Bluetooth is a popular wireless technology that has been around for many years. It’s been used in many different products, from smartphones and tablets to fitness trackers and medical devices.

This app is the best and simplest way to create a Bluetooth connection. It’s very easy to use and doesn’t require any other hardware or software. It’s a UART (Universal Asynchronous Receiver/Transmitter) protocol that allows you to send and receive text and other data.

You can use it to communicate with other devices that are connected to the same UART. This is possible in all the supported nRF boards.

This app works with the nRF Bluetooth low energy shield.
