Sending high volumes of data through WI-FI

[Raluca]

Hello, 

I am trying to send data from a delta-sigma 32 bit ADC - the front-end is an EEG amplifier -  via WI-FI to my broker. I would like a recommendation related to the best way of sending the data. Taking into account the WI-FI Fundamentals course, I see three options: 

1. Through a broker 

2. Through the post action

3. I was wondering if it`s posible to use the nRF7002 DK as a WI-FI hotspot.

From these three options, which one would you recommend given the fact that there will be a huge ammount of samples?

Also, will it work better sending the data constantly or saving it in an array and sending it in a buffered way? 

Thank you for your time, I would appreciate any help! 

Warm regards, 

Raluca

Hello,

You can use any wanted protocol to send your data, that is up to you.  A common way if you require two-way communication is to use MQTT (this was shown in the fundementals course as well). It is hard to say what is 'best', if you want higher upload speed then you can eg. add more TX buffers.

This isn't possible unfortunately, as we cannot be a AP + STA simultaneously.
