I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference:
The baud rate you set must match the device it's hooked to. They have the default 115200 or switch to 9600 but if you need other (1200 in my case for a survey instrument) you need to set that up through hyperterminal* and a null modem cable.
*Though the docs for the bluesnap device suggest using hyperterminal there are issues with it. After a few calls to bluesnap, they suggested:
First, when connecting the device to a PC, try putting the Jumper settings back to their original positions using 115200 8, N, 1 and X off. When DTE enabled, a terminal connection cannot be established without using special software specifically designed for DTR/DTE connections.
Second, HyperTerminal has known issues with the BlueSnap. I would recommend trying TeraTerm or PuTTY.
took me 4 days to find this out!
