CC2541EMK: SerialBLEbridge project using CC2541 mini kit

Part Number: CC2541EMK
Other Parts Discussed in Thread: CC2541, CC2540, CC2652R

Hi, I started to use CC2541 mini kit (cc 2540 usb dongle + cc2541 keyfob)

I am very beginner in this module. I am not sure if  my idea is correct or not.

My application requires cc2541 keyfob with UART function, so I found "SerialBLEbridge" ( In this application, they use SmartRF05 kit, but i don't want to use it.

I want to make cc2541 key fob can receive UART data, and then send data to CC2540 usb dongle using bluetooth, and then display it with BTool or display it with serial comm tool. 

1. what is role of SmartRF05 kit? can i just skip this module?

2. Is "SerialBLEbridge" correct for my application?

3. Is it possible to display received data through Btool ?


  • 1. SmartRF05 kit is the hardware to run SerialBLEbridge and it should be no problem to use CC2541 Keyfox hardware to replace it.

    2. If you mean to communicate data/message between your host and CC2541 Keyfob and use BLE protocol to send data/message from CC2541 Key fob to CC2540 USB dongle connection to BTool. This should be the correct reference design.

    3. Yes, the received data should be output on BTool console.

    By the way, CC2541 is a old BLE solution and I would suggest you to use state-of-art solution which is CC2652R instead of CC2541.

  • Hi,

    To complete the previous answer, I suggest you to review the page dedicated to the CC2541EMK device (this will clarify the question related to SmartRF05 kit).

    You may also want to use the simple serial socket example provided on our GitHub.

    Best regards,
