LEGO хаб Powered Up — передаём и получаем данные

Наборы LEGO с электрикой уже давно перестали быть просто игрушкой. Современная серия устройств Powered Up — это небольшая модульная робототехническая платформа: smart-устройства, моторы, датчики, подсветка, управляемые по Bluetooth, с возможностью программирования поведения моделей, что ранее было доступно только в специализированных наборах (LEGO Mindstorms, Education). Как же получить данные из smart-устройства, ведь это открывает новые возможности по использованию LEGO наборов.

「ClickFixマルウェア攻撃で悪用された数十年前の「Finger」プロトコル」： #BLE
EPINGCOMPUTER

「数十年前から使われている「finger」コマンドが復活し、脅威の攻撃者はこのプロトコルを使用して、Windows デバイスで実行するリモートコマンドを取得しています。

かつて、 UnixおよびLinuxシステム上のローカルおよびリモートユーザーに関する情報を、後にWindowsに追加されたFingerプロトコルを介して取得するために、 fingerコマンドが使用されていました。現在でもサポートされていますが、数十年前の人気と比べると、現在ではほとんど使われていません。

実行されると、finger コマンドは、ログイン名、名前 (/etc/passwd に設定されている場合)、ホームディレクトリ、電話番号、最終ログイン、その他の詳細など、ユーザーに関する基本情報を返します。」

Woot, done with BLE receiving. Added some new commands to control it all.

Still need to actually test the KISS output and support transmit.

But its been running all day and seems pretty stable.

#MeshTNC #devlog #radio #ble #lora

Here I was thinking the KISS protocol support was going to be hard ✨

Actually this flew together, mostly bc @meph already did all the hard stuff on KISS handling.

So just check which output mode we're in and yeet the data at the BLE data KISS port.

#amateurradio #wardriving #ble #embeded #esp32 #devlog #MeshTNC

First things first, I want to make it so that the ASCII CSV output format for BLE packets roughly matches LoRa packets.

Every packet gets an arrival timestamp, type, RSSI and SNR values. Followed by whatever payload.

In the case of BLE packets there's also a 6 byte MAC so I slap that infront of the payload.

There's no SNR data for BLE so that's always 0.0. But the RSSI is good.

A developer's note on enabling BLE Transparent Transmission for the BT401 Dual-Mode Audio Bluetooth module.

Data Flow:

Your MCU can send any data (non-AT-commands) over UART, and it will be transparently transmitted via BLE.

Any data sent from a mobile app is forwarded directly to your MCU, The module itself won't process it, giving your application full control.

A Quick Guide to BLE Transparent Transmission on the BT401 Module

Hello Embedded C Programming,

Sharing a concise guide for anyone using or considering the BT401 Dual-Mode Audio Bluetooth Module in their projects.

Enabling BLE Transparent Transmission is simple but has two prerequisites:
🔹 The module must be connected by a BLE central device (e.g., LightBlue/nRF Connect app).
🔹 That central device must manually enable NOTIFY on the characteristic.

Key Insight for Developers:
🔹 Data from your MCU over UART is transparently transmitted via BLE, unless it's a valid AT command for the module itself.
🔹 All data from a phone app (even AT-like strings) is passed directly to your MCU. The module does not process AT commands from the phone side, giving your MCU full protocol control.

This makes the BT401 a versatile choice for projects requiring robust audio and reliable bidirectional data.

I'm curious to hear how others are using BLE data channels in their audio applications!

Unlocking BLE Transparency on the BT401 Audio Module

Engineers and developers, are you leveraging the full potential of your BT401 Bluetooth module?

A common question we get is: "How do I enable BLE Transparent Transmission?" The answer is straightforward, but requires two key steps:
1. An App Connection: The module must be connected by a BLE debugging app like LightBlue or nRF Connect.
2. Manual NOTIFY Enable: Crucially, the app must manually enable the NOTIFY property—a standard procedure for all BLE devices.

Once active, the BT401's BLE transparent transmission channel is available throughout its powered-on cycle. Here's the data flow:
🔹 MCU to Phone: Any UART data from your MCU (except valid AT commands) is transparently sent via BLE.
🔹 Phone to MCU: Any data sent from a mobile app (including strings that look like AT commands) is forwarded directly to your MCU, giving you complete control over the protocol.

This functionality works for both the DAC (analog audio) and I²S (digital audio) versions of the BT401.

Requires:
Connection from a BLE app (e.g., LightBlue)

1. Manually enabling NOTIFY.
2. Data from your MCU is sent via BLE; phone data goes straight to MCU. Perfect for custom IoT protocols.

A developer's note on enabling BLE Transparent Transmission for the BT401 Dual-Mode Audio Bluetooth module.

The feature is always on when powered, but needs two conditions to be met:
✔️ Condition 1: It must be connected by a BLE central device, like the LightBlue or nRF Connect app.
✔️ Condition 2: The NOTIFY property must be manually enabled within that app.

Data Flow:
🔹 Your MCU can send any data (non-AT-commands) over UART, and it will be transparently transmitted via BLE.
🔹 Any data sent from a mobile app is forwarded directly to your MCU, even if it looks like an AT command. The module itself won't process it, giving your application full control.

Auracast – Stand EUHA 2025
Herstellerstimmen und Praxisworkshop

Neben der künstlichen Intelligenz war das zweite heiße Thema auf der EUHA (dem europäischen Hörakustikkongress) die neue Bluetooth-Funktion Auracast. Auracast wurde in den letzten Jahren entwickelt, um energiearmes, hochqualitatives Audiostreaming auf mehrere Empfänger zu ermöglichen. Es wurde insbesondere zusammen mit Hörsystemherstellern entwickelt, so dass es auch für Hörgeräte funktioniert. Auf der EUHA 2025 habe ich mit allen großen Hörgeräteherstellern gesprochen, um herauszufinden, wie es um Auracast in ihren Produkten und um ihre Zukunftsplänen steht. Außerdem nahm ich an einem sehr interessanten Workshop zum Thema teil.

In order to try and use my #bluetooth #ble printer, I'm now having to (checks notes) find and set up my old macbook, with chromeos flex in order to record the bluetooth traffic because android truncates the packets?

All of this hampered by only finding the low power charge so need to charge the laptop before trying an OS install because there's the real risk of it drawing more power than the small charger can provide

All of this because the printer only works with an android app, and I want to print from... Not that

BLE allows configuring events intervals - a key factor for optimizing energy use. By tuning these intervals, it’s possible to cut power consumption even further, which is crucial for a charging-free smartwatch.
