We're developing a product which contains an Arduino Nano 33 BLE (). We're using an original Arduino board, not a copy. We want to be able to establish a link so the product can communicate with an Android tablet. This is something new for us, so it'll save us a lot of time if someone can build an example for us.. which is this project. The example should include a simple app for an Android tablet and a corresponding app for the Arduino. The Android app should include a simple user interface including - a button to establish a connection to the Arduino or disconnect from it. - a text box where the tablet user can enter a string to send. - a "send" button which sends the string to the Arduino. - a received string box where a string send

Hi Jitendra S., I noticed your profile and would like to offer you my project. We can discuss any details over chat about android bluetooth.
It is an application where a user can select one type of event among several or a generic event to which they can add images, audio...or another technology that competes with them on price and effectiveness. The application must consider that a group of users update their location in real time with the lowest energy consumption. Other users will not constantly update their location and will only do so when creating an event or entering news It is desirable that the application, even in the background, allows the press of a bluetooth button to bring the application to the foreground and trigger a specific event. From the server side, the control of the user's status must be carried out according to the explanations that will be provided to the chosen company. Required platforms...

...sketch's operating on the variables received from the sensors. The sequence of events is triggered by using this touchscreen to post a query to get the new sensor values. An alternative display is found on the client's Android smartphone, and communicates with the Arduino via Bluetooth. [This method is preferred.] I have built a partly-functional proof-of-concept system, but I prefer to make another one, introducing one module and feature at a time, adding a new sensor or function only when the previous ones are working. The project would progress thus: 1) The nine preformatted .bmp images would be loaded onto the microSD card from the Windows 10-based laptop. 2) The independent variables would be requested and loaded to the same microSD card, through a dialog ...

Hi. I have two Adafruit nRF52840's. One is a CENTRAL and one is a PERIPHERAL. The Bluetooth standard for UART is a maximum of 20 bytes per packet transmission. I need someone who can work with me in C++ to design a data transmission system so I can send small or large amounts of data (EG: 8 bytes or 433 bytes) and have it automatically split the packet into equal parts of 20 bytes each so it can be sent from CENTRAL to PERIPHERAL. I am using the Arduino IDE to compile the code. Central (scroll down to 'Full Sample Code'): Peripheral (scroll down to 'Examples'): Thanks.

Bluetooth Low Energy Bluetooth Low Energy (BLE) signals from battery-driven beacons are at the core of the indoor location technology. It’s one of most prominent technologies that has emerged for indoor positioning and has become industry-standard available on most devices today. It uses so-called BLE beacons (or iBeacons) that are inexpensive, small, have a long battery life, and do not require an external energy source. The device (phone/watch etc.) detects the signal from the beacon and can roughly calculate the distance to the beacon, therefore estimating a users indoor location. How does BLE based Indoor Positioning work? 1. Positioning the user BLE beacons are the cornerstones of indoor positioning. With this technology, the device can detect when in range of a...
