Amazon‚s website has introduced a Software Audio Front End (AFE) Development Kit section that lists software algorithms that optimize sound detection in noisy environments. The latest addition is the Amazon Alexa recently certified Espressif audio front end or ESP AFE algorithm for shorts.
The Espressif AFE algorithm was certified by Amazon after achieving excellent performance in long-range Alexa testing. In most cases, in low signal-to-noise scenarios, the wakeup rate reaches 100% and the speech recognition rate exceeds 90%.
Espressif’s AFE algorithms are optimized, as they take advantage of Espressif’s AI accelerator that is available in the ESP32-S3 SoC. Espressif’s AFE algorithms consume just 12-20% of CPU and around 460 KB of memory, including 220 KB of internal memory and 240 KB of external memory. This provides sufficient headroom for customer applications on the ESP32-S3 SoC.
Espressif’s AFE algorithms offer an easy and intuitive API for customer applications, so that their performance can change as dynamically as it is required. The distance between the two microphones can be between 20-80 mm, which allows considerable flexibility for the hardware design of developers’ end-products.
One of industrial IoT devices, supporting Espressif’s ESP32 technology is eModGATE from TECHBASE. Economical, ESP32-based solution can serve as an end-point in any installation or works well as a gateway, gathering data from scattered sensor mesh across the installation.

Espressif Systems and Amazon recently announced the ESP32-PICO-V3-ZERO Alexa Connect Kit (ACK) module, which provides support for features such as out-of-the-box connectivity to the cloud service ACK, Alexa control, „seamless setup”, and Amazon Dash completion for connected devices.
With Alexa Connect Kit, you can make nearly any device with power into an Alexa-compatible smart device your customers will love, all at a fixed per-device cost. You simply integrate an Amazon-managed ACK module into your device, connect it to your device’s microcontroller (MCU) over a serial interface, and add interface code to your device’s firmware to interpret control messages from the ACK module. The ACK module adds Wi-Fi, Bluetooth LE, and all the software needed for Alexa control, Frustration Free Setup, security, and log and metric collection – managed and updated by Amazon. For your customers, products built with ACK include Alexa control through voice and the Alexa app, and the option to support Amazon Dash Replenishment. For developers, ACK enables you to connect your devices to Alexa without the need to operate a cloud, create and maintain an Alexa skill, develop a companion app, or deal with IoT firmware integration. With an ACK module on your device, you can focus on building great hardware.

First major announcement is that Sigfox will launch a private network (PAN) that will allow IoT customers to choose private and global services according to their needs. The service was launched for the first time in France in the first quarter of 2020, but Sigfox will be implemented in over 65 countries.
The operator’s wide area network (WAN) will be completed next year in cooperation with Eutelsat. Sigfox provides coverage worldwide using the nano-satellite constellation launched by Eutelsat.
The Sigfox PAN offer will benefit from the existing Sigfox WAN ecosystem. Thanks to the potential to use all components on the market and the use of very low transmit power to support facilities without the need for batteries, the Sigfox PAN offer offers enormous potential,
Ludovic Le Moan, CEO and co-founder of Sigfox.
According to Sigfox, by the end of 2019, there will be more than 15 million registered facilities and over 1,500 customers using this solution in various industries around the world. Sigfox says that PAN customers can expect the same as WAN customers in terms of support and quality. PAN clients can choose to subscribe to additional „WAN Extension” services if needed if the device needs to communicate outside the local network.
Sigfox improving the accuracy of Atlas geolocation services
Internet of Things operators have now launched Atlas Native Complimentary. It is made available free of charge in exchange for the rights to process data regarding GPS data. These data are compared to the fingerprint of the Sigfox network using machine learning, which increases accuracy to 800 meters.
To further increase the accuracy of its geolocation services, Sigfox said it has completed the global implementation of Atlas WiFi in collaboration with HERE Technologies’ mapping experts.
Sigfox uses the global WiFi access point database here. Access points are checked by the Sigfox WiFi tracking module and more closely track the location of external and internal resources with less battery consumption than using GPS.
We are delighted to strengthen our partnership with Amadeus and share our combined expertise to create real digital transformation of the travel sector. Our strategic alliance named PinPoint will not only help to improve the travel experience, but this will also change completely the game for an industry looking for decades for THE technology able to save costs while improving efficiency and quality of services

ESP-MESH is a network protocol based on the Wi-Fi protocol. ESP-MESH enables the connection of a large number of devices (hereinafter nodes) covering a large physical area (both inside and outside) over a single WLAN (wireless local area network). ESP-MESH self-organizes and self-heals, allowing you to build and maintain networks autonomously.
Traditional Wi-Fi Network Architecture. Source: espressif.com
Traditional Infrastructure of Wi-Fi network is a point-to-multipoint network in which a single central node called an Access Point (AP) is directly connected to all other nodes called stations. The AP is responsible for arbitrating and forwarding transmissions between stations. Some access points relay transmissions to and from external IP networks through routers.
Traditional Infrastructure Wi-Fi networks have the downside of having a limited coverage area as all stations need to be in range to connect directly to the access point. In addition, the maximum number of stations allowed in the network is limited by the bandwidth of the access point, making traditional Wi-Fi networks prone to overload.
ESP-MESH vs traditional Wi-Fi infrastucture
ESP-MESH differs from traditional Wi-Fi infrastructure networks in that the nodes do not have to connect to a central node. Instead, the node can connect with its neighbors. Nodes are responsible for relaying transmissions to each other. This allows for achieving interconnections without the need for nodes to be within the range of the central node, which significantly extends the coverage area of the ESP-MESH network. Likewise, ESP-MESH is less prone to congestion as the number of allowed nodes in the network is no longer limited by a single central node.

Some time ago, we wrote about the premiere of Espressif’s ESP32-S2 chip. Check out the summary from Adafruit team on the ESP32-32 features.
Battery-ready IoT devices based on ESP32
Battery / SuperCap power support allows the processes and data to be securely executed, saved or transferred, and the operating system to be safely shutdown or reboot, if the power source has been restored. The power failure alert can also be sent to cloud service, to perform custom task, specified by user or self-learning AI algorithm.
The Moduino device is a comprehensive end-point controller for variety of sensors located throughout any installation. It fully supports temperature and humidity sensors and new ones are currently developed, e.g. accelerometer, gyroscope, magnetometer, etc.
Moduino–ModBerry symbiosis allows wide range of wake-up/sleep schedule customization, in order to perform best and save energy accordingly to power supply state. Arduino and MicroPython environments provide libraries to control different scenarios of data and power management.
With built-in algorithms and the possibility to program on your own, the TECHBASE’s sleep/wake addon module can wake the device using schedule/timer. Another option is wake on external trigger, e.g. change of input, etc. All the options for sleep, shutdown and wake can be configured for various scenarios to ensure constant operation of devices, safety of data and continuity of work in case of power failure in any installation.
