Displaying values having fast update rate in ESP8266

Hi,
I'm working on a project, there I'm having three kinds of values :

  1. A float values which is updating every 20 seconds.
  2. Another float value which is also updating every 20 seconds.
  3. A integer value which is updating at least 10 times a seconds (its a sensor value ranging from 0 to 1024)
    I'm displaying those values in the IOT cloud platform as:

please ignore the inaccuracy in the SpO2 value :smiley:
as you can see I'm intending to plot that higher frequency value on a graph, the problem is the delay.

I've tried the Firebase before to get these three values, and now this. The IOT cloud is better in the realtime values but still it is having a delay in the order in several seconds, typically 5 to 10 seconds.

Please suggest me a way by which I can display these three values altogether with lesser delay.

Context

I've one ESP8266, 1 HC-05 module. so both wifi and bluetooth modes can be done.

I'me thinking of a option

  • an offline local connection can be established and simply by wifi or bluetooth, but I dont know any app development for that.

if anyone knows the solution of this problem, please feel free to reply.
Thanks.

BBLYNK really isn’t the right tool for what you want tondo., due to the latency and congestion of the data path.

There may be several other methods, but there will be better informed types than myself who will suggest specific ideas.

How far is your user going to be from the data source ?

not more than 2 meters.

The project of pulse oximeter, so the person will put the probe in the finger and and through the ESP board he/she will get the values in the mobile.
