Wireless programming or OTA (Over the Air) Programming can be done easily in ESP8266 and ESP32 as they have Wi-Fi support inbuilt on board. The only solution to this problem is by programming the Arduino wirelessly. And sometimes, it is very difficult to connect the board with PC if your project is fixed somewhere. On the terminal, we will see the message sent to the repeater from the sender, and the repeater forwards the data to the receiver dongle.Arduino Uno, the most popular microcontroller among electronics hobbyists and students and its pretty easy to get started with embedded systems using Arduino But one drawback of Arduino is that it needs to be connected to the computer using USB cable to upload the code as it has done have any onboard support for wireless communication. Similarly, run receiver and sender scripts accordingly on PC.Īs the name suggests, the repeater will repeat its content. Once we have repeater dongles id, we can put it on our scripts.įirst, move to the script directory on Raspberry pi, and using command prompt type sudo python3 repeater_example_repeter_dongle.py to run repeater script. Then do a gapscan using AT+GAPSCAN from the sender dongle and look for a dongle called BleuIO. To do that, we can simply advertise the dongle on Raspberry pi using the AT+ADVSTART command. We also need to know repeater dongles ID. Now open the scripts and set the ports number accordingly. Let’s make COM 5 as the sender & COM 6 as a receiver. On my PC, I have two dongles connected on ports 5 and 6. After connecting the dongles, open the device manager (windows) to find the ports of each dongle. You can do the process on three different PC or Raspberry Pi.įor this project, I have connected both the sender and receiver dongles to one PC. Once you cloned the script, you will find three different python script calledĬonnect two dongles on your PC. Let’s start by cloning the repository from Blueio Repeater Example. Steps to make Simple Bluetooth Low Energy Repeater Step 1: To Create a Bluetooth Low Energy repeater using multi-connection feature, we need the following tools. We have already created a sample script in python, which will help us to do the task. The repeater dongle will be connected to a Raspberry pi which will forward data to the receiver dongle. And that’s how a repeater will help us overcome the range limitation.įor this project, the sender dongle will scan for air quality data from the HibouAir device and pass the advertised data along with the timestamp to the repeater. At the same time, the repeater passes the data to the receiver dongle. Using this dongle’s multi-connection feature, we will make a simple repeater where one dongle scans nearby devices’ data and sends it to the repeater. The BleuIO is Bluetooth low energy solution that can be used to create new BLE 5.0 applications in the fastest and easiest way. This article will explain how to create a BLE Repeater using a BLE USB dongle called BleuIO and python. Fortunately, it’s easy to overcome this range limitation with the Bluetooth repeater. Sometimes the connection tends to drop or lag when you move a little further away from the device. However, despite the convenience, you can bear witness that the range offered can be a little limiting. Bluetooth low energy technology offers a suitable way of connecting smart devices. In this guide, we will learn How to make Simple Bluetooth Low Energy Repeater using multi-connection feature. Steps to make Simple Bluetooth Low Energy Repeater.
