32u4 Bluefruit LE. I bought 0.8" 8x16 LED Matrix FeatherWing Display - Yellow-Green. In this video (3:01 minute) he , using the Bluefruit LE application Color Picker, sends a color value over to the board in RGB format. I want to ask, if someone has a Arduino code so I can also control the led matrix display with Bluefruit app?

Hi! Have you only used it on Arduino? Because I'm trying to use this module with Mbed, any guide for the Mbed environment? Heeeelp

Honestly, while I would be all for Bluetooth using less power, from my experience, devices that use the Bluetooth Low Energy standard often have issues with range, connectivity, and even latency. It’s particularly caused me many problems on my Sony 43 inch X800D, literally a 4K Android TV, which has noticeable input lag at times when using a Bluetooth Controller for emulators. This is why I often groan when I see it listed in specifications.

Think multiple RPi Wi-Fi range extenders around a building, a BLE advertising beacon to the nearest range extender paired with automatic WiFi network switching protocol. Boom.

Always enjoy your videos! Also, curious as to the trade off in power consumption in "Normal" Bluetooth vs B*LE. You have an app continually running to scan for devices and data as opposed to an app that is continually connected to Bluetooth or connects automatically within range? Seems like the winner is the B*LE PCB only taking cyclical scans? I am not being critical because I do find any energy efficiency related products amazing but, I do look at the other end as well or like to see the data behind the claims of lower energy usage.

Wait second..the Bluetooth logo is a B! I feel like an idiot for not seeing that before.
this is so helpful...thanks

Thanks Collin & Adafruit. Aside from BLE, what are good temperature sensors to use? I hate these DHT-11 & 22 They got a lot of issues like limited range, slow reading...etc.

BLE 4.0 is EASY for ANDROID !?!?!? Ummm seriously, it's like 100 times more difficult then the standard bluetooth....

I don't understand how this technology wouldn't be good for music. You can just send the information straight to the speaker, and it plays the song, and when the next song comes up on your phone, it can automatically send the information. Can't you do that?

As Collin described it, BLE is good for intermittent short-burst data transmission. Not so good for streaming data, which is what you'd do with a BT speaker.

Hello Colin, Enjoy the show, if i may ask how r where could i find a possibility to ADD bluetooth to an existing standalone speaker. Basically i kinda exspect some sort of arduino diy etc But please feel free to mention if its difficult, worth it or actually possible. thanks,

Beacon? So would this make it good for a lost bike or dog, or best kept indoors for keys and lost remotes?

Everyone who likes programming Arduino and Android needs to discover APDE. It is an indescribable joy to be able to program a portable device on the go with processing. a great prototyping language IMO.
