Ai-Thinker BW16 is a dual-band WiFi & Bluetooth 5.0 IoT module (Sponsored)

Ai Thinker BW16 dual-band WiFi BLE 5.0 module

Many users prefer the ESP32 when implementing WiFi & Bluetooth into their IoT projects. But Ai-Thinker BW16 offers dual-band WiFi 4 & Bluetooth 5.0 connectivity through Realtek’s RTL8720DN chipset which may provide more reliable connectivity where the 2.4 GHz band is crowded. The module integrates an Arm Cortex-M4F compatible high-performance MCU, an Arm Cortex-M0 compatible low power MCU, WiFI 802.11 a/b/g/n, MAC, Bluetooth and RF baseband, and provides a set of configurable GPIO ports to control peripheral devices. BW16 module One significant difference between BW16 and ESP32 module is that it has two serial port interfaces, so attention should be paid to the wiring of the UART interfaces. The following diagram shows the two serial interfaces of the BW16 module. One of the module serial interfaces is used to send and receive AT commands to control connectivity from a host processor or microcontroller, while the other serial port is used […]

Realtek AP-Router SDK vulnerabilities could impact millions of routers and IoT devices

The IoT Inspector Research Lab has discovered four high and critical vulnerabilities in the Realtek AP-Router “Jungle” SDK used for RTL819x SoCs that could impact millions of WiFi routers and dongles. An attacker can use a network attack, e.g. without physical access to the device, to generate a buffer or stack overflow helping him access the system and execute his own code. Realtek has released an advisory (PDF) with patchsets for all four vulnerabilities so you should upgrade the firmware if you can. Summary of the four vulnerabilities: CVE-2021-35392 – Realtek Jungle SDK version v2.x up to v3.4.14B provides a ‘WiFi Simple Config’ server called wscd or mini_upnpd that implements both UPnP and SSDP protocols. The server is vulnerable to a heap buffer overflow that is present due to unsafe crafting of SSDP NOTIFY messages from received M-SEARCH messages ST header. CVE-2021-35393 – Also impacts ‘WiFi Simple Config’ server (wscd […]

$6 Rtlduino RTL8720DN dual-band WiFi IoT board features 2.4/5GHz Wireless MCU

There are plenty of WiFi modules for the IoT market, but those usually work at 2.4 GHz only. This may be an issue in areas where the 2.4 GHz spectrum is overcrowded. But two years ago, we were pleased to see the Ameba Z2 board offering dual-band (2.4GHz and 5Ghz) WiFi thanks to Realtek RTL8720CM wireless MCU, and last year, we discovered B&T BW16 dual-band IoT module based on RTL8720DN sold for under $4 before shipping. If you like the cheap price of the module, but do not feel like creating your own baseboard, or soldering wires to the module, you’ll be glad to know Rtlduino RTL8720DN board offers an easy way to evaluate RTL8720DN dual-band WiFi (and Bluetooth LE 5.0) microcontroller as it is fitted with a B&T BW16 module and comes in a form factor similar to NodeMCU ESP8266 board. Rtlduino RTL8720DN board Specifications: B&T BW16 wireless module […]

Testing Hercules OTT Realtek RTD1395 4K Android STB Development Board

This is a guest post by Promwad, a software and hardware product development company with DTV & STB development expertise and know-how. Recently, they received a package from Realtek, their partner in Taiwan. There was a Realtek RTD1395 development board inside – Hercules 32-bit OTT – with 2 GB RAM and pre-installed Android 9 OS. Promwad team tested what it’s capable of and how it can be used by hardware and software engineers who design new TV set-top boxes and develop embedded software. Hercules OTT board is an Android IPTV box that plays videos of any formats with a maximum resolution of 4K. Streaming services such as Youtube, Netflix, etc. are supported via Dash and HLS. Also, the board supports other Android apps, including audio/video calls and conferencing. Realtek introduced RTD1395-based boards back in 2018. IP and cable TV operators used them in their subscriber devices. The RTD1395 chip with […]
