Collecting data from bluetooth device

We need to collect data from our bluetooth connected device. how can I do that? Can i write a code within the appsheet? an API to other app? please advice

What kinda device is this? Can you please elaborate bit more?

an electric sensor that operate simillar to the heart rate monitor 2A37
need to record the bit 2A37-000E

Does this sensor somehow generate data to a spreadsheet or dump data to a spreadsheet via IoT?

I also want something similar. I have a bluetooth weigh scale device. I have an app which gets the data from the connected bluetooth scale and show and record in an android app. I want to develop a custom app with this feature.
Please help if you guys can.
