BT Module - To turn off and on device

Support
1

Hi Guys,

I am new to this forum. I need some help and would appreciate if you guys can help.

I am looking for a bluetooth module the battery i have has output of 3.7 volt and its 250 mah battery.

I want a BT module which can work with both android and iphone. I want to turn on and off the this device using bluetooth.

I looked online and most of the BT module deals with Audio. I want a simple BT module compatible to the battery i have and is less expensive. I need it so that the product cost can be kept down.

Also the size of BT module should be something like HC-05 module.

Thanks.

Hey Bobby,

The HC-05 with a suitably programmed arduino should be suitable for your project. Another option is to use an Arduino nano 33 IoT such as the following that I’ve linked, which has bluetooth and microcontroller capabilities. Make sure to let us know how you go!
