acquarius.13 Posted December 12, 2019 Share Posted December 12, 2019 Hi everyone, I apologize about opening this new topic. As I wrote on the subject, I'm still suffering bluetooth issues: it might be available, but it isn't able to connect to anything. Most of the time it doesn't switch it on at all: the icon on the topbar is shaded grey but in system preferences it appears active, even if it doesn't work at all. I also tried to patch the SSDT for UsbInjectAll.kext, with no success. I tried to properly modify the USBPorts-E7450.kext, with no success. I'm still not so good in doing these things..can you please help me? I manually saved the ioregistry file because the install_tool.sh wasn't able to do by itself.

Moderators Jake Lo Posted December 12, 2019 Moderators Share Posted December 12, 2019 Not an USB issue since it's detectable. Try updating kexts with this new version https://github.com/acidanthera/BrcmPatchRAM/releases Link to comment Share on other sites More sharing options...
acquarius.13 Posted December 12, 2019 Author Share Posted December 12, 2019 Thanks Jake. I will retry again but previously I had the same issue with 2.5.0 of BrcmPatchRAM. I can try again and I will let you know. But I suppose I will have the same problem Link to comment Share on other sites More sharing options...
acquarius.13 Posted December 13, 2019 Author Share Posted December 13, 2019 I confirm I have installed the latest version of BrcmPatchRAM (2.5.0) before posting here. So the issue appear with the latest version, but I'm pretty sure I have it also with 2.3.0d3. Might it be a problem of virtualSMC? many thanks edit: a partial solution occurred putting the machine to sleep (by closing the lid) and leaving it there for a few minutes. After waking up, bluetooth is working correctly. Do you have any possible hint? Thanks again Link to comment Share on other sites More sharing options...
acquarius.13 Posted December 13, 2019 Author Share Posted December 13, 2019 I don't want to talk too loud..but after updating to 10.15.2 the configuration seems to be working.. Is that correct to keep the SSDT-UIAC.aml (with proper USB configuration) and UsbInjectAll.kext (this one in /L/E)? If so, and if you agree, I might share my EFI folder with the community in a new git repo. When still on 10.15.1 I tried deleting virtualSMC (and SMCBatteryManager) and replace it with FakeSMC (and ACPIBatteryManager) but bluetooth was not working..

acquarius.13 Posted December 13, 2019 Author Share Posted December 13, 2019 Obviously I talked too early: after a couple of reboots bluetooth is still not working. I don't know what to do to solve it. Please give me an hand Thanks a lot Link to comment Share on other sites More sharing options...
pafkata Posted December 15, 2019 Share Posted December 15, 2019 I am unable to get BT working on 10.15.2 . I have E7240 with DW1550, which is essentially the same chip as DW1560. I have the feeling that it's something USB power related as BT device is detected, but unable to connect to anything. Link to comment Share on other sites More sharing options...
acquarius.13 Posted December 16, 2019 Author Share Posted December 16, 2019 I tried an hard method: formatting anything and perform a clean install of Catalina 10.15.2. Result: no way. I suspect it can be a usb wrong configuration too: I tried to add the HP13 to usb20internalhub (which appears in IOregistryexplorer when I close/open the lid) in USB-E7450.kext through PlistEdit Pro (pic attached) but it’s again useless, probably because I wrote it in a wrong way. @Jake Lo can you please have a check? thanks Ps: if the problem is with no solution, I suspect I will have to downgrade to Mojave edit: in order to be clear enough, I just want to underline that bluetooth works only if I close/open the lid (waiting for the hack going to sleep). But at the first boot (or reboot) it doesn't work. Link to comment Share on other sites More sharing options...

acquarius.13 Posted December 16, 2019 Author Share Posted December 16, 2019 Dear @Hervé, I apologize for the wrong orientation of that pic. I will for to rotate it in the proper way next time. Please consider that my E7450 has been formatted and I still don't have my password manager installed there. Without it, I cannot login to the forum. So I apologize again. Do you have any hint about our issue? I mean, mine and @pafkata? Link to comment Share on other sites More sharing options...
