Built a Bluetooth BLE scanner + device finder app for iPhone after years of working on BLE SDKs

So I built:
NovyBLEPlatform

Current features:
• BLE device scanning
• Signal strength monitoring (RSSI)
• Nearby device detection
• Device details/services
• Real-time updates
• Bluetooth diagnostics utilities

The goal is to keep improving it into a useful Bluetooth toolkit for:

• developers
• IoT testing
• BLE debugging
• finding nearby devices
• AirPods/watch utilities later

Would genuinely love feedback from people who work with BLE regularly because iOS Bluetooth behavior can get pretty wild sometimes 😅

Hi everyone,

I’m looking for some honest feedback on a few Electrical/STEM teaching resources I’ve recently made.

At this stage I’m genuinely not trying to sell anything or promote products — I mainly want feedback before I spend more time creating additional resources.

One of the resources is based around Ohm’s Law and includes:

• visual learning materials/posters
• a simple Ohm’s Law simulator that runs from a basic HTML file (no software installs or setup required)

My background is automotive electrical and vocational teaching, and I’ve been trying to create resources that are modern, visual, technically accurate, and easier for students/apprentices to understand.

I’d really appreciate feedback on things like:

• visual design/readability
• usefulness in class
• clarity of explanations
• whether the simulator is actually engaging/helpful
• anything you think could be improved

If this type of post is allowed here, I’d really appreciate any feedback or suggestions.

Thanks!

I am looking for litterature for beginners with accompanied problems and conclusions like you have in school so that I can study on my own. I allready have one edition of "The Art of Electronics" but i need something that's more like going to school as i have a really hard time concentrating for more than 15-20 minutes when reading and often need to reread a page a couple of times as my thoughts wander about. I would love some sort of set with experiments, facts, conclusions so that I can see if i got it correct and what not. I have tons of components and protoboards/breadboards and so on, an i am building stuff from schematics that works, but that way I don't get to know how to calculate the component values, and no real understanding of curcuits. It's more like cooking food after a recepie where yeah you make the food but you wont undestand why you need certain spices, Heat levels and what goes with what, if you understand what i mean.
