Dear Ketiljo

Thank you for your good suggestion. I tried it, it's very perfect.

Best regards,

There are two ways to use DTM. The first is 2-wire UART, which is supported, the other is HCI, which is not supported. You need to setup the CMW500 to use the first.

The DTM on the nRF51 doesn't accept HCI commands.

Dear Ketiljo

Yes, we use 2-wire UART connect UART turn USB tool(CP2102). Then we connect it to the PC and CMW500 USB port.

The PC can use NRFgo or NRF CONNECT DESK to control. But we use CMW500, it can't control and test the device.

I read this link https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v12.3.0%2Fble_sdk_app_dtm_serial.html&cp=8_5_10_4_4

It shows DTM program support using MT8852B to test. I think it can support CMW500.
So, did you mean it did not support CMW500 to test?

Best ragards,

You must use 2-wire UART, the nRF51 DTM doesn't support HCU directly.
