<span style="color: rgb(32,33,36);">手机端有尝试发送停止响铃的cmd 给耳机端，</span>
|
||
|
||
但是因为我们耳机端没有发credit给手机，
|
||
|
||
导致手机端认为耳机端没有剩余的credit了，
|
||
|
||
进而手机端没办法发送停止响铃的cmd到耳机端，

|
||
|
||
however in phone's hci log, 11：28：27 we do not see mute right cmd
|
||
|
||
it seems that after 11:28:22.960783, FP cannot send any message via L2CAP.
|
||
|
||
<span style="color: rgb(23,43,77);">LE L2cap channel is not disconnected in the log. </span>
|
||
|
||
<span style="color: rgb(23,43,77);">Can you help to see why the PSM cannot be found? thanks</span>

Hey Danni,
|
||
|
||
I filter the HCI with btl2cap.psm == 0x0080, Seeker can receive the battery info from the L2cap event stream,
|
||
|
||
but the problem here is Seeker cannot send message to the Provider.
|
||
|
||
\
|
||
It looks like a similar issue (google internal ticket: <a href="https://issuetracker.google.com/issues/158958522#comment12" class="external-link" rel="nofollow">b/158958522#comment12</a>) when we worked with realtek on ringing through RFCOMM.

Could you help to see if the issue can be fixed when Provider handles the credit correctly?
|
||
|

Thanks!
