ESP32 Bluetooth update please?

[MJU20]

I've been watching the discussion about the ESP32 bluetooth component (like: viewtopic.php?p=17368&hilit=bluetooth#p17368 and viewtopic.php?p=4466#p4466 ) and so on.

But what is the latest news on this component?

I have found this dir: C:\Espressif\frameworks\esp-idf-v5.3\mtxesp32s_sdkconfig and know from the past how to edit the menuconfig.bat
But what do I need to edit to get the Bluetooth on my ESP32_Wroom32 working?

I'm using the ESP32 bluetooth example from the Wikipage: https://www.flowcode.co.uk/wiki/index.p ... (Wireless) but this doesn't show the device on my computer or smartphone.

All I want to do right now is to connect a ESP32_Wroom32 with my smartphone and use a serial terminal to send data to the ESP32 and show this on the COM port.

In my idea the ESP should be visible as a device on my smartphone, I could connect to it (without access codes or so on) and use the terminal to send data?

Could someone please guide me through the steps that I need??

Hi MJU20

That should work with the smartphone.

You have to start the menuconfig.bat
Can You try to start this?

Hello Stefan.erni,

I know how to edit the menuconfig.bat, but what settings do I need to edit?
There are many settings for the Bluetooth but I can't see which I need to edit..

Thanks anyway

stefan.erni my hero!

You can't imagine how long I was looking to get this feature working.
Thanks!

I hope this can be something other users can use too.
Maybe something that can be put on the Wikipage??

I will post my config too because I have another version of the IDF this could be of some use to other users.
