sky979 Posted July 3, 2019 Share Posted July 3, 2019 Bluetooth version to be updated to v7-c5083 to be stable, and the distance can be connected far apart, v7-c4688 and c5799 distance and stability is not good Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 3, 2019 Administrators Share Posted July 3, 2019 Where did you find this other version c5083? Or is it just a typo and you meant version c5803 which I posted a few days ago? Link to comment Share on other sites More sharing options...

wl_michael Posted July 3, 2019 Share Posted July 3, 2019 Hello @Hervé, You did something wrong with the ZHX file. Use the nativ HEX File and Firmware will load up. Attached files with v5803. But for me still working only sometimes. Attached BT injector works with the base OSX firmware. But I have the same problems. BT Injector is for Mojave and Catalina.

matey Posted July 3, 2019 Share Posted July 3, 2019 I got Bluetooth working with my DW1820A 1028:0021, no disconnection and good sound quality tried for a long period of time. The main problem i still have is that my WiFi card just disappears from the system after about 10 minutes. Need to restart the whole system then its ok for the next 10 minutes. Any suggestions?

Administrators Hervé Posted July 3, 2019 Administrators Share Posted July 3, 2019 @wl_michael, quite possible I did something wrong; wouldn't be the 1st time... I simply Gzip'ed the extracted .hex firmware file but, yes, Rehabman's instructions clearly stipulate that the uncompressed firmware can load too. I looked at your files and I see the same 6KB .zhx compressed file I posted. I don't see any uncompressed file in there... Anyway, I've reverted to uncompressed firmware files and the version I seek to load now shows Ok in SysInfo: With regards, to the 2nd firmware file I had found and uploaded, it may not actually be a more recent firmware: even though the extracted file bears a name ending with "xxxx.0221.4688" when the previous one bears a name ending with "xxxx.0095.1707", once I load it, SysInfo displays version v7 c4688. So, who knows? Link to comment Share on other sites More sharing options...
