Attached is a Windows x64 and x86 application designed to simulate sending data from a PC to a smartphone. Configure your PC's Bluetooth LE to use port 1 to 5 and rename it to 'AEON'. You can then connect your phone to the 'AEON' SSID. Using the simulator you will be able to send data to your phone. If your computer does not have Bluetooth LE you must purchase a USB Bluetooth 4.0 HM-10 or BT-09 compatible adapter

Interesting, can you share your code for other users ?
I am glad to see that you are using the xGauges library.

Hello Klaus, don't you remember that xGauges library, you originally made it for me, thank you again.

Hi, Very nice presentation... But your code command structure is for DWIN LCD which are not android base so I think you adopted the same command structure for android app... am I right?

You also have some sample b4x code for receiving data from the interface to Android via Bluetooth. the hex addresses that follow are the commands transmitted from the interface to the meter or to the telephone.

Dear Mr. Blue Sky, it is possible to say without fear of contradiction that the dashboard presented is truly beautiful
And therefore with this writing, the entire B4x community (?!?!?) kindly asks you to make the necessary sources available to us to achieve the above
Most likely we will never use it, but it will be a pleasure for the eyes to see it running on your PC

a drawing is better than a long speech, it should help understanding

The objective of my approach is to provide efficient and easy-to-access tools to allow users to develop their own interfaces and dashboards for smartphones. I chose to use B4X for several key reasons:

Accessibility: B4X is designed to be accessible to developers of all levels, including beginners. It avoids the complexity of traditional development environments like Android Studio, making app creation more affordable for those without extensive programming training.

Cross-Platform Compatibility: B4X allows you to develop applications that work on both iOS and Android from a single code base. This simplifies the development process since you don't need to manage two separate projects for each platform.

Speed of development: Thanks to its numerous predefined tools and libraries, B4X considerably reduces the time required for development. Users can quickly create working prototypes and test them on their devices.

Customization: B4X provides sufficient flexibility to customize applications according to the specific needs of each user. Whether to control my box or integrate unique functionalities, B4X allows this adaptation without requiring in-depth technical expertise.

In summary, by offering B4X, within my subscribers and Facebook groups, my objective is to democratize the development of mobile applications linked to my interface, by making the technology more accessible and by giving users the freedom to create personalized solutions. adapted to their needs.

 

[thetrueman]

So now we have clear picture about what you are doing... Nice work and keep it up

Dear Mr Blue, since you insist on showing us all these delicacies, I am the spokesperson for the entire community to ask for the release of the code necessary to reproduce everything
In case of inserting other posts that make us dream without having the possibility of reproducing what is described, a petition will be requested to close this 3D Thanks and goodbye

Thank you for your appreciation, without B4X and Erel and many contributors none of this would have been possible. Making smartphone application development accessible to as many people as possible

So as many people contribute at B4X, it is nice if you share some demo codes having basic functionality not completed, which someone could learn. I also want to make a display for some sensors using same your idea i.e. embedded display and BLE app. Thanks.

Attached is a Windows x64 and x86 application designed to simulate sending data from a PC to a smartphone. Configure your PC's Bluetooth LE to use port 1 to 5 and rename it to 'AEON'. You can then connect your phone to the 'AEON' SSID. Using the simulator you will be able to send data to your phone. If your computer does not have Bluetooth LE you must purchase a USB Bluetooth 4.0 HM-10 or BT-09 compatible adapter
