I need to make radio remote control with this needed specs:

1. The remote controller should be light, small and low battery consumption
2. The range is not much important. Anything between 50-150 meters is OK
3. Receiver can be ON all the time
4. Transmitter should be sleeping if no key is depressed
5. Wake up and transmission should be completed under 100ms max.

Can the Bluetooth Low energy modules talk to each other?

or

Can the WiFi modules like ESP12 etc talk to each other like an RF tranceiver?

And if these are in sleep mode, how fast can wake up and complete a transmission?

Thanks,
Ioannis
