Posted on by Rakesh Kumar, Ph.D.

A compact embedded board from LILYGO with Wi-Fi/BL5.0 and the SIM7080G module for CAT-M and NB-IoT connectivity has been launched recently. The SIM7080G is an SMT-type Multi-Band CAT-M and NB-IoT module. It is easy to add on to because it has many interfaces, such as UART, GPIO, PCM, SPI, I2C, etc. The module gives the customer’s application a lot of freedom and makes it easy to integrate. It was made for applications that need to send and receive data with low latency and low throughput in a variety of radio propagation conditions.

The SIM7080G module is great for M2M applications like metering, asset tracking, remote monitoring, E-health, etc., because it has a unique mix of performance, security, and flexibility. Additionally, the board is based on the ESP32-S3 SoC. An SD card slot, a SIM card slot, camera support, a 18650 battery holder, and a connector for solar input are just a few of the adaptable peripherals that the T-SIM7080G provides. The ESP32-S3 module is present in the T-SIM7080G, just as it was in the T-TWR Walkie Talkie module that was released last month. Xtensa 32-bit LX7 dual-core (up to 240MHz); 16 MB Flash; 8 MB PSRAM; 2.4GHz Wi-Fi/BLE 5.0; these are the specifications for the ESP32-S3 board.

The board has up to 24 GPIOs, 13 ADC pins, 10 Touch pins, 2 UARTs, and 2 SPIs, according to the pinout image below. The solar power connector appears to support 4.4 V to 6.0 V.

Electronic Shelf Label (ESL) Support is available in Bluetooth 5.4

Posted on by Rakesh Kumar, Ph.D.

The Bluetooth 5.4 Core Specification, which includes features like PAwR and EAD created for Electronic Shelf Label (ESL) systems, has just been adopted by the Bluetooth Special Interest Group (SIG). A new wireless standard for the ESL market was announced by Bluetooth technology. ESL systems have, up until now, relied on exclusive wireless communication protocols, which could be a barrier to widespread adoption. Leaders in the ESL industry collaborated with the Bluetooth SIG to develop a scalable, ultra-low power, highly secure ESL wireless standard based on Bluetooth technology in order to address this issue.

Following the adoption of the Bluetooth 5.3 Core Specification in August 2021 with a number of improvements, Bluetooth 5.4 is now available with features that seem to be most appealing for large-scale Bluetooth networks that support bi-directional communication with thousands of end nodes from a single access point, as would be the case for ESL or Shelf Sensor systems.

Bluetooth 5.4 has gotten four new features. Firstly, Periodic Advertising with Responses (PAwR) is a new Bluetooth Low Energy (LE) logical transport that allows energy-efficient, two-way communication between up to 32,640 devices in a large-scale one-to-many topology. Groups can also be given devices that only let them listen to the transmissions of their own group. In this part of the specification, there is also a definition of an ESL profile.

Secondly, Encrypted Advertising Data (EAD), a new feature, gives advertising packets a standard way to send data securely over the air. The main benefit is that it makes it possible to encrypt data that is shared through periodic ads and responses. Thirdly, LE GATT Security Levels Characteristic has been included. Which a new GATT characteristic called LE GATT Security Levels lets devices show the security mode and level needed for all their GATT features to work.

Finally, the Advertising Coding Selection feature allows the host to choose between two long-range coding options (S=2 or S=8) that can be used with LE extended advertising. The FEC (Forward Error Correction) S parameter controls how much data is made to fix errors and how far Bluetooth can reach. S=8 increases the range by a factor of around four compared to the range achieved with the LE 1M PHY, but it lowers the protocol data rate to 125 kbps. S=2 increases the range by around 2, but it lowers the protocol data rate to 500 kbps.

The good news is that Bluetooth 5.4 support does not appear to require new hardware, only new firmware, according to Silicon Labs, who state that their BG22 and BG24 microcontrollers can be used for Bluetooth 5.4 devices, while the BG21 family would be integrated into access points.

On the Bluetooth website, you can access the Bluetooth 5.4 Core Specification. Still, given that it’s over 3000 pages long, you might prefer to read the technical overview for more information on the new features.

Both a blog post and a press release contain additional details.

It also has a wide range of other applications, but it does not include the 0.85-inch display or the IMU sensor that is included in the ATOM S3 development kit. Instead, it uses an RGB LED in its place.

The M5Stack ATOM S3 Lite has an ESP32-S3FN8 WiFi and Bluetooth System-on-Chip (SoC) with 8MB SPI flash, an infrared transmitter, a USB-C port for power and programming, a few I/O pins, user and resets buttons, and it all fits into a housing that is only 24 x 24 mm and 9.5 mm thick.

Specifications

  • It includes a dual-core 32-bit Xtensa LX7 microcontroller from Espressif Systems with AI vector instructions up to 240 MHz, a RISC-V ULP co-processor, 512 KB SRAM, 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 BLE + Mesh, and 8 MB flash memory.
  • It has a “3D” antenna built right in.
  • In addition, an extension for 9x pins is provided, complete with GPIOs G5, G6, G7, G8, G38, and G39, as well as 5V, 3.3V, and GND, and a connector for Grove with four pins.
  • In addition to that, there is an infrared LED (transmitter/blaster), a WS2812B-2020 RGB LED with user buttons, and a reset button.
  • It has a screw hole for an M.2 screw already installed.
  • A power supply of approximately 5V is available via the USB Type-C port, and an SY8089 5V to 3V DCDC converter is also included.
  • The temperature range is from 0 to 40 degrees Celsius, and the dimensions are 24 by 24 by 9.5 millimeters. It weighs approximately 5.3 grams.

The M5Stack ATOMS3 Lite controller, just like other Atom boards, can be programmed using Arduino or the company’s UIFlow web-based visual programming integrated development environment (IDE). The illustration that is displayed below indicates that MicroPython is also supported; however, MicroPython is not mentioned in the documentation, so you may be on your own in this regard. What you do get there, however, are some details about the hardware as well as an Arduino sketch that was designed specifically for the ATOMS3 because it draws colors on display, which the Lite model does not have.

The primary scenario for this type of IoT controller is managing a Smart Home’s network of interconnected WiFi and Bluetooth devices and IR-enabled electronics like televisions, air conditioners, set-top boxes, and more. However, the I/Os ports allow for a wide variety of other uses, including sensor monitoring, relay control, and more. It could even be used as a BLE to MQTT gateway. The ESP32-S3’s vector instruction set makes it a great choice for machine learning.

M5Stack is currently offering ATOMS3 Lite for sale at the price of $7.50 plus shipping. If you would rather have a color display that is 0.85 inches in size along with an IMU sensor, the ATOMS3 can be purchased for $15.50
