In the end it doesn't really matter which ESP32 you are using as long as you change the "board" choice in the Arduino IDE to the correct board.

thanks, will help in my project. great video!

@asali-channel 5 років тому

You're welcome, goodluck with your project and thanks! :)

putting this behind a paywall is hella sus dude. FYI he didnt show the bottom where you need to start "BLEAdvertising"

@WistrelChianti 4 роки тому

Is it me... or do you overwrite your TX characteristic with your RX characteristic...? (it might be me)

@jurgenkriebs9405 5 років тому

It is so good to folow you and your style is very engaging and also very well made maby your intro is a bit to long but other than that it is very very well made

@asali-channel 5 років тому

Thanks for your comment! I've been working on the intro too, don't know what to do with it yet but I'll probably change it in the future!

@jurgenkriebs9405 5 років тому

I have a further question if it is possible to use the data that was received outside that loop you created to deal with the date?

@asali-channel 5 років тому

@@jurgenkriebs9405 I am not sure if this is possible, I think you will have to try this out for yourself, HOWEVER if you were to create an application in let's say C# you could send in data AND a date aswell, it would be like adding "12-12-2019" to the same string and you could catch this in Arduino and split these values up and do something with it. Also if you are interested, I will be uploading a new video by Friday where I will be covering DEEP SLEEP which could be very interesting if you are planning on running your ESP32 on a battery! Deep sleep will enable your ESP32 to consume less battery when it's not reading out data from your heart rate sensor. In my case it lowered the mAh from 40 to 1 which is a huge difference.

Thanks this is just the video I was looking for but I have run into the error "'class BLEService' has no member named 'createService'"

@shanehayden7765 2 роки тому

how do you define the service and characteristics of the phone ?

@rickbran7541 3 роки тому

I recently buy new esp32 via online shop, but my phone does not detect its bluetooth but wifi connectivity is ok i keep pressing "en" button but i still nothing...how can i enable its bluetooth capability?

@purplegirl6103 2 роки тому

Hi, I have a color sensor with DEC value …how to send it

@remnrom15 Рік тому

How to receive multiple data and separate them

@0805bryan 5 років тому

I want use esp32 to send data but How to send more than 20 bytes in each connection

@asali-channel 5 років тому

If you want to send out more data or in a more continuous stream then you should look into normal Bluetooth connection, I presume BLE uses a different method for this.

@shashih9130 4 роки тому

can we send whole txt file via bluetooth in esp 32?

@asali-channel 4 роки тому

Yes but probably not as a txt file, if you can't find a way to send the txt file then try to convert your contents of the txt file to a string and send this? Also check if there is a limit of data that can be send over bluetooth in one go, not sure if there is a limit tho
