Microcontrollers for iOS Developers: Part 3 - CoreBluetooth - BLE

Second video in a series of streams where we take a look at how you can use your apps to control bluetooth and wifi enabled devices.

Not just any device, but ones you have full control over. We'll take a look at writing firmware for these devices, connecting sensors, and streaming that information back to an app that we create.

This third video covers building a small app to read data from a connected piece of bluetooth hardware.

Working with hardware at this level is super easy. If you already have a programmers mindset, it's not that different from programming an iPhone.

After this series you should have enough experience to control other items in your home, or even create your own hardware products that have a paired app!

This is the best video I've ever seen; it truly captures how we, as programmers, typically work. I was searching for BLE on iOS, and this was the only video across YouTube that explained how to handle it. Thank you for your channel, the content is pure gold.

Great video. Would love to see a continuation with bi-directional communication with a device (locking, multiple packets, etc.)

This video is GOLD. 🔥Thank you so much, I was looking for this for quite sometime. Thank you for sharing 🙌🏽

I love this kind of videos. SUPER educational. I've been trying to work with BLE for medical devices on iOS, and it was quite fun to work with (albeit challenging). I wish to see some architectural design choices in the next part of the series!

This is great tutorial. I follow this series and make own water system for plants using ESP32 for my wife, she is very surprise for that. Thanks you so much.

Loved it ❤, Real life development is not scripted.

Hi, I really like your streams related to embedded devices and IOS. Have you planned to continue the series ? I would really like to see one with an integration between an IOS app and the Raspberry PICO W (which supports bluetooth since a few weeks) with a micropyhton app running on the pico

Hi, Is there someway we can connect an iPad to a PC using BLE and send over files from the iPad to the PC using that connection?

[andrewmuniz]

Hey, are you ever going to make the project you mentioned where you turn on and off a LED from an app? I have a simple two-motor robot I created and a Swift app that acts as a controller to make it go forward, backward, left, and right. I just cant figure out how to connect them.

Did you try Bluetooth auto pairing for this microcontroller to iPhone?

[maclagat]

What is the program you are using to create the ios app?

Hi I am looking for an IOS BLE RC App to control a car, any advice? Thx.

My app is just stuck on scanning: 0. Everything else works but you didn't show how you connected the esp with your phone. Did you use regular bluetooth or did you download the app on your iphone as well? I am using ipad, would that cause a difference?
