Hello World! Firefly Zero is an in-development handheld game console that runs #wasm and supports #BLE multiplayer. It is written by @orsinium in #Rust, runs on #ESP32, and will be fully open source (both software and hardware).
We already have a working desktop emulator and are getting a Rust and #golang SDK ready for alpha testing. Sounds fun? Stay tuned!
I was going to take a peek at reverse engineering a cheap BLE sensor I nabbed, but it seems like recent versions of Android truncate the (G)ATT packets in btsnooz_hci.log. I'm gonna go ahead and guess Google's just kicked us in the shins for no reason and there's no way to reverse that?
I got a no-name thermal-print toy camera (named "Q5"), with no obvious tech specs to look for. Anybody got one and opened the case or reverse-engineered the app?
It has "wireless printing", where it shows a QR code pointing to https://www.pgyer.com/UNhf - with bloated YinTiBao apps for Android and iOS. It does not have WiFi, but appears as a #Bluetooth#BLE device named "BQ05".
Hacking BLE to Liberate your Exercise Equipment eg for the Domyos EL500 elliptical trainer
It’s a story we’ve heard many times before: if you want to get your data from the Domyos EL500 elliptical trainer, you need to use a proprietary smartphone application that talks to the device over Bluetooth Low-Energy (BLE). To add insult to injury, the only ...continues
No luck yet - dumping the firmware and also dumping the APP was not successful. Now ordered an #BLE sniffer (available from #Adafruit btw.) - #TrailCamera reverse engineering
Still no success - the #BLE sniffer shows me a CONNECT_IND packet and then nothing else. Encryption? If yes, it has to be a static key as there was never any key exchange between app and camera (the wifi key is "1234567890"). No idea on how to continue. #BluetoothLE
The absolute best part of the #BigEar project is that I can just buy random #BLE sensors and throw them anywhere. Security is such a joke (its just broadcast) but the threat model is "someone driving past might notice that my pool is warm." 🤷 🌡️
(I do mean REALLY anywhere though, within about 4 yards/houses in most directions, using zero equipment outside the main house. Later I'll waterproof one and try it on the fence..)
Y'all shouldn't be buying #oralb toothbrushes or really ANY #bluetooth bathroom scale. Just saying. (And yes, I can probably see your growroom sensor too.)
Any devs out there with #bluetooth or #ble reverse engineering experience with #android ? I'm trying to sort out how a device and phone are communicating, but seeing nothing in the NRF connect app. I used a basic sniffer on an esp32, which managed to pick up some additional devices providing GATT services while the device is communicating, but it's very difficult to parse the logs. I've decompiled the app APK, but I'm not sure how to add logging to it, then recompile it for side loading.
Présentation super sympa d'étudiants de Eurecom sur un cadenas BLE. Encore un de ces cadenas non-sécurisé by design, avec des démos 😁 #BLE#hacking#leHACK
Hm, seems like there are no #BLE#Audio or #LC3 codec supporting standalone transceivers yet. While there are already some "True Wireless" pods out there, I'd like to use my favorite in-ear pieces (connectable through #MMCX). Even FiiO doesn't have anything yet, it seems.
With the #Pixel#tablet out, my desire to get rid of my #phone altogether is up again.
Just give me a #Smartwatch that can work standalone, has telephony, Signal+Navigation+Audio Streaming, and I'll get rid of my phone. NFC Payment optional plus, but please using #GrapheneOS.
In my mind, the watch wouldn't even require any port (thus fully water proof) and would attach to a display-less "fitness bracelet" you could even wear while sleeping. At night, you detach it and put it on a night stand for wireless charging. By day, you re-attach it, it reverse-charges the bracelet.
Paired with #BLE Audio it'd be the perfect device for me. Can't really lose it, flush it down the toilet, don't need to figure out where to transport it (my pockets are even too small for Pixel 6a..., or nonexistent), or need to be worried about water.
Been working on something new and very cool - an IoT platform that doesn't rely on fixed connectivity to stay connected. Encourage you to check it out, docs and demo apps are out now, SDK will be available in a couple of weeks. Can't wait to see what you build on it - tell all your friends!
If you've noticed that #homeassistant/#esphome is bad with distances, I agree. It looks like the rule is "latest answer by a microsecond wins". This is a huge problem if you can ever be seen by more than one radio at once.
Instead, you can use this project to add a distance sensor to each radio and get the data you probably wanted to begin with. It doesn't scale, but I don't have that many cats..
