I have a laptop Dell Inspiron 5770 with wifi QCA9377 and bluetooth Qualcomm Atheros.
Some details:
# lsusb
Bus 001 Device 004: ID 0cf3:e009 Qualcomm Atheros Communications
# lshw -class network

vendor: Qualcomm Atheros
physical id: 0

resources: irq:131 memory:d2000000-d21fffff
When wifi work alone without blueetooth I can stay connected also 20 hours without problem, but when bluetooth is active and transmit data with headphones, sometimes wifi disconnects, this happens also 3 or 4 times in 3 hours.
For intel wireless module and for ath9 I see parameter btcoexist, but this parameter doesn't exit for ath10k_pci or ath10k_core.
Is there a solution? If I need to open a bugreport, I'm unable to determine which package my bug report should
be filed against, could you help me?
Thank you
Giovanni
