Yup, can confirm.
I tried unpairing all and repair in different order (various combinations), same thing.
If I put HA in flight mode, as it said it kills the BT (both normal and LE), however it also kills roger connection. That part I couldn’t find (what happens with roger direct in flight mode), but my tests show it behaves like that.
All connections are dead. Or in other words, same chip handles BT and roger connection (or at least, same power supply), that explains why they could put both of them in the same aid.
The moment pen enables BT, HA goes nuts.
This was on automatic roger program.
I’ll try with manual and report here if there’s any difference.
Edit: report - same thing. They just kill each other the moment I want to use mic program, and of course, switch back to autosense.
So, my conclusion is that no BT feature of regular pen 1.1 can be used with marvels, because they go crazy. They seem a bit better when both HA and pen are unpaired from phone (just few pings and then stop, but it’s because pen is searching for BT device), and the moment you pair ONLY pen with your phone, HA goes crazy, even if neither BT nor LE_BT from HA is officially connected to the phone.
So basically if you have Marvels and choose regular pen, DO NOT TOUCH phone call buttons since they activate the BT
Next idea would be to test proper BT mic, but I don’t have it, so someone else could try that, but I doubt it works because of what follows.
HA refuse to receive audio signal from call when it’s put into ‘audio only’, they only receive call sound when put to ‘call and audio’, but in that case they also steal the mic. Tested using skype echo assistant.
Only way that comes to my mind to split those two would be to use Y splitter audio+mic, then connect BT emitter to audio, connect HA onto that if they will obey*, and on the mic side again BT emitter to connect BT mic.
Regarding * - if you put roger select in place of that BT emitter it will work properly - redirect audio to the HA, with additional benefit of not using BT which I think uses more power than roger tech. Don’t hold me on my word about that though.
My phone (S8) can split the audio signal, but not for calls. It has to do with that tech explanation I’ve omitted earlier (even though phones allow to fork audio BT signal, since phones can’t process two mic inputs, they don’t even try, even though you might not plugin mic thing on one side of that fork - I don’t if new ASHA or whatever BT protocol is named brings changes in that area as well)
@Cologne maybe this above answers some of your questions.
If I forgot to test something and I have correct / enough gadgets, please let me know and I’ll try.
On the bright side, now I know how exactly flight mode works, and I might start using that as my default until I want BT/roger connection.
