Any suggestions, how to fix this?

Thanks

I think you are missing the firmware package. Make sure you install the ct version of ath10 pacakges kmod-ath10k-ct as the device is low on memory:

ath10k-firmware-qca988x-ct - 2019-10-03-d622d160-1
kmod-ath - 4.14.180+4.19.120-1-1
kmod-ath10k-ct - 4.14.180+2019-09-09-5e8cd86f-1
