My apologies for the delay in getting this video out, I started recording it over a month ago but had an accident that delayed finishing it. If you want all the gory details you can read about it in the Community section of the channel. The scenes with my face in this video were recorded the day before my accident, the voiceovers for the animations, and the demos were mostly recorded recently. The accident knocked out my two front teeth and required stitches on my lips, and as a result, my voice has changed, and I am finding it difficult to pronounce many words. I apologize if I sound a bit like Elmer Fudd is certain sections! Hopefully, the next video will be out shortly, and I hope you enjoy this one! Bill
You sound fine Bill. Glad you're back in the saddle. Great explanation on ESP32 Bluetooth Classic & BLE. The asynchronous nature of BLE operations get kind of tricky when you start adding multiple services and/or characteristics. I found this out when I created my very first Android mobile app that connects to a XIAO ESP32S3 via BLE. Perhaps handling such a use case could be the topic of a follow-up video.
Another fantastic tutorial breaking down a complex subject! Thank you. Your Audio I2S video and forum article were instrumental in me completing a successful Internet Clock Radio Project including making the stereo mod to the MAX amplifier modules. Thank you!
Glad to see you back and looking well. A thought for you - whenever you have an accident its always tempting to think "If only I hadn't done this or that" the other side of that thinking is perhaps you avoided a much worse situation by having this accident. Best not to dwell on it. Cheers
Very sorry to hear about the unexpected family issues via your recent newsletter. These came on top of your accident in April. Family and health come first, Dronebot Workshop content can wait. We will still all be here and, as you are always saying to us, take care and stay safe.
I really appreciate the video; this talks about many of the issues I am wrestling with around Bluetooth. You do an excellent job providing practical, useful material. If I can add a relatively unimportant note about my (presumable) Scandinavian ancestor, the "Har" - Harald is pronounced like "Car". "Harr-alld", instead of "Hair-old"
Great video. Provides a excellent knowledge base that can be built upon as you dive deeper. Very glad you are mending well and your voice sounded fine.
Thank you great work. Hope you recovered well. Your video explains things from the basics and I found my solutions from your detailed explanations. I thought any Bluetooth codes would work and I now know I need BLE related codes because of my ESP32-C chip.
It's a shame more of the latest devices no longer support BT Classic as I have always found that to be really useful, especially as a simple wireless UART. Such a port makes an excellent debugging tool IMO
Very interesting video! I want to learn more about the ESP32-H series and its Bluetooth capabilities. I intend to convert my electric violin into wireless with Bluetooth 5.2 BLE and LC3 codec. Has anyone experience with the software implementation out there?
I don’t know whether it’s fate or chance, every time I’m working on a diy project you come out with a very useful information, yes this one is still hard for me but if i elaborate I’m sure you can help me as I’m being a good student. I’ve build a diy speaker and a woofer, I want the two to communicate wirelessly, well I’m not good at coding but I’m happy with my speaker output as I managed to embed a DSP on its output. I want to make it more juice and make it trade blows with other expensive known speakers like JBL and Bose that’s why I want to find a way to program an ESP32 to receive and transmit data from the speaker to the woofer and get rid of the wires connecting the two devices, the woofer is separately amplified and so is the speaker that means both devices are powered but the wireless connection is the only challenge I still have. Best regards and thanks
BLE usually comes on top of a low power application (battery, energy harvesting)... I hear ESPs drain energy, especially when the radio is turned on (low energy or not). Nordic or silicon labs chips are the way to go for low power wireless application... Nice video though!
Thank you for excellent video. I am going to use BLE for data streaming. Not audio, but transfer of heart signals. Basically I need to transfer 100 bytes per second. Is BLE a good replacement over classic BT to reduce power consumption ?
Hi, i am beginner to esp32. I am trying to transfer file to sd card in esp32 development board using react native programming. is there any process to do so without any ftp or TCP or web server. please do guide me in this project. Thanks in advance.
Thank you for producing an article for this - I like to read things and absorb them - and also providing it in PDF format. Outstanding content + helpfulness. Legend! Hope you are continuing to heal up.
Great to see you Bill, welcome back. Hopeful that you will fully recover soon. I hope your mother also recovered. No hurry on the videos, take care of yourself and your mother.
Very nice and simple explaining for the BT systems. Thank you very much. I enjoy all your videos and your great and simple but technical explanation. Very good!!! I will keep watching all your videos.
I think the BLE library stopped working after the last esp32 update. There is no problem creating the server, but the client code gives a "Stack smashing protect failure!" error and reboots.
Any thoughts what would be involved in writing an ESP32 application, that takes data from the uart, and passes it wirelessly either via bluetooth (SPP) or via Wifi? For Wifi, I imagine the ESP32 could act as a web server (TCP) and display the RS232 data, but maybe there's a UDP way it could send data to a PC on the same network? I imagine, if the receiving application (mobile or PC) is written in the flutter framework, it could display the RS232 data with style!
Loved the overview & the details. What about some videos on Zigbee and using Amazon Echo (Alexa) for connecting and controlling projects? Voice controlled projects, yeah!
I saw the title and thought "must watch that" ... The video started and immediately thought "oh it's this guy again" and stopped what I was doing to watch properly. Loving your videos, thanks

Got here by accident, but i'm glad I did! What a wonderful MASTERCLASS you have just presented on this video, I learned A LOT. Thank you soooooo much. I'm subscribing to your channel right now!!
Good video, something to keep in mind is that although the esp32 supports BLE the low power part is not implemented meaning it will work but won't be low energy, at least in arduino with the current libraries
