Some good news. Using the MJLJ hardware with the MCU removed I can talk to the Bluetooth module via the serial port on the MJLJ. I get OK when I type AT and have been able to change the baud to 38400 using the AT+BAUD6 command and get the response OK38400. I have then gone back in using PuTTy at 384...

Quick question regarding changing the baud rate. I can't do it over the bluetooth connection as it needs to be in AT mode, so can I do it through the megajolt serial port if I pop the mcu out for safety?

I'll try that if I can ever get a bluetooth connection to talk to it. Trying a terminal emulator on the phone later.

Can't get it working :( . Unit looks exactly the same as the one in the link, but not the same as the one you have used on your board. Phone pairs with it ok, but no data at all. The device seems to be an HC-06 if that helps. The app doesn't seem to notice if I turn off the Bluetooth module until I ...

Only got a bluetooth dongle but it won't work on windows 7 even in compatibility mode... having trouble with my usb to serial connection to it too. Works occasionally. Need to try another computef as I've recently upgrafed from vista where it all worked to 7 and nothing works... will try more later ...

Got my module wired up and paired, but the gauges stay at '0' and can't get the map or anything from the Megajolt. tried swapping Rx and Tx... same result. Samsung Galaxy s II Android 4.

Any ideas?

Any progress with this one? I got an android device just for this project and that was 2 years ago now...

Is this project still happening?

Any more news on this?

Looking good. Swiping between screens sometimes takes about 9 or 10 attempts and occasionally requires a reboot of the app on my Samsung Galaxy SII.

How's the bluetooth hardware coming along? I would assume this could be tested with the standard tuner and a bluetooth dongle on the laptop?

the 15 pin port you describe will be a VGA output not serial. It's for connecting an external monitor.

any more news on this? My android phone arrives tomorrow and I can't wait to the 'Jolt tuning on it instead of the bulky laptop.

Looks interesting. Really want to see this happen.

The bluetooth adaptor I got from a Laptop is a broadcom bcm924nmd. It seems it's more of a USB interface jusdging by what I can find on pinouts... need to try it still, but not very hopeful.

Keep up the great work Brent.

Laptop module probably won't be suitable. Looking to purchase one of the proper units that say they'll convert any rs232 device to bluetooth. How likely is this tuning app will happen? Don't really want to buy the hardware if the app doesn't happen. Looking round, I can get an adaptor for about £35....

I'm looking into whether or not it would be possible to use an old bluetooth module from a dead laptop... got one on order from good old ebay... should be able to do something with it. Currently thinking it could mount in a small plastic project box and include a 9 pin serial port to connect to the ...
