USB Bluetooth module communications

[sourour]

Dear all

Can any one explain how to use two bluetooth USB modules (the widely avialable modules, usually used to connect a PC with a cell phone) to make wireless communication between two microcontrollers ? The pupose is to use the Bluetooth in a control system.

Thanks

One way to do it would be with a USB microcontroller. Cypress Semiconductor makes a couple of them with an 8051 core. However, if you already have a microcontroller in mind that you'd like to use, then you need to find out if that is USB capable. You could write code to do it with a little additional hardware....this is something I've never done so I don't know how difficult it would be.

Otherwise, if you have an MCU you want to use and it doesn't have HW USB, then you could always go with a RS232 to USB converter. These are easy to come by and I think Cypress also makes them.

One more solution, there are many USB modules out there that take an RS232 stream. Go to https://www.kcwirefree.com

I've used their modules before and they are ridiculously easy.

Remember that you need microcontroller with USB Host, but not USB device !!!
