EdgeBox-ESP-100 – An ESP32-S3 industrial controller with RS485, CAN Bus, DIO, 4G LTE, and more

We’ve previously covered the EdgeBox-RPi4 industrial controller powered by a Raspberry Pi Compute Module 4 and plenty of I/Os such as RS485, RS232, digital inputs and outputs, and connectivity options such as Gigabit Ethernet, WiFi 5, Bluetooth 5, and 4G LTE. But if you don’t quite need the power of a Linux controller, the EdgeBox-ESP-100 industrial edge controller based on an ESP32-S3 dual-core WiFi and Bluetooth microcontroller and offering a similar set of features, albeit with twists, may be an interesting option. EdgeBox-ESP-100 specifications: Microcontroller – Espressif Systems ESP32-S3 dual-core Tensilica LX7 microcontroller @ 240 MHz with AI vector instructions, 512KB RAM Memory – 8MB PSRAM Storage – 16MB Flash Network connectivity 10/100M Ethernet RJ45 port 2.4 GHz WiFi 4 and Bluetooth 5.0 LE via ESP32-S3 4G LTE cellular via SIMCom A7670G LTE Cat 1 module Optional support for LoRa (replaces the A7670G module) Serial & I/Os via terminal blocks […]

Pinecil V2 Bluetooth LE soldering iron gets a web interface

It’s now possible to make use of the Pinecil V2 soldering iron‘s Bluetooth LE connectivity through a web-based interface used to monitor and/or set the temperature and power of the RISC-V soldering iron. When the Pinecil V2 soldering iron was launched with a Bouffalo Lab BL706 RISC-V Bluetooth microcontroller last summer, we were told there were main potential cases to make use of the Bluetooth LE features: OTA firmware upgrade and remote telemetry and control. The latter is now being taken care of by Joric who has written a web application to visualize telemetry data and even control the temperature of the soldering iron. To be able to use the Bluetooth features, you’ll first need to install the latest Pinecil V2 firmware with blisp flashing utility before going to https://joric.github.io/pinecil to pair your soldering iron as explained in the wiki. Note the implementation relies on the Web Bluetooth API which […]

EsPiFF board combines ESP32 module with RP2040 MCU in the Raspberry Pi 4 form factor (Crowdfunding)

The EsPiFF board may look like a Raspberry Pi 4 Linux SBC but it is equipped with an ESP32-WROVER WiFi and Bluetooth module together with a Raspberry Pi RP2040 microcontroller that acts as a co-processor. The goal here is to provide a Raspberry Pi 4 replacement for applications that require higher reliability and even 24/7 operation without necessarily needing the processing power and multimedia capabilities of the Broadcom BCM2711 Arm processor found in the Pi or the versatility of a Linux operating system.

Bluetooth LE to support 6 GHz frequency band

So far, the popular Bluetooth wireless communication protocol would only rely on the 2.4 GHz frequency band, but this may change in the future, as the Bluetooth Special Interest Group (SIG) has recently announced a new “specification development project” to add the 6 GHz frequency band to Bluetooth LE. Mark Powell, CEO of the Bluetooth SIG “explains” the move: The Bluetooth SIG community is constantly evolving the technology to meet ever expanding market demands for wireless communications. Expanding into the 6 GHz spectrum band will ensure the community can continue to make the enhancements necessary to pave the way for the next twenty years of Bluetooth innovation. I get it that’s a long-term move, but it does not explain exactly why the additional 6 GHz (and 5 GHz) bands may be necessary. I’d just suspect as more devices such as BLE sensors get more widely added that adds to the […]

Giveaway Week – GL.iNet GL-S10 BLE to MQTT Gateway

The sixth prize of this year’s Giveaway Week will be GL.iNET GL-S10 BLE to MQTT gateway based on the ESP32 microcontroller and offering Ethernet, WiFi, and Bluetooth LE connectivity. The gateway is used to gather data from Bluetooth LE devices such as beacons and can be used in warehouses, shopping malls, airports, exhibition halls, tourist attractions, etc… for personnel management, asset management, environmental monitoring, indoor navigation, and more. I reviewed the ESP32-based BLE to MQTT gateway with the provided BLE beacon at the end of last year using MQTT X open-source client and the GL-S10 Tool App for Android. It allowed me to send commands through MQTT topics, for example, to set or retrieve the beacon’s (WiFi) configuration, and receive the data through MQTT subscriptions. Some of the data include the MAC address, RSSI, ad (Broadcast data advData), and a timestamp. It took some effort to get it working, but […]
