Hello,
I have Brymen 869s and brymen usb dongle BC-86X
I struggling to get the communication up and running in Python or C++, as wel as on Linux or Windows platform

My question are.
1. Can I find software example for communication with BC-86X /BM869s
2. I run to to following problems   - BC-86X  is represent as USB HID . There is only one USB Output endpoint. How can I send command to this HID device if there is Output endpoint
3. As far as I undersood  - protocol requires to send <0x00 , 0x00,0x86,0x66 > device returns the BM869s Display status encoded in 27 bytes - Do I make  correct assumption?

I have attached the protocol description

Thanks in advance
Miro

I start searching on this 93 pages blog but I haven't found it yet. Can you show me an example code reading the RAW data. snapshot from 3...10 line code should be sufficient
Are you using this library - https://github.com/libusb/hidapi

If you run TC in debug mode it will list the bytes used for communication.
