Hello, i have to do broadcast the sensor data from raspberry pi to local pc using BLE and python as language. but i don't have any idea. i did some R&D but did not get it. please help me to do this. i hope you help me. thank you in advance.
Great video, my goal is to learn and get good at BLE / NRF tech right now. Already did #1-#4 and read the first book, going to buy yours! I’ve only considered using Nordic chips so far. As a beginner should I stick to learning Nordic/NRF Connect / Zephyr, or should I checkout some other chips? Nordic is #1 for BLE chips, no? Who would be #2?
I can't really judge who's #1 and #2 :) But I can tell you I've mostly worked with both Nordic and Silicon Labs and I've enjoyed working with both of these. Don't forget about module makers as well (I should've mentioned this in the video), as they can make working with some of the chipsets even easier by adding their "special sauce".
You can track market share via the Bluetooth certifications out there, and Nordic has roughly 60% of those new certs so yes they are #1! Mohammad is right, Silicon Labs is also a terrific option -- their strength is that they develop chips AND certified modules which make it easier / cheaper to get to market with a lower volume project. If you're building
Something I don't get about the Windows and Android apps: how come there's not a sniffer app that can show what data is being sent and received over the various BLE services (using the standard built-in BLE compatible SoCs)? All the apps seem to do is just show what BLE devices are advertising what services and characteristics. Am I missing something? Do I really need to buy a sniffer or dev-kit to see what data is going back and forth between my laptop and a BLE device connected/broadcasting to it?
You can check out capturing the HCI Logs on Android to see exactly what's being sent through the BLE chipset. source.android.com/devices/bluetooth/verifying_debugging fte.com/WebHelpII/BPA600/Content/Documentation/WhitePapers/BPA600/Encryption/GettingAndroidLinkKey/RetrievingHCIlog.htm On Windows, I'm not very familiar, but you may find something helpful in this page: docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/ The use of an independent device/sniffer has its advantages such as minimum interference with the application and capturing the packets in real time.

Thank you for sharing your book!
Hey I also worked in the same period when you started, I was working on fitness tracker, I can understand your pain at that time
Job well done Mohammed, thank you.
Amazing tutorial. Please upload more videos
Really awesome ❤
Really informative video!
Interesting, I worked in a sponsorship with a company designing a BLE door lock. Were they based in Orlando by chance? Haha.
The company I worked with was Allegion (Schlage brand). I think they did have an office in FL but I was involved with the office in Indianapolis

I'm trying to do something similar, did you succeed?
Thanks for this video. Please update links.
Thanks, Casey. Which link(s) exactly are not working?

Dear Mohammad, isn't it possible to add English subtitles?
Yes, it is. I'll look into it

Yes. That was the old version at the time of recording. Yes the new edition is not free like the original.
how to get old free version of the book ?@@NovelBits
