Need help reading the memory of an OMRON BP7250 Blood Pressure Monitor

Using Arduino General Electronics
1

Hello all,

Does anyone know how to read the blood pressure readings stored at the memory of an OMRON BP7250. I did google on each letters and numbers written at some of the chips onboard but I didn't seem to find anything relevant

Any help will be appreciated:)

Attached above is the board of the blood pressure monitor

I'm really new to this sort of stuff sorry in advance

Edit:
I want to transfer the values stored on the memory to my Arduino

It should display them on the included screen. It will be in the user manual

Welcome to the forum

What I'm looking for is how can I get those values and transfer those data to my Arduino. Sorry for not clearing things up. Is there any way to achieve that?

I think you are leaving out lots of information on your project. Answers are unlikely to be what you want until you clearly explain what you want.

You could find out what the display is and replace it with your arduino. If you know what the display is then you should be able to reverse engineer what signal = 1 for example.

Or you could use pattern recognition of the display to generate a signal for your arduino.

Or someone can enter the information into the arduino using serial

It all seems a bit of an odd thing to do. What is the purpose?

Well generally, I want to get the readings history stored in the memory and use those data to create an application

None the wiser. If you want the readings stored in history then use the omron to display them and then manually enter them through serial monitor into variables stored in your arduino.

This meets your stated requirements

Presuming this is not what you want so state the requirements more accurately

Sorry, but I think you have no chance to read something from this chip if it does not provide data exchange with a computer

Try to solve the problem in a different way

Most likely, the history information is stored in the nonvolatile memory of a proprietary microprocessor, and is simply not accessible by amateurs.

According to the manual the BP7250 blood pressure monitor has Bluetooth, and Omron have a free App for your smart device.
