I did three weight measurements: 136,5kg (0555 big endian) found in package no. 1393:

Bluetooth Attribute Protocol Opcode: Handle Value Notification (0x1b) 0... .... = Authentication Signature: False .0.. .... = Command: False ..01 1011 = Method: Handle Value Notification (0x1b) Handle: 0x0043 (Unknown: Unknown) [Service UUID: 352e300028e940b8a3616db4cca4147c] [UUID: 352e300128e940b8a3616db4cca4147c] Value: 090107e001090a331c055501dc019d

136,7kg (0557 big endian) not found - propably to similiar to the first measurement.

138,1kg (0565 big endian) found in package no. 7287:

There was no body composition data shown in the app, allthough the scale shows muscle, fat and water percentages.

I used DCODE to find timestamps in the values before and after the weight string. Some Hex 32bit formats show weird time stamps, like from the year 1907 or 2050, but I did not find the exact date (May 27th, 2019, 9:33 MESZ)

If needed I will add more data. Just let me know.

I redid the measurement to hopefully come up with more clear results. btsnoop_hci.log

I did manage to identify the age/sex/height data that is asked for by the app, a hex string with todays date (August 13th 2019) - both in combination with the hex string of the measured weight.

What I did not found were hex strings of fat, water and muscle which were measured at 36,1%, 45,3% and 34,5% through all three measurements.

oliexdev commented 5 years ago

could you make the values more clearly what is what? With the ^^^ marks is a bit difficult to read. Also please write down the true values for sex, age, measurement time and so on. Also would be great if you could do a measurement with a larger different.

What I did not found were hex strings of fat, water and muscle which were measured at 36,1%, 45,3% and 34,5% through all three measurements.

Maybe only the impedance value are transmitted and the calculation is done in the vendors app!?

value of package 996: 0c0101290000c5055102 values: 0c0101(unknown), 29(age 41), 00(sex? male), 00c5(height 197cm), 0551(weight 136,1kg), 02(unknown)

I'm not quit sure whether height is encoded in 4 digits (00c5) or only 2 digits (c5). If its encoded in two digits, the purpose/meaning of the other two is unknown.

value of package 1413: 090107e3080d090b00055111ff15dc values: 0901(unknown), 07e3(year 2019), 08(month 08), 0d(day 13), 09(hour 09), 0b(minutes 11), 00(seconds 00), 0551(weight 136,1kg), 11ff15dc(unknown)

Also would be great if you could do a measurement with a larger different.

Yeah, I will get a case of beer today and repeat the measurement :)

Maybe only the impedance value are transmitted and the calculation is done in the vendors app!?

Can those three values be derived from only one impedance value? In the packages with the timestamp, there are 8 unknown digits at the end of the value string which stay very much the same over the course of all measurements. Maybe the impedance or fat/water/muscle value is encoded there.

oliexdev commented 5 years ago

values: 0c0101(unknown), 29(age 41), 00(sex? male), 00c5(height 197cm), 0551(weight 136,1kg), 02(unknown)

you could easily check if the value 00 is male or female if you switch the sex in the vendors app and log again.

Yeah, I will get a case of beer today and repeat the measurement :)

But don't drink while your measuring :wink:

Yes combined with your sex, age, height you can calculate the other values, see for example YunmaiLib.java or OneByoneLib.java classes.

But the values can't be constant if you have different fat, water and so on values. So its good to have large different mesurements in the values / log files to identify the large differences in the hex values.

oliexdev commented 5 years ago

I added a first test implementation with commit https://github.com/oliexdev/openScale/commit/87b62ed6e2e30799eba17b70a0ffba54f47e574c please test it and post the log files with the branch dev version.

I looks like they are using the BLE weight standard profile, see https://www.bluetooth.com/specifications/gatt/characteristics

But on the first look they are transmitting the impedance value and do the calculation in the app itself.

@G0nzzzz are you a java developer?

G0nzzzz commented 5 years ago

Wow that was fast :) I'll give it a try on sunday and report back.

I've done some basic Java stuff, yeah.

oliexdev commented 5 years ago

@G0nzzzz I have some formula for the body fat, water and muscle but I need three different proper measurements from you with the following data to evaluate it:

please get those values from latest vendors app.

please get those values from latest vendors app.

I used the latest vendor app version available to me, which is Soehnle_Connect_5.1.2

G0nzzzz commented 5 years ago

@G0nzzzz I have some formula for the body fat, water and muscle but I need three different proper measurements from you with the following data to evaluate it

Or do you mean: three different measurements over the course of several days, without adding artificial weight?

oliexdev commented 5 years ago

can you double check you fat, water, muscle values? Did you weight yourself with barefoot? Because it can't be always the same values...

G0nzzzz commented 5 years ago

Propably it's the same value because I was not standing on the scale long enough to take a new body impedance measurement. Will do again.

oliexdev commented 5 years ago

@G0nzzzz thanks but the impedance measurements are the important information which I need now.

G0nzzzz commented 5 years ago

@oliexdev here are three new measurements with varying fat/water/muscle values (used female for sex):

Additionally I can confirm that sex was identified correctly, encoding is 00 for male, 01 for female. The corresponding hex value changed from 00 to 01 when I entered female as value for sex in the app.

oliexdev commented 5 years ago

@G0nzzzz thanks my formula works. the last bytes are the impedance values. I added in your comment the associated hex bvtes. Could you log the user creation process? Please delete for that every user in the vendor app and reset your scale. Then log the Bluetooth communication if you first time connect to the scale. Please write down which sex, age, height and weight activity level you choose for the creation.

G0nzzzz commented 5 years ago

@oliexdev I'm not at home during the weekend, but will do as soon as I'm back.

oliexdev commented 5 years ago

@G0nzzzz any updates?

G0nzzzz commented 5 years ago

@oliexdev I deleted all previous users and created a new one: Name: yoogiibaaeer Birthday: January, 1st, 1980 Sex: male Height: 197cm Activity Level: 2 Weight: 137,5kg

oliexdev commented 5 years ago

@G0nzzzz thanks please try out the latest soehnle dev branch and post the openScale log file. Before you test it please reset your scale (or delete all scale users), so that openScale need to create a new user for the scale.

G0nzzzz commented 5 years ago

Deleted the existing user with Soehnle app: btsnoop_hci-deleteuser.log

oliexdev commented 5 years ago

could you weight again and note down your weight, height, age, activityLevel, fat in percent, water in percent and muscle in percent. Need to check something.

Do you see something on the scale if the user was successful created on the scale?

G0nzzzz commented 5 years ago

@oliexdev User is created successfully, and displayed in the vendors app, but height is off (should be 197, is 50432), see screenshot. Additionally there is a warning about the timestamp of the measurement.

thanks the body height should be fixed in the latest dev build, please try it out.

Please also weight again and note down your weight, height, age, activityLevel, fat in percent, water in percent and muscle in percent and attach the openScale log file. I need to check if the hex values are transmitted.

G0nzzzz commented 5 years ago

Body height is corrected.

the attached log file looks very strange. They don't go to any steps. Could you double check it and do the logging again?

oliexdev commented 5 years ago

@G0nzzzz any updates?

G0nzzzz commented 4 years ago

@oliexdev

I've done the logging again, see attached file. I noticed two strange things: the bluetooth connection is unsuccessful as long as the location permissions aren't set/enabled. After enabling location permissions the bluetooth connection is successfully set up, but no values of measurements are transmitted to the app.

@G0nzzzz thanks could you test the latest dev branch version? It should work now.

G0nzzzz commented 4 years ago

@oliexdev Wight, BMI, water, muscle and fat values are transfered to the app now. BMR and TDEE are not displayed correctly:

G0nzzzz commented 4 years ago

Oh, and there seems to be an issue with the date. In the second last row of the screenshot you can see the year displayed as "58119"

oliexdev commented 4 years ago

@G0nzzzz thanks the TDEE and BMR are calculated with the official formula from wikipedia. Did the date problem happens every time? In the log file you have the correct time. It is a bit strange. Could you post a photo of your scale with the same camera angle like in our wiki gallery?

oliexdev commented 4 years ago

the date bug should be fixed now
