THIS METHOD IS OLD. NEW LIBRARIES ARE OUT THAT LET YOU DO THIS PROPERLY. WATCH THIS VIDEO TO LEARN HOW : ukposts.info/have/v-deo/iGCSpZh7cKuepXk.html

Hi, would you make a tutorial on how to send temperature sensor or soil moisture sensor data from one esp32 to other esp32 over wifi or any protocol ? it would be a great help to learn Thanks

@northshorepx 6 років тому

Brilliant solution to one way transmission. Thank you for a very funny and very informative video!

@inakiinchaurregui4848 5 років тому

Hi! Do you know if you can change the name of the bluetooth so that it appears as we want, when looking for it with another device?

@e_butcher 5 років тому

Hello. Would you make a video how to connect two ESP32 over BLE? Thank you.

bro can we send data throw phone to esp 32 but you have shown in this esp32 to phone plz help me bro thank you

@SimonEllwood 6 років тому

Good video, great to see how simple BLE can be. I hope full GATT support is available now however!

@LiveSparks 6 років тому

It's available now!

Hi, thanks for your patience to teach us. I need to connect 3 serial ports on my esp32. Hw Serial 0 -> fw update and logs Hw Serial 2 -> gps Sw Serial -> gsm I already know that Serial 1 is connected to flash memory. So I need to emulate a serial port through GPIO's. I tried using an Arduino "Serial Software" library, but unfortunately on a compilation error. Reading in some forums and making some changes in the library, I was able to compile the "Sketch"; but the communication of my GSM modem via SoftwareSerial did not work. Note: By connecting the GSM modem separately to a USB / SERIAL converter the communication worked as expected. That is, the problem really is in SoftwareSerial emulation. Could you help?

I am interested in 8266. Would you please, do some videos on interfacing CCTV cams with 8266, so it can stream videos. One more project would be play from 8266 12E, internal 4M memory mp3 or wav files without using external active components. (No TF cards, and serial players) Any help would be welcome..

@ThomasHaberkorn 6 років тому

Hi! Great work! May I ask a question though: Could you provide the Source for the Android app? Would be nice to learn from it.

@LiveSparks 6 років тому

+ThomasHaberkorn I made the app using MIT app inventor and the project file is available at the github page linked in the description.

@olaniyioluseun8250 5 років тому

Hi, thanks for the comprehensive tutorial! Can you kindly help with a python code that functions the way your app functions, i.e., that can scan for available esp32 advertisements and capture the float at the back of ESP... thanks.

@olaniyioluseun8250 5 років тому

Basically, I'm referring to the code in the apk application that does the scanning and utilise the temperature value.

@varelasg 5 років тому

hi, thanks for the tutoriial, im using the code with the firebeetle esp32 and a shock sensor. I send ESP10 if idle or ESP20 if sensor is activating. Your app i receiving values for about 3 secs and then nothing. If i close the app and start the app again, i get again values only for the first 2-3 secs.

I would not recommend following this tutorial anymore. Better methods are out now.

i cant find the .aia file can anyone send me thanks

@pintaric007 5 років тому

Hi, when I use your .apk file app works fine, but when I use your .aia in Mit App Inventor, on app show just -1000, no temperature. Any idea?

@LiveSparks 5 років тому

It won't show any real values on the app inventor itself but it will work if you compile the app or use use tye AI2 companion for testing.

@pintaric007 5 років тому

It works. Thanks.

Arduino BLE library is now available either from Sketch Manager in the IDE, or from here www.arduinolibraries.info/libraries/esp32-ble-arduino I would very much like to see how you might use the library to redo your video example!

@browaruspierogus2182 5 років тому

I don't want to use Arduino but maybe -non OS SDK. Do you know how?

@LiveSparks 5 років тому

You can use ESP-IDF

@s.husain6125 4 роки тому

Can we send Lora packet data to android app using BLE sir

@LiveSparks 4 роки тому

Yes. Watch my latest video to see how to send any type of data with BLE

@s.husain6125 4 роки тому

@@LiveSparks thanks you sir but how to send different sensor value packet data to app using BLE because packet is increpted string and we can not convert to float value to send each sensor value means how to separate sensor value and send to app sir..... If possible please make tutorial on that there is no tutorials available till now

@mhikosale7233 5 років тому

hello which file should i use to install the app in my phone?

@mhikosale7233 5 років тому

and how should i install it, im sorry im kinda new in this things i couldn't find your app in the app store

@LiveSparks 5 років тому

Go to the github link in the description. The app is there with all the other files.

@mhikosale7233 5 років тому

@@LiveSparks i installed it already but. whenever i start scanning it always says ESP device not available i copied the same code you provided but it has the same outcome. ive been stuck with it for days lmao anu suggestions?

This tutorial is really outdated. You should look for some newer ones.

In Wifi, this technique is called "beacon stuffing".

@LiveSparks 6 років тому

+roidroid I didn't know that, you learn something new everyday!

@EmreCanOZKOK 6 років тому

you are using generic libraries.my 12 years old brother making this. but im looking for how can i do this with custom and how i set uuid or anything and how to communicate with phone.how bluetooth is working ?. this video not contain this but the title is "ESP32 Bluetooth(BLE) Temperature Sensor" oh god. this is not ble project.your project is "BHE" Lol

@LiveSparks 6 років тому

At the time I made this video,official libraries hadn't been released. This was just a workaround. There are now better libraries available for you to use.

@EmreCanOZKOK 6 років тому

yes first of all ,thanx for answer.you are right but the title is like a click bait.you can use "basic" because we are developing commercial product and researching something for development .%90 of contents on the internet useless or totally same .we are looking for bottom layer of this operations.I apologize if I said something bad.sorry for my bad english.this is only hobby level.commercial level and hobby level very different i seen this 4 year ago.I have a word "if you really want to make money you should write better code then community."

@kamleshkushwah4079 6 років тому

He is allays change the Bluetooth name and append temperature with Bluetooth name. This is not the right way to communication with Bluetooth....No paring no password only ble.Begin() in loop. (FAKE) WTF

@LiveSparks 6 років тому

+Kamlesh Kushwah This method of communication is called beacon stuffing. And while it is not optimal for this application, it was the best I could do at the time of this video due to a lack of libraries.

@sonukushwah221 6 років тому

It's not working any one try, or it's fake?

@LiveSparks 6 років тому

+sonu kushwh It works for me. What problems are you facing?

@sonukushwah221 6 років тому

it's always show pairing and never ask for a pin and unable to pair. Please make a video for simply connect with the ESP and send serial data, Thanks!

@LiveSparks 6 років тому

+sonu kushwh It's not possible with yhe current arduino libraries.

@sonukushwah221 6 років тому

How did you do it?
