#Drivers for bluetooth csr 4.0 dongle Patch
december 2020: Since I haven't had time for months to work on a patch for the linux kernel please feel free to post your findings on the bug page mentioned right above and contact the kernel maintainers thereafter if everything goes well.Īnyone who would like kernel support please test this patch and write back with your results in the comments. And then I will post our findings here: and then lastly contact the kernel maintainers (and try to comply with the 'Tips for patch submitters' ) We need to contact the linux kernel maintainers for bluetooth support, but before we do that we need more people than me to confirm that it works. So the dongle is using a fake CSR chip made by Barrot as previously mentioned. It was possible to make a patch that makes the dongle work in Linux, but we have some work to do before we get it into the kernel. LMP Subversions currently unknown for products 1 and 2 below.

It works fine in Windows 10, but not in Ubuntu 18.04 (also not with kernel 5.3). After the patch you wont see the event/command in the output of hcidump. You will only see the last HCI Event for Error: Unsupported Feature or Parameter Value as long as you have not applied the patch. > HCI Event: Command Complete (0x0e) plen 6ĭelete Stored Link Key (0x03|0x0012) ncmd 1Įrror: Unsupported Feature or Parameter Value Manufacturer: Cambridge Silicon Radio (10) LMP Version: 4.0 (0圆) LMP Subversion: 0x1113
