Is there Bluetooth example for arduino?

[pwreng]

Hi, I have ESP WROOM 32 (support Wifi&BLE). I have been looking for an Arduino example using BLE.
I have one for Eclipse which seems too much complicated for me.

Any help is appreciated.

As far as I know, BT is not implemented in arduino yet

You can use everything available through IDF. I see lots of work still being done on the BT stack and I see no point into investing lots of time into something that is not finalized and instead improve and integrate things that are done.
Surely there will be Arduino "integration" in the means of easier-to-handle classes :)
Imagine what will happen now with issues here if something in BT breaks in a mean time. People will blame Arduino and I'll be chasing my tail :D

p.s. Please try search issue before submitting a duplicate issue. I'm closing this as there are at least 2 others available

Well, it's good that we at least get an update on this, I was wondering about this for 2 months already :)
People ask about it on the forum too and it's a lot of confusion.

and in those 2 months everything about BT in ESP32 changed :) imagine how that would have worked

Please can someone explain how to implement IDF from the IDE? It doesn't compile plain example files from the IDF

We now have a sample bluetooth library that works 👍

@birkir Does it support ECDH or any other secure BLE connection?

I tested SimpleBLE and I have error:

What could be?

[me-no-dev]

I do not see an error

[ESAlexhi]

I do not see
Serial.println("Press the button to change the device name");

and
BLE32 at: .... :( in my smartphone (BLE)

ble.begin("ESP32 SimpleBLE"); //crash

[jarda195]

I have the same problem...

[jarda195]

Still waiting on a line

ble.begin("ESP32 SimpleBLE");

[peterrautek]

I see the same behaviour:
ble.begin("ESP32 SimpleBLE"); //crash
