How do I connect my Android to BLE?

Connect BLE device to Android an Send Data (nUART)

  1. connect to the device (static MAC-address)
  2. connect to the nordic-UART-service.
  3. receive texts from the Feather.
  4. implement surveillance of the connection.

How do I make a BLE server?

For creating a BLE server, the code should follow the next steps:

  1. Create a BLE Server. In this case, the ESP32 acts as a BLE server.
  2. Create a BLE Service.
  3. Create a BLE Characteristic on the Service.
  4. Create a BLE Descriptor on the Characteristic.
  5. Start the Service.
  6. Start advertising, so it can be found by other devices.

What is BLE Android?

Bluetooth Low Energy (BLE), available in Android 4.3 and later, creates short connections between devices to transfer bursts of data. This lets BLE provide lower bandwidth and reduced power consumption compared to Classic Bluetooth. It is ideal for applications such as a heart-rate monitor or a wireless keyboard.

How do I make a ble app?

The process of developing the mobile app can be summarized as follows:

  1. Get a Bluetooth Device running.
  2. Install Evothings Tools in your PC and your phone.
  3. Select an example from the Evothings list of examples.
  4. Modify the example by using the UUIDs from your BLE Device.
  5. Connect your phone to your BLE Device to control it.

What is a BLE server?

The BLE supports two types of modes such as Broadcast mode and Mesh network mode. In broadcast mode, the server transmits data to many clients that are connected and in a mesh network mode, all the devices are connected. Both server and client have a “SERVICE UUID” to make a connection between server and client.

What is a BLE profile?

A BLE profile serves as an application layer for specific and already defined use cases. Generally speaking, a BLE profile is a standard collection of services for a specific use case.

How does Bluetooth BLE work?

Discovery of BLE devices BLE devices are discovered through the broadcasting of advertising packets over 3 separate frequencies to reduce interference. A BLE device sends out a repetitive packet of information over one of three channels with random delays of up to 10 milliseconds.

What is Ble (Ble) in Android?

BLE was introduced in Android 4.3 (API level 18) as built-in platform support in the Central role. Android provides APIs to discover devices, query for services and transmit information by the applications. Mobile app (for example, Home Automation Android Application) sends and receives data via BLE

What is Bluetooth Low Energy (BLE)?

Bluetooth Low Energy (BLE) is the intelligent, power-friendly version of Bluetooth wireless technology. It is also marketed as Bluetooth Smart, started as part of the Bluetooth 4.0 Core Specification. BLE plays a role in the creation of smarter, more compact, more affordable, less complex devices.

How do I add ble capabilities to other devices?

This application can be adapted to add BLE capabilities to other devices by connecting a nRF capable device to them. This could be through GPIO, SPI, UART, or I2C. Future articles will show some examples of doing this. Have fun! Give this project a try for yourself!

What is BLE and why do we need it?

BLE plays a role in the creation of smarter, more compact, more affordable, less complex devices. It was designed by Nokia initially as Wibree before being adopted by the Bluetooth Special Interest Group (SIG). BLE was introduced in Android 4.3 (API level 18) as built-in platform support in the Central role.
