- Wallet Should support iOS and Android platform for multiple screen resolution - It should support offline payment using bluetooth/NFC mechanism - Should have parent/child model to be accessed to same wallet account Preferably using Ethereum blockchain. Or suggest any other.

We require to build an Android app that interact with a device using bluetooth low energy, send commands to the device and receive info from the device. Further details will be discuss with professionals with proper skills to develop this project.

Create the firmware for a low power BLE sensor device. There are two i2c sensors that need to be read, and share their readings via the BLE notify method. The hardware is ready to go, I have created basic poc software to read from one of the sensors, needs to be finalised and optimised for low power.

Creating a smart wearable tracker. We are looking to switch our current hardware from esp32 to the Nordic thingy 91. We need help setting up and programming Nordic thingy 91 to connect with our mobile app. It needs to have features for 1. Nb iot 2. Bluetooth 3. NFC 4. Led light 5. Step count 6. Gps

I have an app built on Flutter. One of this functionalities of this app is to connected with a device and exchange data over BLE. Everything works fine on iOS, but on Android, it will only connect, no data is sent or received. If you have experience working with BLE, apply for the project. I won’t talk to freelances who send ore made messages, take the time to read the job post and respond accordingly.

Wir, m.i.k. IT GmbH, sind auf der Suche nach einem Proof of Concept darüber, ob es möglich ist eine Android App zu entwickeln die sich dafür eignet, den Standort von Kleingeräten über Bluetooth Low Energy in Kombination mit dem GPS des Smartphones zu erfassen.

We need a developer to quickly implement some BLE features in to our application. You will need an NRF52832 dev kit to complete this task. The job is simple and we are not looking for someone to complete the full application. Just to assist our development team by quickly implementing the 4 characteristics our device uses.

Experience developing, testing and launching at least 2 sensor data based mobile applications, 2 years practical experience using React Native, React, or Swift, Kotlin . In-depth knowledge of working with data driven workflow implementation and REST APIs, Experience in processing signals dynamically on arduino

WE have an application which is scanning continously for ble devices and reading their advertised values. Note: We don't pair the device here..directly, read the values. Requirement is, instead of continously scanning, we want to listening in passive mode for BLE devices. i.e, observing for values coming in from sensors. can you support with this. No, front end part needed , just need to introduce listening mode to the application.

Hello. Your task is to build a simple demo that enables a user to share his/her screen with another user without using the internet. The technology to be used here is Bluetooth and Wifi ... Similar to the technology behind airdrop. It should allow one user to broadcast his/her screen to a local audience. NB: No sound is required for the initial demo

I have a nrf52 pcb board with peripherals on i2c bus and leds driven by cpu output. I' d like to create the firmware to control the lamp into Segger environment but i never used it.
