BC127 Melody 7.2 -- RESET after call outgoing


#1

Hello,

I found a repeatable bug testing Melody 7.2.
When call is outgoing then bc127 resets inopportunely …

Please find below two sequences with UART RX/TX message (first show success and second shows the reset)

[UART TX] STATUS
[UART] STATE CONNECTED[1] CONNECTABLE[ON] DISCOVERABLE[OFF] BLE[IDLE]

Please can you investigate if you can repeat this issue and fix this ?

Thanks a lot,

@er1c,

I have tried the below and it did not reset. I did not change the volume before hand but it should not have made a difference.

SET HFP_CONFIG=OFF ON OFF OFF ON OFF
OK
write
OK

What phone did you have connected to the BC127 (iOS or Android)?

Hi @mlw

I tried again and get the reset once in three, calling my voice box using my LG G6 phone (android).

As you can see in the logs I use ROUTE command when I get the SCO_OPEN notification.
Does forcing ROUTE can cause such behaviour ?

Thanks for your help.

@mlw

I ran others tests and it seems that forcing ROUTE causes the RESET.
Can you double confirm this behavior ?

I use ROUTE command because when pairing with two devices (in that order :1st is Laptop and 2nd is Andoird phone) and streaming music from the Laptop then there is NO switch to the phone for outgoing call !!

[UART RX] CALL_OUTGOING 23
[UART RX] SCO_OPEN 23
[UART RX] AT 23 10 +CIEV: 1,0

But since, music continue streaming and I cannot hear the phone call.

Please advice,

Cheers,
Eric

Hi,

I hope you can help me on this issue !
Command ROUTE causes Melody to RESET.

When call is outgoing, SCO_OPEN 13 is received and command ROUTE 13 is sent.
Once in three, the module resets.

Please can you advice how to resolve that.
Thx

@er1c,

So just to be clear of the sequence so I am not chasing around trying to find it.

  1. Pair A2DP with a PC.
  2. Start streaming music from the PC to the unit so you can hear the audio coming out of the analog audio output.
  3. Pair with a phone which pairs the A2DP/AVRCP/HFP.
  4. Make a call with the phone (using AT commands through the BC127 or on the handset itself?).
  5. When the call is opened the SCO_OPEN 13 response is seen and the unit does not close down the streaming audio from the PC so the ROUTE command needs to be sent to be able to hear the call?

Regards

Matt

@mlw

Thanks for your time.

A) Firstly there is the reset issue:

When call is outgoing the module resets inopportunely as show in the following sequence:
[UART RX] SCO_OPEN 13
[UART TX] VOLUME 13 9
[UART TX] ROUTE 13
[UART RX] AT 13 10 +CIEV: 2,2
[UART RX] CALL_OUTGOING 13
[UART RX] OK

[UART RX] Ready

Please note that I force the “ROUTE” command when I receive “SCO_OPEN link_id”
It seems that forcing “ROUTE” in that cases causes the reset.
I didn’t have this issue with Melody 6.1.5: is there a change towards the use of the ROUTE command ?

B) On the other hand : I force the ROUTE command for couple reasons but the most important is because I get bad behavior with the following sequence:

  1. Pair with a PC (A2DP and HFP are open).
  2. Start streaming music (A2DP) from the PC to the unit so you can hear the audio coming out of the analog audio output.
  3. Pair with a phone which pairs the A2DP/AVRCP/HFP.
  4. Make a call with the phone (on the handset itself).
  5. The music continue streaming and I cannot hear the outgoing tone.
  6. When the call is opened the SCO_OPEN 13 response is seen (CALL_ACTIVE also) the unit doesn’t close the streaming audio from the PC but switch to the phone call. When CALL_END is received then I am unable to switch back to the PC audio stream (even when pushing PLAY/PAUSE on youtube) so the ROUTE command needs to be sent to be able to switch back.

Thanks a lot for your help !

Cheers,
Eric

Hi @mlw

A] Were you able to replicate the RESET issue ?
B] Do you have the same behaviour with the described connection scheme ?

Thanks for your help.

@er1c,

Cannot repeat the same behaviour on either 6.1.5 or 7.2 as per the below annotated log file.
