Interfacing with cell phones

Hi there

I am trying to find the easiest way to connect an arduino to a cell phone. So far my options seem to be

using rf transciever - ? needs additional hardware on cellphone end

using cell phone as a hot spot and connect via wifi

blue tooth

I am looking for
very low volume traffic, literally a few bits of data,
low energy consumption,
cheaper the better - to be left as sensor network.

I am in the very early stages of planning a wearable sensors around joints - for fun than anything else.

Any guidance, ideas, suggestions?

Thanks

For low energy bluetooth is the way to go but what make/model of phone do you intend on connecting too?
Most all the BT modules for arduino use SPP protocol (serial) and some mobiles have difficulty/won't support that method.

I am looking to use android phones - mine is samsung note but hope to be able to make it usable for most modern android phones. Looking at the HC05 and other bluetooth solutions, they seem to be a whole breakout board. I am wondering if these can be made to be as small as possible - to make it easier to wear. Are there any bluetooth chip solutions such as complete transciever module on a chip-I saw some from TI but am a complete noob. Thanks for help.

You would also need some form of microcontroller/power/sensors/indicators connected to the BT module as its not much use on it's own.
Google will help

are a couple of possibilities.
Or maybe you will want to make your own custom hardware?

I will look at the links now. I have some of the other sensors in mind, such as stretch sensor, temy sensor etc. Nothing finalized yet but ideas . My plan is to attach these sensors to b arguing and send data to cell phone some how. Data rate will be once every few seconds or so. I could see the data on the we prom or such but sending it to cell phone gives many more possibilities.

Thanks
