T2-U WiFi and Bluetooth development board supports the Tuya Smart Home framework

The T2-U is a development board compatible with the Tuya Smart Home framework that features a WiFi and Bluetooth module with a 120 MHz RISC processor, some buttons, an LED indicator, GPIOs, power, and a USB-to-serial chip. In 2019, we covered Tuya as a one-stop Smart Home solution allowing companies to easily design and manufacture home automation devices from electronics to the enclosure. For example, the company provides a customizable 4-inch Android touch control panel & Zigbee gateway as well as the Tuya Link SDK allowing customers to further customize the firmware of their Smart Home devices, but I had yet to see a development board compatible with Tuya. T2-U development board specifications: Wireless module – T2-U SoC – Unnamed 32-bit RISC MCU @ 120 MHz with 2 MB flash and 256 KB RAM Wireless Wi-Fi 802.11b, 802.11g, and 802.11n wireless standard. Channels 1 to 14 at 2.4 GHz. Security […]

Remote.It adds Bluetooth assisted WiFi configuration to Raspberry Pi SBC’s

Remote.It, a company providing remote access services, has released an open-source project to enable Raspberry Pi WiFi network configuration using Bluetooth (BLE), so users can easily configure WiFi on the board by simply using their smartphone. Configuring WiFi on a Raspberry Pi usually involves either: Manual configuration – The user connects a monitor and keyboard to the Raspberry Pi to configure the wireless network directly on the device. Pre-configured SD cards, NVMe SSDs, or USB drives – The WiFi ESSID and password can be set in Raspberry Pi USB imager, and the Raspberry Pi will automatically connect to the network at boot time. That’s quick, but less flexible since the credentials can’t be modified after deployment, and it only works when using a single wireless network. Remote.It offers a third option for WiFi provisioning using Bluetooth LE. The Raspberry Pi can run headless or fully enclosed into a product, and […]

The Blette Stick relies on Bluetooth 5.0 LE for off-grid messaging with up to 1.1km range

Blette Stick Bluetooth LE offgrid communication

The Blette Stick is a Bluetooth 5.0 LE USB-C dongle designed to be attached to an Android smartphone in order to provide off-grid messaging and GPS coordinates sharing capabilities with a range of up to 1.1km in case WiFi and cellular networks are down. CNX Software readers may also be familiar with Meshtastic devices relying on WiFi to connect to the smartphone with Bluetooth and to other nodes using LoRaWAN to enable off-grid messaging while trekking or during emergencies. The Blettle Stick does something similar to the Meshtastic project but with Bluetooth LE long-range communication instead of Bluetooth+LoRaWAN. While the range will be shorter and limited to around 1km (line-of-sight), the plug-and-play design will make it easier to use for typical users who are not technically savvy. Blettle Stick specifications: SoC – Nordic Semi nRF52 Bluetooth 5.0 LE microcontroller (exact part number not specified, possibly nRF52840) Wireless – Bluetooth 5.0 […]

Qsen-07 multi-sensor wireless board can detect CO2, VOC, temperature, humidity, ambient light, and attitude

The Qsen-07 multi-sensor board is an ESP32 wireless development board that combines several useful sensors into one device, making it easier to control, monitor, and enhance your home environment. It is a recent product from Maker Go, a China-based hardware company, which claims the board is “fully integrated with ESPHome and Home Assistant“. But as noted in a reader’s comment below, ESPHome on ESP32-C6 is still a work in progress, and the YAML configuration file for the board has yet to be provided by the company. The Qsen-07 multi-sensor board is “designed for health-conscious and tech-savvy homeowners” and can monitor air quality and other environmental variables to ensure a safe and smart living space. It features up to seven sensors, including two air quality sensors, a temperature and humidity sensor, an ambient light sensor, a barometric pressure sensor, an attitude gyro sensor, and an optional radar sensor. The Aosong AGS10 […]

Zigbee Coordinator CC2652P7 1.0 runs open-source firmware, works with Zigbee2MQTT, Home Assistant, and ioBroker

The cod.m Zigbee Coordinator 1.0 (CZC 1.0) is a hybrid ZigBee coordinator that can be used to connect devices over a network (Ethernet/Wi-Fi) and USB. The ZigBee Coordinator version 1.0 is an upgrade of version 0.2 released in 2022. The CZC 1.0 replaces the Texas Instruments CC2652P2 chip with the much more powerful CC2652P7 chip, uses an ESP32-WROOM-32E module instead of the USR-K6 chip, and adds compatibility with Home Assistant (ZHA integration). It can create a Zigbee network and pair Zigbee devices over Ethernet, WiFi, or Serial (USB). It features the same Texas Instruments CC2652P7 chip as the SMLIGHT line of Zigbee Ethernet/WiFi/USB coordinators and USB dongles. There are two models of the CZC 1.0: a Power over Ethernet model and a model that can only be powered via USB-C. cod.m Zigbee Coordinator specifications: Zigbee SoC – Texas Instruments CC2652P7 Arm Cortex-M4F microcontroller @ 48 MHz with 704 KB flash, […]
