At the moment there are two separate applications:
- one serving as a „display” – >> MPe BT – ENGLISH VERSION
*Compatible with MPe mainboard firmware from version v6.008. Go to the archive.
- second one used for settings – >> MPe SET – ENGLISH VERSION

For whom it's this APP?
The MPe computer has the ability to communicate via a MPeBT module with a smartphone (Android OS).
- Thanks to this connection, we can display data, such as speed or range, on the screen of our smartphone.
- In addition, we have configuration options transferred to the phone, because everything can be set both from the display on the handlebar and from the MPeSET application.
- It is also possible to add buttons to your electric vehicle. Then we can completely operate without any display on the handlebar and control the MPe computer with these buttons.
- The buttons on the handlebar may also facilitate the use of the system, e.g. while wearing contactless gloves.
At the moment only Android OS is supported.
INFORMAION: the MPeBT module does not work in cooperation with the MaxiColor 850C display.
About MPeBT module
The whole is based on the popular HC-05 module. To facilitate cooperation, I designed a special adapter, i.e. a tiny PCB, which we connect to the MPeBT module, and then plug it into the motherboard. The resulting “bumps” are filled with 3D printing, and finally wrapped in a heat shrink.
Installation process
The applications are available for download in * .apk format.
To download such an application to your phone:
- download it directly to the smartphone’s memory or copy it from a computer using a USB cable.
- Then run the downloaded file and follow the instructions on the screen.
- By default, Android has blocked the ability to upload such applications for fear of viruses. To unlock it, go to the phone settings and activate the “Allow app installation from sources other than Google Play Store” tab in the security tab.
- When pairing the phone with MPe, you will be asked to enter the password. Then enter the password, which is four digits: 1234
And now a treat for DIYers 😀
Both applications were created on the free MIT APP Inventor website available at: http://appinventor.mit.edu
I encourage you to download the MPeBT application project and develop the project together! 😊
Thanks to this you can create an application tailored to your needs.
If you do this, be sure to show off the effects, SEND a project or screenshot to me and I will put it on my blog to make it available to others.
What data does MPe send over BT?
The MPe computer cyclically sends a data packet via MPeBT module to an Android application.
Currently, the data packet has the csv format: “MPe; 1; 2; 3; 4; 5; 6; 7; 9; 9; 10; 11; 12; 13; 14; 15; 16; 17; 18; 19; 20; 21; 22; 23; 24 “where:
- Speed
- Distance to go
- Battery charge percentage
- Daily distance
- Instant power
- Temperature 1 (e.g. motor)
- Assist mode
- Total distance
- Average speed
- Maximum speed
- Moving time
- Battery voltage
- Instant Current
- Maximum current
- Maximum power
- Energy consumption per kilometer
- Battery capacity
- Current battery consumption (Ah)
- Temperature 2 (e.g. controller)
- Number of charging cycles
- Is the brake active
- Is the cruise control active
- Software version
- Is road mode active
The MPeBT smartphone application simply “cuts” this data in place of a semicolon and inserts it into individual fields on the screen.
