CC2540: cc2540

Ali Khan

Part Number: CC2540

Hi,
I created a board using CC2540 to work as BLE and USB bridge communication for MCU but unfortunately, it didn't work.
I followed a 3rd party reference design to make it.
I want to make a 2nd version of it.
Can you provide me some reference design to follow for this application?

I simply need two features

BLE
USB bridge to program a MCU

I also have previous design if someone can review it and give me feedback to find possible issue.
I already got layout review so i need circuit review in this case but not pcb design review.

Thanks

Hi,
Thanks for your reply.
The problem is that this design, has BLE feature and USB communication but i need to use CC2540 as bridge between USB and MCU.
If i have to program a MCU then i need a USB bridge IC like FT232.
I need reference design for that so i can use already available firmware.
Thanks

Hi,

I am afraid TI does not provide the exact reference design you are asking for.

For the software implementation, I recommend referencing §5.5 of the following document https://www.ti.com/lit/swru222

I hope this will help,

Best regards,
