NodeMCU based data retrieval form ihealth pulse oximeter

Hey, im currently working on a project where we are using a pulse oximeter to read the patients pulse rate and store this to the cloud server using NodeMCU . For now we are using the ihealth AIR pulse oximeter device to get the data... we are trying to get the data from pulse oximeter using Nodemcu but we dont now how to do that and we also dont know is that possible or not so plz suggest some method to do so ?

Im using this device (in link): https://ihealthlabs.com/fitness-devices/wireless-pulse-oximeter/

Yes wzaggle sir we using android app to get the pulse oximeter data till now..

This isnt clear to me.

1.) What is this: "pulse oximeter" you have not provided a link to it.. nor the datasheet. 2.) You state you are currently using this device: "ihealth AIR pulse oximeter" to get reads/data... but you have not provided a link to it.. nor a datasheet. How is this getting you a reading? Physical connection? Cloud/wifi/bluetooth connection?

Without you posting some more details.. or at least helping us know what it is you have in front of you.. nobody is going to be able to help you unfortunately.

I suspect this unit, like other commercial units, requires a BLE login credential that the company is not going to share with you. You can always write to them and ask if it is indeed secured. You can also get a BLE shield of some sort and see what you can "discover" from trying to connect to the device over Bluetooth. It may be open broadcasting its data but I wouldn't count on it.

You can get plenty of Oximeter circuits that work wired with Arduino, but don't come with pretty cases and finger clips. You could always design and print one with a 3D printer and there might even be some files for these already being shared on DIY sites.

What does the pulse oximeter user manual say about the data communication? Mine has no wireless feature.

If it is not wireless then it might have docs for the protocol. Or it might also be secured. You would need the technical manual for the interface, maybe I2C or SPI. I assumed you were getting data now from the IOS or Android App via BLE.

I found just this information about the device.

Yes I found that and it said "wireless". There is also an API but I have not read through the link.

Then you know where you have to start learning, for your project :-]

Sorry... Not my project. I would start with an ESP32 and see if it was advertising any services. Check the reading on the device and see if it matched with any of the BLE data. But that's me. Too many other projects on the plate at the moment. I do wish the OP all the best of luck however. :)
