Reading data from Omron blood pressure monitor

Other Hardware General Electronics

I'm not sure why everyone was so rude to clarence6671 who posted a question on this topic in September 22. I have the same requirement. My monitor is an M7 Intelli IT. Yes, it is true that Omron have an app to read the data but it is far from complete. For example, it will only read the data for ONE of the users set up for this monitor. The monitor can accumulate data for two users, and I need to get the data for both. Also it requires to upload the data to their cloud service. I don't want this. I just want the readings on my own computer. Also it is very easy to make a measurement with the user switch in the wrong position, which means that either my readings are all mixed up with those of the second user, or the second user's readings are all mixed up with mine. I want the ability to correct this mistake if it is made, i.e. to move a reading from one user to the other. Omron do not seem to have provided a facility to do this. Since OMRON's app can read the readings from the montior via bluetooth, this is OBVIOUSLY technically possible. I'm just asking whether anyone has reverse engineered the protocol that they use, so that my software can do the same thing. Is this such an unreasonable request?

Thank you - Rowan

IKR?

If you have Wireshark (nee Ethereal), you can trap all the data being transferred. I would also pursue Omron, as they have all the intellectual rights, and know exactly how to defeat their built-in requirements.

No, it is not. I read your reference.

I would start by getting an arduino with bluetooth to connect and output some data, any data.

Get the Omron app and see if you can get some information from it.

Or the hard way: get one of the Logic analyzers on eBay like this one logic analyzer

You then have to decode the data.
