conflicting Nordic Dk with Texas programmer ?

[MDF]

Our product consists of a Texas MSP430 and a Nordic nRF52832 Chip, with serial/UART between

for MSP programming, debug and development : I'm using the official TI MSP-FET Flash Emulation Tool (USB device)
for Nordic : I have a nRF52DK-52832 (PCA10040), several 52840 dongles (PCA10059) and the final hardware with 52832

When the Texas MSP is connected via USB most of the Nordic stuff is not properly working:
- It seems I can download code with Segger Studio into the PCA10040, but it crashes right after start
- I wonder why nRF Conenct for desktop lists the Texas MSP programmer as valid device
- I cannot use the 52840 dongle for Bluetooth with nrf connect for desktop, is just brings an error=-1

The MSP programmer works without problems, it can download code and debug - and when I pull it off my computer USB, all the Nordic things work again. Just plug it in - no need to start any session with Texas' code composer - Nordic tools are not working right.

Anyone experiencing a similar issue ? This is most annoying since I need to develop and work with both controllers

thanks for any advice, Matthias

sorry, I just tried it again and I still have the same problems.

- I'm using nRF Connect for Desktop 3.11.1 and installed all pending updates
- I started the BLE tool, bluetooth low energy, v3.0.1

- then I inserted my 52840 dongle into USB, ok, its reported as "nRF52 Connectivity" with Mac/ID F10A03B824B0
- I select this device and hit "start scan" and everything works

- now I stop this tool and plug in my Texas-Instruments MSP -FET Flash Emulation Tool into USB
- start again nRF Connect BLE
- and now I see both, the 52840 dongle and the Texas MSP Tools Driver, like this

when I now select the dongle, like above, I see these errors in the log window and I'm not able to use the dongle anymore

I did not start Texas' Code Composer Studio - its just enough to connect the MSP-FET programmer to USB in order to "confuse" the BLE tool and the same things happens when I'm trying to use the BLE programmer tool.

While the Texas MSP-FET is plugged to USB, I'm not able to use the nRF Connect tools.

I already showed this (teamviewer session) to your german technical colleague a few weeks ago, but at this time I was not aware that the trouble seems to be caused by the Texas programme. I can easily repeat this on another Win10 PC and I know about another BLE developer having the same issues.

I have been testing with the MSP430 USB-Debug-Interface MSP-FET430UIF and was not able to reproduce the issue. So I am not sure what exactly is causing the issue, if it is to a specific MSP-FET programmer that is causing the "crash" of the Nordic device on the Nordic desktop app. 
Might be that the issue is specific to the version MSP-FET that you are using, currently I have not been able to preproduce, this could also be a specific driver issue or a somewhat strange windows anomaly. 

Can you share what drivers for the TI MSP you have installed and what version the USB device you connect is?
