It adds a new mDNS-based server stack, smarter handling of untrusted networks, and improved device discoverability. The article reports a 32% improvement in auto-connection success rates and a 66% increase in connection speeds for 90% of connections. ### Source excerpt Posted by Steven Jenkins, Product Manager, Sherif Eid, Senior Software Engineer, and Fabien Sanglard, Staff Software Engineer, Android Studio Wireless debugging on Android is now faster, more reliable, and easier to set up than ever. With ADB Wi-Fi 2.0, we've introduced a new server stack and smarter network handling to directly address developer feedback around usability gaps. How ADB Wi-Fi 2.0 Improves Wireless Debugging To ensure ADB Wi-Fi 2.0 is even more reliable, we reworked all three core components of the stack: the adb server, the adbd daemon, and Android Studio. Here are the new features: A new server stack (adb): Previously, wireless device connections would sever when network configurations changed or devices were turned off. This meant that connections would drop for common occurrences. With our new mDNS stack, we've replaced both Bonjour and legacy mDNS so that your wireless devices more reliably stay connected as you go about your day. Smarter network handling (adbd): Previously, the workstation's mDNS client would sporadically drop services. Now, the daemon automatically turns off ADB Wi-Fi when it detects an untrusted network and re-enables itself once running on a user-allowed network. Improved discoverability in Android Studio: Previously, Wi-Fi pairing was difficult to find. Now, you simply enable wireless debugging on your phone and it will show in Android Studio's Device Manager. With ADB Wi-Fi 2.0, auto-connection success rates improved by 32% and connection speeds increased by 66% for 90% of connections. Getting Started You can use ADB Wi-Fi 2.0 on your phone, tablet, Wear OS, and TV. Here's how to get started: Update to Android 17, Android SDK Platform-Tools 37.0.0, and Android Studio Quail 3 or later. Ensure your workstation and your Android device are connected to the same Wi-Fi network. On your device, navigate to Developer Options and enable Wireless debugging. Open the Android Studio Device Manager and click the pair over Wi-Fi icon.

Developers must ensure the radios are enabled and notify users when manual activation is required. The change is scheduled for late 2026. ### Source excerpt Posted by Wei Wang, Engineering Manager, Android BeTo User privacy and transparency are core to the Android experience. To better align with these principles, we are updating the default behavior of the Nearby Connections API regarding how it interacts with device radios. What is changing? Previously, the Nearby Connections API could automatically toggle Wi-Fi and Bluetooth radios ON to facilitate connections without explicit user intervention. Moving forward, the API will no longer automatically enable these radios for 1P and 3P applications. What this means for developers If your app relies on Nearby Connections, you will need to update your implementation to account for these changes: Manual Radio Management: You must ensure that the necessary radios (Wi-Fi or Bluetooth) are enabled before initiating Nearby Connections tasks. User Notification: If the required radios are disabled, your app must now inform the user and request that they enable them manually. The API will no longer programmatically turn them on for you. Timing These changes are scheduled to take effect in late 2026. We recommend reviewing your connection workflows now to ensure a seamless transition for your users. ## NuttX Web Panel: A self-hosted web interface for NuttX DevFeed: [NuttX Web Panel: A self-hosted web interface for NuttX]() Original publisher: [Read original article]() Author: John Lee Published: 2026-06-29T00:00:00Z Content type: tutorial Language: en Sources: [Blog on Developer Portal]() Topics: [NuttX](), [Self-hosted](), [web applications](), [Python](), [WebSocket](), [Command-line interface](), [Monitoring]() Tags: [apache](), [blog](), [esp32-p4](), [monitoring](), [nuttx](), [posix](), [python](), [self-hosted](), [terminal](), [web](), [web-interface](), [wi-fi]() ### AI overview NuttX Web Panel is a self-hosted web interface that runs on a NuttX device.

The article describes issues including weak firmware-update verification, unrestricted login attempts, an unauthenticated file-execution service, and command execution as root. ### Source excerpt Исследователи компании Eclypsium в свежем отчете сообщают об обнаружении целого набора уязвимостей в четырех пользовательских адаптерах IP-KVM. Такие адаптеры, как следует из названия, позволяют удаленно управлять компьютером, эмулируя клавиатуру, мышь и внешний дисплей. Компрометация таких адаптеров, соответственно, позволяет полностью перехватить контроль над управляемым устройством. В Eclypsium справедливо предположили, что дешевые (от 30 до 100 долларов) пользовательские устройства будут хуже защищены, чем аналогичные решения для применения в корпоративных сетях.

It argues that this can reduce captive-portal logins, work around single-device Wi-Fi plans, restore local device discovery, and, in some setups, route connected devices through Tailscale. ### Source excerpt Ubiquiti announced a new travel router. Much of the internet is excited. So am I. Then I tried to remember the last time I actually needed a travel router. You see, Android has supported a feature I'll call Wi-Fi sharing for years.1 Your phone connects to an existing Wi-Fi network and re-shares it as a hotspot. This might sound like a regular hotspot feature that most phones (including the iPhone) come with. But it's not. iPhones can share mobile data. They can't re-share a Wi-Fi connection as a hotspot. Wi-Fi sharing Your phone connects to Wi-Fi, and then re-shares that same Wi-Fi as a hotspot. This is different from typical hotspot functionality where the phone shares its mobile data connection (vs Wi-Fi). Neat trick, but why bother? Can't you just connect each device to Wi-Fi? Avoid signing every device into a captive Wi-Fi portal ## Captive portals are annoying when you're carrying multiple devices. I typically travel with 3-4 devices that want internet. Signing each one in, every time, gets old fast. Some devices are worse: Chromecast and Fire TV sticks are particularly painful to get past captive portals. If everything connects to your hotspot, you only deal with the portal once.2 Work around "one device at a time" Wi-Fi plans ## On a plane, I sometimes want both my laptop and phone online. Some paid Wi-Fi plans only allow one device at a time. Unless you're ok paying twice, Wi-Fi sharing is simpler.3 Hotels and conference centers do the same: sign-in plus device limits. Wi-Fi sharing works around it. Fix "devices can't see each other" networking ## This one is less obvious, but common in hotels and conference Wi-Fi: your devices have internet, but they can't see each other locally. Chromecast (or printers) won't show up as a cast target because it doesn't appear on the network. That's usually client/AP isolation.4 Put your devices on your phone's hotspot, and local discovery usually works again. Secure networking with a Tailscale setup ## This is slightly adv ## Sunsetting spoton: Android 16 killed the hotspot toggle trick DevFeed: [Sunsetting spoton: Android 16 killed the hotspot toggle trick]() Original publisher: [Read original article]() Author: Marco Gomiero Published: 2025-12-16T00:00:00Z Content type: article Language: en Sources: [Posts on Marco Gomiero]() Topics: [Android](), [Wi-Fi](), [API]() Tags: [android](), [android-16](), [api](), [hotspot](), [wi-fi]() ### AI overview The author explains why the spoton Wear OS and companion phone app is being sunset. The app used reflection to call hidden Android tethering APIs and let users toggle a phone hotspot from a watch. Android 16 moved the relevant methods and added a permission limited to system apps, preventing the approach from working for a normal Play Store app. ### Source excerpt spoton is getting sunset. I started this project because I had a very specific (and very lazy) problem: I wanted to enable my phone hotspot without taking my phone out of my pocket. I do it often when I'm travelling or working somewhere without stable Wi-Fi, and every time it was the same ritual: unlock phone, quick settings, find the hotspot tile, toggle, put phone away. At some point, I thought: "This should be a button on my wrist." ## Optimizing RAM Usage on ESP32-C2 DevFeed: [Optimizing RAM Usage on ESP32-C2]() Original publisher: [Read original article]() Author: John Lee Published: 2025-11-28T00:00:00Z Content type: tutorial Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32](), [ESP-IDF](), [Optimization]() Tags: [ble](), [blog](), [esp-idf](), [esp32](), [esp32-c2](), [how-to](), [memory-management](), [memory-optimization](), [optimization](), [practitioner](), [wi-fi]() ### AI overview This article explains how to optimize RAM usage on the ESP32-C2 with ESP-IDF v5.5.
