  1. A BLE beacon broadcasts its identity to nearby Bluetooth devices, to enable the other devices to determine their location relative to the beacon, and to perform actions based on information broadcast by the beacon. Example applications of beacons include indoor positioning system, location-based advertising and more. From the definition of its purpose as a broadcast device, a BLE beacon thus cannot be connected to, and can only send information in its Bluetooth advertisement packets. There are several BLE beacon protocols. The Ameba BLEBeacon library supports the iBeacon and AltBeacon protocols.
  2. MQTT (Message Queuing Telemetry Transport) is a protocol proposed by IBM and Eurotech. IBM® Watson™ IoT Platform is, by the official definition, “A foundational cloud offering that can connect and control IoT sensors, appliances, homes, and industries. Built on IBM Cloud, Watson IoT Platform provides an extensive set of built-in and add-on tools. Use these tools to process IoT data with real-time and historical analytics, extract key performance indicators (KPIs) from your data, add “smarts” in the cloud for non-smart products, and securely connect your own apps and existing tools to the Watson IoT Platform infrastructure.” (IBM, 2020) This platform provides easy web interface to register, connect and visualize our IOT devices. For quick start and simple try-out, registration is not necessary, we may just run our program to get the device ID needed for this platform. Preparation § Ameba x 1 Example In this example, we will take a look at how to make use of IBM Watson IOT platform for out IOT project. Open the MQTT example “File” -> “Examples” -> “AmebaMQTTClient” -> “ibm_watson_iot_quickstart” Make sure the Wi-Fi information is properly filled in and we are ready to upload the code to ameba. Once uploading finished, open a serial monitor and we shall see information as follows, Important: Please take note of the string of characters on the first line of the picture above -- “clientId:quickstart:iotsample-ameba:ac35ee15608e” “ac35ee15608e” is the device ID as well as the MAC address of the ameba board used here which will NOT be the same for other cases, so make sure to copy down the device ID displayed on your serial monitor. Next, we click the IBM IOT platform link provided here and open our browser: https://quickstart.internetofthings.ibmcloud.com/#/ Paste the device ID we just copied into the box highlighted below, If the device ID keyed in is correct, some fake temperature data that our ameba published will be visualized like this, Done! Now you have FREE and working IOT cloud platform to help you visualize your IOT data in realtime~
  3. One of the most useful IoT applications is home security. Imagine a thief cutting your security camera wire while trying to break into your house. This won’t happen if your security system goes wireless and smart. This project demonstrates the capability of Realtek Ameba dev. board to conduct board-to-board communication via MQTT (FREE MQTT broker hosted at cloud.amebaiot.com). With this home security system, you will definitely be alarmed when your window/door is opened by the self-invited as the buzzer will make loud irritating noise while red LED flashes continuously. Of course, this project has left rooms to add your own logic to it. For example, sending MQTT messages to your phone to alert you, or to an IP camera to capture the image of the thief. Hardware Preparation - Ameba1 RTL8195AM x2 - Buzzer x1 - LED (red) x1 - Reed switch x1 - Magnet x1 - Jumpers x6 As 2 boards are needed to implement this project, there are 2 connection illustration as follows, https://github.com/Realtek-AmebaApp/Ameba_Examples/blob/master/RTL8195AM/006_HOME_SECURITY/WindowSecuritySystem_Switch_bb.png https://github.com/Realtek-AmebaApp/Ameba_Examples/blob/master/RTL8195AM/006_HOME_SECURITY/WindowSecuritySystem_Buzzer_bb.png Software Preparation 1. Check and make sure you have installed the ameba 1 board to Arduino IDE via adding this link into “additional boards manager URLs” under “Preference”, and install it in “board manager” under “Tools”, https://github.com/ambiot/amb1_arduino/raw/master/Arduino_package/package_realtek.com_ameba1_index.json 2. Copy the [buzzer source code](https://github.com/Realtek-AmebaApp/Ameba_Examples/blob/master/RTL8195AM/006_HOME_SECURITY/windowSecuritySystem_buzzer_Github.ino) and [switch source code](https://github.com/Realtek-AmebaApp/Ameba_Examples/blob/master/RTL8195AM/006_HOME_SECURITY/windowSecuritySystem_switch_Github.ino) you find in this repository to your Ameba1 RTL8195 boards respectively using arduino IDE 3. In order to connect to WiFi and MQTT server, you need to key in your WiFi SSID, WiFi passowrd, MQTT username and MQTT password, - username: same as your amebaiot.com username - password: same as your amebaiot.com password Done that's it! You have created a simple yet powerful home security system! To watch how how it is done, click link below,
  4. The project demonstrates how an IoT device (Ameba RTL8195) is applied in real-life scenarios. If you have watched previous demo videos, you should have no problem understanding how an LCD display, a DHT Temperature Humidity sensor and our Ameba RTL8195. It can be put together to form a fully functional smart weather station. Simply follow the instructions in our examples as follows to DIY your own weather station, 1. LCD 24H Clock https://www.electronics-lab.com/community/index.php?/topic/47704-realtek-ameba-rtl8195-lcd-24h-clock/ 2. MQTT https://www.electronics-lab.com/community/index.php?/topic/47715-realtek-ameba-rtl8195-mqtt-demo/ 3. DHT+MQTT https://www.electronics-lab.com/community/index.php?/topic/47735-realtek-ameba-rtl8195-iot-system-with-dht-mqtt/ The key to integrate these 3 examples successfully is to make sure that you have set up your MQTT server correctly and note that here we are using a different set of MQTT topics, namely “dht_data” and “dht_status”. Also, when connect DHT sensor, D13 pin is used as data input pin.

  5. Do you want to always keep track with the time of place of your interest without having to google it? Then this project is what you are looking for! This LCD Real-Time Network Clock make use of Network Time Protocol (NTP) together with a WiFi-enabled IOT microcontroller--Realtek Ameba 1 (RTL8195AM/ RTL8710AF) to create the product that you need. All you need to do is to let the microcontroller know which area's time that you would like to see and key in your WiFi SSID and password and that's it ! No matter how many time the power is off, or you have moved, as soon as it's powered back on and connected to the network, it will tell you the rigth time instantaneously! And of course, if you are arduino-savvy, you can program this product to read out the time or even control the lightings in your room accroding to the time bocause the soc used in the microcontroller is so powerful that it's able to connect more than dozens of devices and run multiple tasks simultaneously. For DIY upgrading this project, you may refer to www.amebaiot.com for more information.
  6. This is a simple IoT project based on the “mqtt basic” example that comes with the Arduino package when you install the RTL8195 on Arduino IDE. In this project, simple passive components are used to aid in demonstrating the power of bidirectional communication of MQTT protocol which is widely used in modern IoT applications for its advantages in speedy response and lightweight. In the video, an android tablet was used as a MQTT client and our Ameba RTL8195. Board acted as another MQTT client communicating with the android tablet. Both client have to connect to the same MQTT server before proceeding to the next step, you may choose to set up own MQTT server or using an online free server.

  7. Hi, I would to share what i found recently. The AmebaIoT RTL8195 board. Looks like it is a very powerful board for IoT and WiFi related projects. I am going to dig more about it and sharing more myself DIY projects with you guys. Hope you guys can give me some technical suggestions about my project. Please refer to the video link, This video is a small embedded project named “LCD 24H Clock” featuring RealtekTM Ameba RTL8195 development board as the microcontroller. The Ameba board is pre-programmed with code written in Arduino IDE and connects to the LCD screen via I2C protocol. The 24H clock is capable of displaying hour, minute and second on the LCD screen and counting up to 24 hours. It will reset itself after time has passed longer than 24 hours.
