Ok I also tried to run windows XP in a virtual box, but even that one does not work. I was able to see the btr3 as an usb device, and install the driver. But when I run the wizard it cannot find the blue core model (/ in use by another software). I know a windows pc would fix this, but no...

Thanks for a quick reply. I tried different USB ports and also usb c directly ( I have a Macbook with only TB3/USB-c ports). These are the last (of many :wink:) lines after the dmesg command: IOBluetoothHostControllerUARTTransport::SendUART mProvider->enqueueData() failed error=0xe00002d7 ****...

Ok a while back in this thread I tried to update the btr3 with a Mac unsuccessfully. I tried again so I could copy my terminal screen. Here is what I've done, maybe anyone can shed some light: I'm on high Sierra Installed dfu util following this link http://macappstore.org/dfu-util/ Put BTR3...

Thanks for this! So I (successfully) installed the one for Macos: https://www.thesycon.de/eng/dfu_utility_macos.shtml.. But now I don't know what to do. I put my device in DFU mode, connect it to my Mac, run sudo dfu-util -l in terminal and it does not find my device, it just states the...

Please add firmware update support for OSX! I don't have access to windows computers.

I have exactly the same problem with my Avantree Priva III (except for the distortion). It works fine with the BTR3 but the BTR1K does not. It might be the chipset (i read somewhere on amazon that avantree recommends csr shipset which is the one in the btr3), although i don't know why the...
