BLEtool x750 Openwrt 19.0.7

Has anyone had bletool working on a standard version of OpenWRT 19.07.

I have got bletool able to run by creating a symlink of libjson-c.so.5 with the below once that is done I can run bletool.
ln -s /usr/lib/libjson-c.so.5 /usr/lib/libjson-c.so.2

Now when I run bletool enable i get:
root@OpenWrt:~# bletool enable
ubus_lookup_id failed.
Invoke Error

Anyone had any luck?

Seems ubus service is not up running.

Not sure if ble tool is working in the snapshot, which is 1907 now.

Thanks for the feedback.

Getting the same issue on the snapshot.
