Connecting Android, Arduino and HM-10 Bluetooth LE modules!

HM-10 App Test

About

This is my first attempt to connect Android, Bluetooth LE/4.0, Arduino and a WS2812 LED strip. It's designed for use with inexpensive HM-10 BLE/BT 4.0 modules based upon TI's CC2540.

Blue Light app is derived from Google's sample code:

Contributions and improvements are very welcome, Android development is quite new for me.

Most of this is at a proof of concept stage but I hope to develop it further!

If you would like to install the APK, it's here:

Tested on Nexus 4, Android 4.4.2

Search Operations

It works on older Android kitkat devices, but the search function does not work on the new Android 11 version.

switching the mode in HM-10 module

How do i switch the mode of module? that is when any data acquisition is over, how should i go for sleep mode. the one way is send AT+SLEEP but if i'm doing that it will transmit the command to the paired module. I'm not able to get out from that issue. can just help me out in that?
