Bluetooth 4.0 Low Energy module for independant wireless bracelet? Answered
I'd like to make a wireless bracelet linked to my phone via Bluetooth 4.0 Low Energy (BLE).
BUT, i can't find lots of information about BLE module.
In one hand, i found this special BLE Arduino : http://www.rfduino.com/rfd90101-teaser-kit.html but i think i won't power it with just a simple watch battery. Am i right? And if i have to power it with 2 AA battery, i won't build a bracelet...
In the other hand, i've read an Instructable topic about a vibrating bracelet (almost the purpose of me) here : https://www.instructables.com/id/ViBracelet/
The person uses a Bluetooth Low Energy module , ConnectBlue part #: OLP425i-26. It seems to fit my needs, but also seems to be more difficult to program as it is not an arduino of something else.
What do you think of that? I need advice...
Thank you for your time.
