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

Tuya T2-U development board

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.

LILYGO T-Halow is an ESP32-S3 board with long-range WiFi HaLow, OV2640/OV5640 camera support

ESP32-S3 WiFi HaLow board

LILYGO T-Halow is an ESP32-S3 board equipped with a WiFi HaLow module with up to 1.2km range, a connector compatible with OV2640 and OV5640 camera modules, and an 18650 battery holder for power, as well as several GPIOs for expansion. We first wrote about 802.11ah low-power long-range WiFi standard operating at 900 MHz in 2014, but adoption has been slow and we’ve seen a few 802.11ah (WiFi HaLow) chips from Newracom and Morse Micro over the years, as well as USB adapters, a Raspberry Pi HAT, a mini PCIe card, gateways, and some development boards. All those rely on a Linux host, but the LILYGO T-Halow features a TX-AH WiFI HaLow module from Taixin Semiconductor that’s controller by AT commands through an ESP32-S3 or a micro USB port. LILYGO T-Halow specifications: Wireless modules ESP32-S3-WROOM-1 wireless module SoC –  ESP32-S3 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 […]

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

Remote.it Dashboard

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 […]

How to easily enable MediaTek MT7922 Bluetooth on Ubuntu 24.04

MT7922 Bluetooth Ubuntu 24.04

MediaTek MT7922 WiFi 6 and Bluetooth 5.3 modules have recently been found in several mini PCs, but Bluetooth would not work in Linux due to a lack of drivers. In this post, we’ll show how to easily enable Bluetooth in MediaTek MT7922 modules when running Ubuntu 24.04. We previously noted that Ian Morrisson submitted a patch adding the IDs for the MT7922 module (Azurewave AW-XB591NF) used in recent GEEKOM mini PCs last March. In theory, you could have rebuilt the Linux kernel, but now that Linux 6.10 has been released, it’s much easier since Canonical has made the Linux 6.10 kernel available for Ubuntu, so we only need to install it and problem solved! Ubuntu 24.04 ships with Linux 6.8, we can see a Bluetooth opcode error in the kernel log.
