Greetings Atilano,

Yes, you will need extra hardware to connect the LP-EM-CC2340R5 to the USB port on your PC. The LP-EM-CC2340R5 is an evaluation module, meaning it does not have an onboard debugger nor a USB connector. Therefore, to connect it to your PC, you will need an LP-XDS110, which is an external debug probe that connects to the LP-EM-CC2340R5 via the 10-pin JTAG/SWD header.

Once this connection has been made, connect the LP-XDS110 to your PC via a USB-A to Micro-B cable. Refer to this link to procure the LP-XDS110: https://www.ti.com/tool/LP-XDS110#included, the necessary USB-A to Micro-B cable is included within this package.

Hi,

Could you please recommend a Texas Instruments key fob that is compatible with the CC2340R5?

Please see attached image as a reference only

Hello Atilano, 

The CC2340R5 will certainly suit that application, however, you will have to make the PCB that the chip will go on. We can assist with debugging software/hardware related issues in this process of creation, but it will ultimately be designed by you. 

Texas Instruments does not sell key fobs. You take ownership of the final product, TI will help you with the development process. 

Hi, 

Here are some links to some resources that can provide more insight into your design process, and answer potential questions you may have about Channel Sounding:

Since he CC2340R5 does not provide a built-in pairing mechanism when using Proprietary RF mode.

What Transceiver does Provide a built-in pairing Mechanism?

Does the CC2340R5 meet the "RED" Radio Equipment Directive regulation?

If not, which one does?

Hello Atilano, 

The CC2340R5 is not a transceiver, it is an MCU. On the CC2340R5 you can implement a software-based binding mechanism for Proprietary RF by following the guidelines in our SimpleLink Academy Labs which can be found at the following link: https://dev.ti.com/tirex/explore/node?isTheia=false&node=A__AV90OzltmQBguQnYg5IPLA__SIMPLELINK-ACADEMY-CC23XX__gsUPh5j__LATEST.

Furthermore, within our SimpleLink Low Power F3 SDK, we have provided examples which also give you a baseline implementation of this software based binding mechanism that I am recommending to you. You can find the examples in your file explorer by navigating to the install location of your SimpleLink Low Power F3 SDK, like so: C:\ti\simplelink_lowpower_f3_sdk_9_12_00_19\examples\rtos\LP_EM_CC2340R5\prop_rf. Look at the "rfEchoRx", "rfEchoTx", "rfPacketRx" and "rfPacketTx" examples in particular.

In addition, you can also reference our Proprietary RF User's Guide for answers to further questions that may arise during your custom implementation: https://software-dl.ti.com/simplelink/esd/simplelink_lowpower_f3_sdk/9.20.00.81/exports/docs/proprietary-rf/proprietary-rf-users-guide/proprietary-rf-guide/index-cc23xx.html. 

The reason that we do not provide hardware based pairing mechanisms for Proprietary RF is because this is a custom communication protocol. Therefore, we at Texas Instruments want to enable our customers to modify/personalize their Prop RF implementations as much as they'd like; hence the software offering.

We do not provide turnkey binding implementations however, we have these resources available to you to steer you in the right direction as you develop your own custom implementation.
