BLuetooth speaker in crash

[donny681]

I don't know why the esp32 bluetooth speaker must be in crash when the module get audio data over 15500 .The ESP32 break down .Can you show me your menuconfig about ESP32-specific and Bluetooth ?

I see the same problem but always after 700 packets. I'm playing audio from either my iphone 5S or my 11" macbook air

Got crash logs? The screenshot cut off the interesting parts.

[akohlsmith]

Yes, I lost them when my computer crashed but will upload them tonight. There doesn't appear to be anything super interesting but I'm still a newb at the ESP32-side of things.

I wonder if this is related to #14...

Well it's not exactly a crash log, but it's all that comes out from the serial console:

Sometimes (but not always) several seconds after this last message about the 700th packet, I will get additional output:

At that point, the laptop (in this example) disconnects.

Hmm. That smells like an issue in the underlying BT software stack, and I don't have the expertise to interpret those messages.
