wolfIP – An open-source, lightweight TCP/IP stack with no dynamic memory allocations for embedded systems

wolfip TCP/IP library no memory allocations

Better known for its open-source wolfSSL SSL/TLS library, wolfSSL (the company) has now released the wolfIP open-source, lightweight TCP/IP stack with no dynamic memory allocations (e.g., no malloc calls) designed for resource-constrained embedded systems.

The company highlights that wolfIP “supports both endpoint-only mode and full multi-interface support with optional IP forwarding. By default, it operates as a network endpoint, but can be configured to forward traffic between multiple network interfaces”.

TrustTunnel is an open-source, high-performance VPN protocol that’s harder to detect and block

How TrustTunnerl AdGuard VPN protocol works

Adguard VPN is a commercial VPN solution, but the company has decided to open-source the VPN protocol and named it TrustTunnel. It’s described as a modern, secure, mobile-optimized VPN protocol. Since there are plenty of VPN protocols, including WireGuard and OpenVPN, it felt redundant at first. But AdGuard explains that those are easy to detect and block at the network level, and methods to conceal VPN traffic, such as wrapping VPN data in a TCP connection, often reduce speed. TrustTunnel relies on a different method and blends in with regular HTTPS traffic through TLS-based encryption, and HTTP/2 or HTTP/3 transport. Each connection runs on its own dedicated stream, which combines packets for more efficient transmission. The diagrams above and below illustrate this by showing that four hops are required for a standard concealed VPN, and only two hops with TrustTunnel. The company also says it is optimized for mobile platforms […]

SMHUB Nano Mg24 compact Linux-based Zigbee/Thread Smart Hub combines SG2000 RISC-V SoC with MG24 wireless MCU

SMLight’s SMHUB Nano Mg24 may look like the company’s earlier SLZB-06p Zigbee to Ethernet/WiFi/USB coordinators, but it’s a more powerful Linux-based Zigbee/Thread Smart Hub that pairs SOPHGO SG2000 RISC-V SoC with Silicon Labs MG24 multi-protocol wireless MCU. Unlike traditional Zigbee/Thread adapters that connect to a host through USB or Ethernet, the SMHUB Nano Mg24 is an all-in-one solution that runs all major automation apps directly on the device, eliminating the need for a Raspberry Pi, Mini PC, or other hardware server. SMHUB Nano Mg24 specifications: SoC – SOPHGO SG2000 CPU cores 1x C906 64-bit RISC-V core @ 1GHz or 1x Arm Cortex-A53 core @ 1GHz (selectable at boot) 1x C906 64-bit RISC-V core @ 700MHz MCU – 8051 8-bit microcontroller core @ 25 to 300 MHz with 6KB SRAM GPU – None VPU – H.265/H.264 video decoding and encoding (5M @ 30fps) ISP – 5M @ 30fps NPU – 0.5 TOPS Memory […]
