M5Stack Core2: OWON Multimeter & Atorch DC Load in Home Assistant

Wie auf meinem Blog bereits mehrfach zur Heimautomatisierung und Labor-Elektronik geschrieben, setze ich konsequent auf offene, lokal lauffähige Stacks. Mein Ziel war immer, Messwerte meines Equipment direkt und ohne Cloud-Abhängigkeit in Home Assistant zu haben. Ursprünglich lief der OWON B35T auf einem M5Stack Core 1, wo ich den Original-Sketch als eigenständiges Zweitdisplay am Basteltisch im Einsatz hatte. Später folgte ein zweites, separates ESPHome-Gerät, das mit der Firmware von […]

I used #Bluetooth / #BLE as a short-range stand-in for #LoRa to test #Reticulum mesh behavior with #TBeamSupreme units.

The RSSI graph worked: carry two units away from a base pair, watch signal strength decay, disappear, then recover on return.

The GPS trace? Woeful. Useful lesson: RSSI test succeeded; urban T-Beam GPS precision did not.

PolyCast5 – An ESP32-C5 multi-tool remote with dual-band WiFi 6, BLE, ESP-NOW, LoRa, and Infrared Tx/Rx (Crowdfunding)

PolyCast5 is a portable, hackable ESP32-C5-based multi-tool remote to control devices through five different core wireless technologies: WiFi 6, Bluetooth LE, ESP-NOW, LoRa, and infrared Tx/Rx. The all-in-one controller can be used for cybersecurity work, a standard IR learning remote control, a voice-enabled password manager, a robotic arm controller, an AI keyboard using the built-in microphone and Bluetooth connectivity, a long-range LoRa remote control, DIY electronics projects through a 4-pin GPIO header, and more. PolyCast5 specifications: Wireless module – ESP32-C5-WROOM-1 SoC – ESP32-C5 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the main processor for power-sensitive applications Memory – 384 KB SRAM on-chip, 8MB PSRAM Storage – 320 KB ROM Wireless Connectivity Dual-band (2.4GHz/5 GHz) 802.11ax WiFi 6, with 802.11b/g/n WiFi 4 standard fallback Bluetooth 5.0 Low Energy (LE) 802.15.4 radio for Zigbee 3.0 and Thread 1.3 (note: support not

WCH BLE Analyzer Pro USB Bluetooth LE sniffer gains Linux software with Wireshark (pcap) support

Last November, we wrote about the WCH BLE Analyzer Pro, an inexpensive (~$20) USB Bluetooth LE sniffer and analyzer, which looked useful and good value for reverse engineering and debugging. One downside is that the WCH BLE Analyzer software was only made for Windows 7 to 11, but Xecaz decided to look into it and reverse-engineered the USB protocol to write Linux software using libusb that outputs a standard pcap compatible with popular tools such as Wireshark, or as he puts it: "WinChipHead forgot to ship a Linux driver. We forgot to ask permission." As a reminder, the BLE Analyzer Pro features three CH582F Bluetooth LE RISC-V microcontrollers and a CH334 USB hub, supports Bluetooth Low Energy (BLE) 4.0/4.2/5.0, and connects to the host through its USB-C port. The Linux "driver" for the BLE Analyzer Pro tool can be found on GitHub. Building and installing the software is quick and

Does anyone know a good alternative to #RoomAssistant?
I don't want to get #mmWave shit everywhere. I just want to use #BLE if possible.

Two $17 Raspberry Pi Zero 2 W boards exchanging encrypted poems over #Reticulum using Bluetooth only -- no LoRa hat, no extra radio, no carrier network.

A small-board demo of #microReticulum in C++ with BLE as the link layer. Cheap hardware, built-in radios, real packets, real timing, real tinkering.

#RaspberryPi #PiZero2W #Bluetooth #BLE #Linux #SBC #Maker #SmallBoardComputers

Skipping the #TBeamSupreme for this test: two bare #RaspberryPiZero2W boards running #microReticulum with my BLE interface, each sending poetry to the other over their built-in Bluetooth radios.

Two $17 SBCs, 8.8 MB builds, fully secure Reticulum link, and ambidextrous roles: start both, and they decide who is client/server.

#Bluetooth #BLE #Reticulum #RaspberryPi #MeshNetworking

Milestone: Torlando’s Python BLE Reticulum protocol behavior has now been partially distilled into a C++ protocol/session core and field-tested between two Raspberry Pi Zero 2Ws. The test moved the full U.S. Constitution both directions over Reticulum using BLE, with C++ fragmentation/session backends confirmed.

Делаем любимую механику беспроводной: BLE-адаптер для Kingston HyperX Alloy FPS на базе Raspberry Pi Pico W

Продолжаю рассказывать о своём опыте создания BLE адаптера для USB-клавиатуры, которым уже пользуюсь каждый день. Собранный ранее на макетной плате адаптер с подключённым pico debug был хорош тем, что можно было экспериментировать, набираться опыта, но пользоваться таким адаптером как устройством неудобно: нет корпуса и нет автономного питания. В комментариях к прошлой статье читатели упоминали, что китайцы продают адаптеры, по функционалу похожие на мой, но пользоваться такими адаптерами также неудобно. C хостом действительно беспроводной канал, а вот кипу проводов к самому адаптеру никто не отменял. Стремление к универсальности часто приводит к неудобным решениям, поэтому я сосредоточился на своей клавиатуре Kingston HyperX Alloy.
