Bluetooth Dongle Question

[scaven92]

I have been working with an Ezurio Bluetooth Developement Kit. I have some USB bluetooth dongles I would like to interface with it, but not via the PC. How can I find the info (datasheets, etc) so that I know how to interface this with a PIC?

The device is has part numbers IS1612N-204 on the big chip and K24C08 on the smaller chip. I tried searching for information, but could not find anything. What would you recommend I do? Its not a necessity that I use these, but I got a bunch for a $1 a piece and would like to incorporate them.

I am looking to interface this via serial communication with the PIC and would like to have the AT command reference.

Thanks for the help, I imagine this isn't an easy thing. A simple point in the right direction will do alot!

With a google search I have found this company selling OEM BT modules (product code: BM1612NMA) with IS1612N controllers in them. I suppose they will provide you full documentation of their modules if you buy at least one module from them, maybe without buying also. A subset of their documentation might be the chip's datasheet or interface description. There must be somewhere the IS1612N datasheet available directly..., I could not locate it so far.

The smaller chip K24C08 is a serial EEPROM, the datasheet is here.

I use the EZUiRO Parts - for interfacing to a PIC why would you want to use USB? That's a whole huge driver/stack issue.

I use their embedded modules - these things interface via Serial - Very easy and no software stacks - just fire up a UART and start talking away to the device.

They use AT commands like a regular phone MODEM.

Inside the devices use the CSR chips (csr . com) with EZUiRO's software stack inside (the AT command interpreter).

Very easy....

Thanks for the information.

I have one Ezurio chip and it is very easy to interface, I was just trying to tackle the workings of a USB dongle too without purchasing another Ezurio unit.
