The source : Samsung galaxy s6 with android 7.0
Like that it’s ok, I have ad2p and avrcp set up.
But when connecting the sink part with a bc127 source, then I have tws set up.
The config of the source bc127 is the same as the sink part exept for the profiles : 0 0 0 1 1 0 0 0 0 0 0 0
Just re read the posting, the link between the phone and the BC127 will be A2DP, the link between the two BC127’s will be TWS as shown in the diagram at the below link.
Yes I understand that with a phone as source and 2 bc127 sharing sink, it’s tws protocol.
My goal is to have a bc127 as source and another bc127 as sink without phone.
…
Ok I get it. It was du to the paired device list in memory. So it activates tws automatically even if no phone was connected or with tws_config off.
I cleared paired device list and now it’s ok I have ad2p protocol between both bc127.
But… I get back to a previous issue, by pio on sink part I can pause stream but can’t play…
I tried with 4 differents bc127 modules bought on 2 differents times, so it would be not a hardware issue…
I can’t figure it out…
I tested all pio, I can go forward, backward, vol +, vol -, pause but not play.
The strange thing is that pio for pause and play is the same, so it should make more sense if I couldn’t make both, play and pause.
It looks like the software doesn’t accept only the command play. If I pair the sink part with my phone I can play and pause.
It’s only when it’s paired with a bc127 source that I can only pause.
With your two modules, are you able to pause then play from the sink part?
Ok so its only the play command, I can only get forward/backward to work for some reason I have asked a colleague to have a go as well to check his results.
Is there any news about the play command issue?
I’m really stuck with that.
I can work with the 6.0.54 firmware version but it’s very unstable.
Will there be a new firmware soon with the play command corrected?
An other thing could do the trick, it’s to implemente the “a2dp play on connect” feature.
There is a build due out end of Feb (at the moment) which does have this specifically fixed. I have tested the test build and the play/pause PIO does work which it did not before.
