Bluetooth on the cheap.
Posted: Sat Mar 09, 2013 2:08 pm
Firstly l'd like to say Hi.
Making my first post here. I've owned a nistune chip for a few years, just finally getting around to joining the forums.
I decided to have a crack at a cheap bluetooth consult adapter using all parts from deal extreme (took awhile to arrive but free shipping)
bluetooth board
http://dx.com/p/db9-rs232-wireless-blue ... ule-104301
$11.80
basic serial consult adapter
http://dx.com/p/nissan-consult-14pin-in ... ool-128391
$26
voltage step down transformer
http://dx.com/p/dc-4-40v-to-dc-1-5-35v- ... mer-126108
$3.50
total $41.30 US
I could have used my original consult adapter and saved the $26US but decided i wanted to leave that one unmodified.
Putting it all together is straight forward, requires soldering.
Remove the consult circuit board from its housing, tap into the 12v and GND to power than step down transformer.
On my adapter 12v is a blue wire and gnd is purple. Adjust transformer until its output reads around 3.3volts.
Connect the output from the transformer to the power input on the bt board. (labeled + and -)
Now plugging the bt board into the consult adapter everything should function.
To make it one compact unit. I removed all the db9 connectors and wired the bt board directly to the consult adapter
then insulated the bt board and transformer and housed them inside the consult adapter casing.
To make them fit i had to remove the consult LED and rear piece of plastic that the screw screws into.
I've only done a small amount of testing but so far i haven't had any drop outs with my notebook.
Also tested it on my android phone using a free app called BlueFRom
Not sure if its useful for tuning but if you don't have your laptop with you, perhaps helping a friend fix their car and
want to quickly check the status of something or check errors codes on your phone then this is a good solution.
Cheers
Lance
