Hi all, I though of a small project and I’m looking for components.
I need a small Bluetooth module that has the HID profile.
I want to be able to send keystrokes and mouse movement without having to install special software in the host computer to interpret the commands received by bluetooth.
I looked at the sparkfun modules and they only seemed to support the serial port profile. Did I over look? Or I really have to look somewhere else?
Thanks
Hi UPS,
The WT32 should be suitable please check it out.

They also have a breakout board linked nearer the bottom of the page.

It’s been over a year… yet, this is the subject I am interested in… let’s see if anyone is still listening…
Wow, that bluetooth module (WT32) offers way more than I need (stereo music??). I was looking to retrofit a $100+ Thinkoutside RS232 like keyboard (best portable keyboards ever made - too bad the company no longer exists (ok, iGo exists - but that’s like saying CircuitCity or COMPUSA still exists)).
(Yes, yes, there is a Thinkoutside bluetooth edition of the same keyboard. But this question is about getting there with the keyboard I have.)
So, do any of the other bluetooth solutions here at sparkfun offer a more cost-effective, power-miser-management, smaller-foot-print, RS-232-to-HID-only solution?
If not, perhaps (and this is round-about) using this BroadCom BCM2040 chip:

in a new sparkfun design might be what I am looking for. But as this chip is designed to interface directly with a key matrix, a PIC or other processor will be needed to make the jump from RS232 to a simulated key matrix. The two chips wouldn’t add up to more than $20 in single quantities. Probably less (BCM2040 $7 and a middle-of-the-road PIC 18F $5). The board could be built here at the sparkfun PCB batch web page. Anyone got the time…?
Or, like I said before, do any of the current sparkfun bluetooth offerings “offer a turn key solution” (i.e. add a battery and they act like a bridge between ASCII RS232 and a bluetooth-keyboard-ready device like an iPhone)?
