ARDUINO AND APP

Projects General Guidance
1

Hi, is it possible to have an Arduino send data to a BLE app on a phone? Thanks.

It is, but I haven't been able to figure it out, if you go on the google play and look around for Arduino App, there is one that is called Arduino Total Control and a few others, That one has both Bluetooth and WiFi settings, so maybe worth a look.

Yes

Bluetooth is like Serial-by-wireless.

What sort of phone?
The HC05 bluetooth module will work with an Android phone but not (AFAIK) with an Apple phone (which I can't afford). With an Apple phone you need a different module - no doubt a bit more expensive.

Thank you for your quick response.

Adafruit sells some Bluetooth modules which work with the iPhone.

A $3 HC-05 module mentioned by Robin2 works great with an Android smartphone.

For BLE, I'd recommend the HM-10. It is also fairly straightforward depending on what you are trying to accomplish.

Hi,
I've done this in many of my projects and my favorite Bluetooth LE modules are HM-10, BlueDuino Rev2, and ABBLEShield. They can be found on Ebay and RobotShop for example and are currently the cheapest BLE modules on the market.

I actually just made an app for Android that can be used to communicate with these BLE modules. If you're using Android check it out here: Bluo

If you're using iOS I think you can use LightBlue to send and receive data with the module (not sure tho, don't have an iPhone): LightBlue

If you choose the HM-10, I'd suggest the one with a breakout board (around $3 on Ebay). Here's a picture of the backside of one:

All you have to do is connect your Arduino to the BLE board like so:
Arduino VCC --> BLE VCC (make sure you feed the BLE board 3,3 Volts, not 5 Volts)
Arduino GND --> BLE GND
Arduino RX --> BLE TX
Arduino TX --> BLE RX

Now you have a serial connection between the Arduino and the BLE module and you can send data from your Arduino to your phone using BLE.

Let me know if u need more info.
