No. It seems we have a new version that doesn't match the kernel. I 
found the following on the Manjaro site:

<quote>
     This is a firmware issue. The firmware needs to be downgraded to 
version 5 or you need to upgrade to kernel 4.19 and use the version 6 
firmware.

     Firmware Version Incompatibilities:

     The QCA9377 adapter will work on kernel 4.19 if the ath10k 
“firmware-6.bin” file is within the firmware folder.

     The QCA9377 adapter will work on kernel 4.14 if the ath10k 
“firmware-6.bin” is removed from the firmware folder.

     The firmware is located in:

     /lib/firmware/ath10k/QCA9377

     Delete the version 6 firmware and reboot if you have no internet 
connection (or need to remain on kernel 4.14). Otherwise upgrade to 
kernel 4.19.

The location on SL7.7 is /lib/firmware/ath10k/QCA9377/hw1.0/ and 
removing firmware-6.bin worked for me.
