Luckily, we don't need to change anything because we can use the same pins as for the HC-05. For the HM-10 configuration we can also use the same Arduino sketch and parameters like in the chapter [Connecting a HC-05 Bluetooth module](https://github.com/oliexdev/openScale/wiki/Custom-Bluetooth-Scale/_edit#connecting-a-hc-05-bluetooth-module-to-a-tablet) (only change "both NL & CR" back to "no line ending"). It is even slightly easier because we don't have to pull high a KEY pin anymore. You can find the AT commands in the [HM-10 manual](https://github.com/oliexdev/openScale/blob/master/doc/custom_scale/hm_10/HM_10_Manual.pdf). For example to change the Bluetooth device name to `openScale` send the AT command `AT+NAMEopenScale` to the HM-10 module.

My first intention was to buy a ready to use wireless scale. So I searched on the internet for a wireless bathroom scale that can track my weight and display my diet progress on a smartphone or tablet. I found a couple of start-ups and companies which have wireless scales, for example [FitBit Aria](http://www.fitbit.com/de/aria) , [Withings Smart Body Analyzer](http://www.withings.com/de/smart-body-analyzer.html) , [Runstatic libra](https://www.runtastic.com/shop/de/runtastic-libra-scale) , [Medisana BS-430](http://www.medisana.de/Gesundheitskontrolle/Personenwaagen/BS-430-connect-Koerperanalysewaage-HausMed.html) and [Beurer BF-800](http://www.beurer.com/web/en/products/weight/diagnostic_scales/BF-800-white). Most of the design of the wireless scales and the app design are really good but the big drawback is that (except the Beurer BF-800 scale) sends all your data directly into the cloud of each company. Beside that you lost your privacy and the high prices of the scales, you need always an internet connection. You are heavily dependent to the company servers. For example some Withings users reported that they have always a delay between weighting and seeing the result in the app. All in all I don't want to give any health data to a company. The Beurer BF-800 was the only scale that doesn't send automatically all your data to a cloud (of course it's possible with Beurer-Connect). I decided to give Beurer BF-800 a try, so I bought one. I installed the [Beurer Health Manager](https://play.google.com/store/apps/details?id=com.beurer.connect.healthmanager) on my Nexus 10 tablet and tried to connect the scale via Bluetooth with my tablet. It didn't work. My tablet has Bluetooth 3.0 and the scale works with Bluetooth 4.0 (also named as Bluetooth Smart) and it is not downwards compatible (didn't know that before). To be fair on the Beurer website is a [list of compatible smartphones](http://www.beurer.com/web/we-dokumente/gebrauchsanweisungen/list-compatible-smartphones.pdf). But the Beurer Health Manager lacks also in design and many users reported on Google Play that they are unsatisfied with the app. Furthermore I don't want to buy extra a new tablet or smartphone that has Bluetooth 4.0 for only logging my weight.

Frustrated about the available commercial scales and the idea to have a new little project, I decided to make my own wireless bathroom scale. First of all I searched for information of similar projects. The resources that I have found are [SdCardBathroomScale](http://code.google.com/p/casainho-projects/wiki/SdCardBathroomScale) , [SmartScale](http://code.google.com/p/casainho-projects/wiki/SmartScale), [Bluetooth wireless bathroom scale](http://www.keyboardmods.com/2010/05/bluetooth-wireless-bathroom-scale-with.html), [hacking a digital bathroom scale](http://scanlime.org/2010/01/hacking-a-digital-bathroom-scale/) and the book [Arduino and Kinect Projects](http://www.apress.com/9781430241676). Both projects SdCardBathroomScale and SmartScale by casainho are really good. I wanted something similar. My goal was to have an appealing wireless scale that works with Bluetooth 3.0. All modifications of the scale should be hidden, so it appears like a normal scale. Also the constant connection to a Bluetooth device should not be required for the scale. Measured values should be temporary stored in the scale. Only if a Bluetooth device is around the scale, new measured values would transferred. Of course the power consumption of the scale and the microcontroller should be low as possible. Furthermore all data should be locally stored in the app or on the scale itself, so that the user has full control of their data. The app design should be light and simple. In addition I wanted to learn how to write an Android app from scratch. To fulfil all my requirements the project "openScale" was born.

I don't own every scale. But openScale is open source and lives from the open source community if you want to help you could try to reverse engineer your scale by analysing the Bluetooth 4.x protocol between your scale and the original vendor app, see [Bluetooth 4.x Reverse Engineer tutorial](https://github.com/oliexdev/openScale/wiki/How-to-reverse-engineer-a-Bluetooth-4.x-scale) for further information. If you understand the protocol then it is not complicated to implement it into openScale. I don't own every scale.

Personally I don't want to synchronise any health data to a company for privacy reasons. Therefore, openScale doesn't send any data to a cloud and not having permission to access the internet is a strong guarantee of that. Additionally, most of the used licenses by the cloud companies are incompatible with the GPLv3 license. So openScale won't support it directly but every user are free to do it anyway, just (auto) export your data and do whatever you like, see for example the [Autosync with Nextcloud tutorial](https://github.com/oliexdev/openScale/wiki/Autosync-with-Nextcloud).

The answer is simple because the Android API >= 6.0 needs access to the coarse location to search for Bluetooth devices. The App openScale doesn't read your location at any time. Read the official [Android Bluetooth Developer Guide](https://developer.android.com/guide/topics/connectivity/bluetooth-le.html#permissions) or read the [Android 6.0 Changelog](https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-hardware-id) for a more technical description.
