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. EsPiFF board specifications: Wireless module – ESP32-WROVER module with dual-core ESP32-D0WDQ6 microcontroller with 2.4 GHz WiFi 4 and Bluetooth, 8 MB PSRAM and 16 MB flash Co-processor – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 16MB flash used to emulate the Raspberry Pi’s GPIOs on the 40-pin header Additional storage 2 KB of fast FRAM for permanent storage of process data. (faster […]

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 […]
