Review of GL.inet GL-S10 BLE to MQTT gateway with MQTT X open-source client

GL.inet GL-S10 review

I started the review of GL.inet GL-S10 BLE to MQTT gateway in December by doing an unboxing and a teardown of the ESP32 gateway and BLE beacon provided. I’ve now had to play with the device and recommended app and software, and it took longer than expected since I encountered several issues during testing, most of which should now be resolved with new firmware, and documentation will be updated very soon. I mostly followed the steps from the detailed user manual for this review. The first time I did was to install the GL-S10 Tool App for Android, then power the gateway while pressing its button to enter pairing mode and soon enough the gateway was detected. Note you should probably not share the MAC address of your devices as there’s no security by default, and anybody would be able to access the information with the tools we’ll use below. […]

Lantronix G520 cellular gateways target industrial communication, cybersecurity, and transportation

Lantronix G520

Lantronix G520-series 4G LTE Cat 4 and 5G cellular gateways are designed to address challenges in Industry 4.0, security, and transportation markets with three/four separate gateways all based on an unnamed ARM926EJ-S-based CPU running at 600 MHz that’s most likely Microchip SAM9X60 processor introduced in 2020. All gateways are from the same base with variation for specific markets: G526 Industrial Gateway with LTE Cat 4 Ethernet, Serial, I/O, Fieldbus conversion, and other industrial protocols G527/G528 Security Gateway with LTE Cat 13 or 5G, built-in cryptographic secure element and PSE-PoE G528 Transportation Gateway (coming soon) with LTE Cat 4, GNSS, accelerometer, CAN Bus reading, and other tracking features Lantronix G520-series specifications: SoC – ARM926EJ-S-based processor running at 600 MHz with 32 KB instruction cache and 32KB data cache System Memory – 256MB DDR2 SDRAM Storage – 8MB SPI flash for OS,  256MB parallel NAND flash, MicroSD slot, or USB flash drive […]

JetHome JetHub D1 is a Linux automation controller based on Amlogic A113X SoC

JetHub D1 & H1 automation controllers

I discovered JetHome Jethub D1 and Jethub H1 Linux automation controller based on respectively Amlogic A113X and S905X SoCs in Linux 5.16 changelog, as both platforms got upstreamed to mainline Linux. I had never heard of JetHome, a Russian company based in St. Petersburg, nor their products before. Both Jethub D1 & H1 will run either an Armbian-built Ubuntu operating system or Home Assistant Operating System (formerly HassOS), and support Home Assistant (Z2M), Home Assistant (ZHA), and ZIgbee2MQTT. Jethub H1 looks like a TV box with a Zigbee module, while Jethub D1 is a DIN Rail automation controller with plenty of I/Os. Let’s focus on the latter. JetHub D1 specifications: SoC – Amlogic A113x quad-core Cortex A53 processor @ up to 1.5 GHz System Memory / Storage configurations 512MB RAM and 8 GB flash 1GB RAM and 16 GB eMMC flash Connectivity 10/100M Ethernet RJ45 port Dual-band WiFi 5 and […]

$65 dual Wi-Fi HaLow gateway kit extends network range by hundreds of meters

STK-AH9066 802.11ah gateway

I’m starting to better understand what Wi-Fi HaLow (aka 802.11ah) is for, after seeing a kit with two WiFI HaLow gateways used to wirelessly extend the range of Ethernet connected nodes on the LAN, including IP cameras, to several hundred meters, far more than your typical WiFi repeater, but at the cost of a lower bitrate. Yesterday, I wrote about Halo TD-XPAH, the first easily procurable 802.11ah WiFi HaLow development board I had seen, since the introduction of the new standard in 2014. But I was told another lower-cost HaLow board had been available for a few months on Alibaba, and while I failed to find it on Aliexpress, I discovered a pack with two WiFi HaLow to Ethernet gateway that could easily help extend the range of WiFi nodes like security cameras and selling for about $65 shipped. STK-AH9066 WiFi HaLow gateway specifications: Wireless 802.11ah Wi-Fi HaLow standard 902-930MHz […]
