Hi Abhishek, I want to ask you some questions about your patch: Bluetooth: Handle BR/EDR devices during suspend. (https://patchwork.kernel.org/project/bluetooth/patch/20200311085359.RFC.v6.2.Icc7c35e1cabf10f8a383a009694987520f1d1b35@changeid/) Platform: L5.10 + Bluez5.55 + Marvell BT chip Background: Our test team usually try suspend/resume test when transferring large file through BT, to see if the file transfer can be continued after suspend/resume. It can works well before L5.10 But we found on L5.10, the BT connection lost if we try to suspend/resume, so the file transfer(through OBEX Object Push) shows failed. Then we found your patches when debugging. Questions: 1. Before L5.10, kernel always keep BT connected during suspend/resume. So why we need to disconnect all the BT devices when system suspend now? 2. I found that the device been disconnected due to suspend won't been auto-connected after resume, shouldn't we get the BT device auto-connected after resume like wifi devices done? 3. For the large file transfer, if the BT been disconnected during suspend, the transfer will fail, do we have any methods to avoid this issue? I'm new to Bluetooth, there are many things I don't understand, looking forward to your answer, and thanks for now! Best regards Sherry sun
