Hi fellow Xda-devs,
I'm a software engineer.
I do alot with honda ecu software. This goes for programming and datalogging. The problem is honda talks TTL. I have an ttl->usb and ttl->db9 serial.
I really wanna use my app i created for pocket pc. I'm gonna buy a wizard now, i had an qtek s100 first. Both don't support serial port nor usb host stuff. I use a pl-2003 chip for usb->ttl. Which has a pocket pc driver.

I'm think of buying a BT->serial. So i will use BT->Serial->TTL.
This is a link i have found.

Please give advice/comments if it will work

I have also been looking for a bluetooth RS232 device. All of the devices I have found meet my basic requirements. Though, a couple of applications that I planning to develop, provide me with a couple of out of the ordinary requirements:

1) I own a MAS-TECH multimeter which has an RS232 connection for logging reading on a PC. The connection operates at 600 baud (600,n,7,2). All the bluetooth devices I have found only go down to 2400 baud.

2) I also need the device to support baud rate changes on the fly. I would like the AT+IPR baud rate command to change the baud rate of the bluetooth device, once the command has been sent to the destination device. All the bluetooth devices I have found support a range of baud rates, but can only be configured using specific commands or via an application. The worst case I have found is that the device requires a reboot following reconfiguration.

Does anybody know of such a device?
Anybody have any suggestions?
