Need i2c to Bluetooth converter

I have a couple of BMS'es with OZ890 micro controllers that I plan to use in battery packs for eBikes.
The BMS has an i2c interface that can be used to read status from the battery pack.

I'm looking for an inexpensive solution to add Bluetooth to the pack so I can create an Android app to monitor the battery.
There are many cheap i2c to USB interfaces to be found, and there are some fairly cheap Bluetooth chips out there. But I have not found a ready made solution combining i2c and BT, does such a thing exist?

already tried to reply to this on my phone but i guess it didnt send

I dont know of an all in one chip but you could have a arduino nano read the i2c bus and send over serial over bluetooth total cost about £15 and you will need to do the programming

a better google revealed this

new so it might not have been around when you looked the first time.

PS if you get this to work can you do me one for putting you on to this

I finish my masters in Computer science in a week so might start work on a similar Idea. Need to get a job though

Thanks for the ideas whereswally606, I'm more into software than hardware so was hoping to find something that does not require too much soldering

Perhaps this one will work with an Arduino Nano?

This is cheaper, they definitely work with the 328AVRs on UNO's and Nanos and it costs £4 or $8 ish so better than $20

depending on what you develop in, I use Java and getting these to communicate was tricky due to opening and closing ports on BT module. For java the
bluetoothDesktop library by Extrapixel.ch was absolutely critical. I have built a remote weather station with bluetooth waveguides for my masters in comp sci. My budget was ridiculously low.

I think this panasonic chip may be better in the sense that the coding will be all on the phone not on an arduino and phone if that makes sense. But i have no experience with the chip yet but for £4 i might look into it.

Just so you know, that's just a PCB for the serial module, you'd want to use something like this:

I used it with the cycle analyst to read the telemetry with an android app with pretty good success.

Thanks Bartimaeus, I just found out the hard way. Received two of the blank PCB's the other day, guess I should read the specs more carefully before ordering next time

A friend of mine just ordered a couple of these:

Seems to be exactly the same product as you suggested, we'll check them out once they arrive.

He is also getting this: http://dx.com/p/arduino-nano-v3-0-81877

Will report here if we get it to work.

You can also buy those modules on their own and solder it to the baseboard, so it isn't necessarily a total loss. You should let me know about how well the knock off Arduino works, I've been thinking about getting one.
