asking if esp32 can waked up by mqtt or ble write from phone.

I 'm now into deep sleep mode in esp32.
there are 3 ways of wake up esp32
1. by timer
2. by gpio pin
3. by coprocessor.

if user give signal to module by mqtt or ble write from phone,
I wonder if esp32 module can be waked up.
I think..by mqtt...it's impossible because to use mqtt, internet should be connected but if processor is in sleep mode, can't get mqtt topic.
but...ble signal from phone...maybe possible solution?

Its exactly the same case. In deep sleep radio is not active, so no wifi nor ble communication.
