So it's build with native android ble APIs in android java, esp32 with bludroid APIs. Used custom service uuid and characteristics uuid.
Note for some specific param like battery, heart rate, temp Bluetooth has assigned specific UUIds used in general.

[Tejas Birute @BiruteTejas]

So just build quick app+hardware for small building scale model where room by room lights are controlled here for example blue led later in building lights with relay.
2d room layout with button overlap.
Wireless control with Bluetooth BLE. At top-left green dot is conn-status.

DEF CON 32 - Anyone can hack IoT- Beginner's Guide to Hacking Your First IoT Device by Andrew Bellini @d1gitalandrew

TLDR:- An Walkthrough covering the methodology, tools, tactics and a <$100 toolkit to find your first IoT vulnerability.

@JeySG23 Actually gnss/gps is inside simcomA7672s module I think it's unicore ufirebird chip. Check this detailed teardown https://t.co/OGOJE6ZF48

How do you know the moment your asset leaves a safe zone?
so quickly built a geofence alert prototype: draw a box on ThingsBoard, and any device crossing out will triggers a live alert — clears automatically when it's back inside.
Thingboard ai-feature is very helpful incase.

@astrobase_space Super excited.. again red this tho 😛

A good reminder that "it connects to the internet" and "it's secure" are very different things. #Firmware #IoT #EmbeddedEngineering #zephyr #secure

[Tejas Birute @BiruteTejas]

Debugging my Zephyr RTOS + ESP32 firmware, I ran a Wireshark capture on the traffic.
Plain HTTP requests? Every byte of the response sitting there in the clear.
Switch to HTTPS with proper TLS certs? Just noise to an eavesdropper. i can check where connects tho..

@DJSnM yikes the ship do maneuver not starlink sat..

[Tejas Birute @BiruteTejas]

Lesson: Start simple, verify each layer, then build up. 🚀

[Tejas Birute @BiruteTejas]

Working on Zephyr RTOS , Claude build the project got into multiple issues with library, mbedtls errors and hallucinating.. then start with example project on http -> https -> certificates debugging with openssl -> fix proj.conf and now its working...

@SkyrootA Engineering in detail... great slomo : )

[SpaceX @SpaceX]

Watch Starship's thirteenth flight test https://t.co/qkYYJiX24h

[Tejas Birute @BiruteTejas]

@PittieAditya is this open for all or for industry people only?

[Tejas Birute @BiruteTejas]

@SkyrootA Hardware is hard Still ! Test cases need to pass and simulation done to make this happens is pure magic! Great Team all @SkyrootA

[Skyroot Aerospace @SkyrootA]

ORBIT ACHIEVED. 🚀

Vikram-1 Test Flight-1 has reached orbit. India's first privately developed orbital rocket has completed its final burn and injected its payloads into a ~450 km orbit, making India the third country in the world with private orbital launch capability.

History is made. 🇮🇳

[SpaceX @SpaceX]

The path to launch is filled with obstacles and success is only possible through the tireless efforts of many working together towards a common goal. “Critical Path” continues the ongoing Starship series, following SpaceX engineers through the final days before launch of the first Starship V3 and the challenges that come with development of the world’s most powerful and fully reusable rocket.

@SpantsUK @OpenSkyNetwork @M5Stack oh! forget to mention here mentioned in repo
just added what i found missing actually, Thanx : )
https://t.co/wQfO99BsFM

[Tejas Birute @BiruteTejas]

Used api @OpenSkyNetwork encoder dial from @M5Stack
Vibe coded and
pretty much what I wanted
Zoom in/out , plane vector and radar sweep
What else to add...🧐

[Tejas Birute @BiruteTejas]

@ClWZN5Iu2icXq1K @OpenSkyNetwork @M5Stack Nice idea sure will think of making starmap on screen and iss/sat overlay..
