best ioT protocol for consumer products to send data to smartphone application

[Vidula]

Hi , We are developing a wifi enabled consumer iot product using esp32. There will be a temperature sensor connected to the eps32 for temperature measurements. The esp32 will be configured in station mode and connected to the local wifi router and there will be a smartphone application which should be able to read temperature value from the esp32 remotely.
We want to know for this application which ioT data protocol is best fit? Please suggest. Sorry but wifi protocol is new for me, I have expertise in ble.

Thanks in advance.

To give some more thoughts to this, I think you are going to have to give some more details on the requirements. For communications, as you mention, you have WiFi or BLE.

o Will your product be battery powered?
o Does your product HAVE to be connected to the Internet? i.e. is it acceptable to communicate with devices only in Bluetooth range?
o Does your product need to send data one a one-to-one basis or one-to-many?
o How often does your product need to transmit new data?
o What is the size of the data in a transmission?
o ... much more
