How To check these functionalities for hotspot?

[PraveenkumarDonga]

Hi!
Actually I created a hotspot manually!
So I want to test all these functionalities with that access point (hot-spot).
I want to enable and disable the hotspot using first two function.
hostapd.enable(interface,callback)
hostapd.disable(interface, callback)

could you please help me with this.
I tried but they are not working.

OS: ubuntu16.04
node -v:6.10.2,
npm -v: 3.10.10

Thanks,
Praveen
