Looking for cheaper blue tooth module
« on: February 23, 2013, 03:33:55 am »
Hi, I am working on a project for school that uses blue tooth to send data from one microcontroller to another microcontroller. the cheapest blue tooth module i have found were these http://www.parallax.com/StoreSearchResults/tabid/768/List/0/SortField/4/ProductID/890/Default.aspx?txtSearch=blue+tooth. i was wondering if any one knew of a cheaper blue tooth module.

Nice.  Link Bookmarked.

Under 8USD shipped.  Seriously.  I love China sometimes.

when you buy in china, the deal is that you buy 20% more to repair if it fails ...
if it fails too much you loose, if it does not fail you win !
the modules from parallax or others come from china too but they do the repair so that explains the high price
also the characteristics of the module is not mandatory the same you must have some tries.

I have used a module like that, and MCU-PC communication worked very well; however, MCU-MCU communication may not be possible and requires some hacking.

A better way might be with these two modules:

Slave: http://www.ebay.com/itm/New-Mini-3-3V-wireless-Bluetooth-Transceiver-Slave-Module-Serial-Port-30ft-TTL-/261053259306?pt=LH_DefaultDomain_0&hash=item3cc7fc9e2a

I am currently using these modules for my Astro-photography right this moment. They work a treat. I have been using these for about 2 years without skipping a beat.
