DTM software to work with R&S CMW500

Hi all,

I would like to work on KW45B41Z-EVK board with R&S CMW500 equipment for BLE testing directly but I found the following problem on it.

1) R&S CMW500 can recognize the USB visual COM driver for the kit but I cannot find the driver file for the MCU-Link and my equipment seems to be windows based system so I need how to download windows driver for the kit.

2) For the software running in EVK, I load the example code of hci_bb_bm code on it and it can run Generic FSK connectivity test demo software thru TeraTerm and try to connect this COM port into CMW500 and the initial check on the DTM connection with equipment is passed but EVK board seems to be not able to response to read test command from equipment and then making any BLE RF PHY link testing.

Therefore, I don't sure any specific software from NXP to be fit with DTM interface with equipment directly or any advise for using hci_bb_bm software to run with DTM with standard BLE tester equipment included R&S CMW500.

Hello, hope you are doing well!

This application note provides the RF evaluation test result of the KW45B41Z-EVK for BLE applications using the connectivity_test and HCI_bb application examples: AN13228 KW45B41Z-EVK RF System Evaluation Report for Bluetooth Low Energy Applications
