ESP32 Bluetooth is working. How to use Interrupt?

[stefan.erni]

Hi Ben

Yes thats a good idea . If I dont need bluetooth date I ignore it.
A command for the interrupt is needless.


Now the SPP is working much better but...
There is still a lot of data if I connect or disconnect the port from the terminalprogram in my computer.
To check if the Bt is connected I use the command "CheckConnectionStatus"

So can You remove this data also?

Hello,

Hmm it looks like those warnings are deeper in the ESP32 compiler itself. I think you can probably turn those off to by editing this line in the config file.

CONFIG_BT_LOG_RFCOMM_TRACE_LEVEL_WARNING=y

hopefully just change the y to n and that should do it. There are a lot of other similar settings in the same block in the config file so you might want to switch off others too.

Hi Ben

I can set it to

# CONFIG_BT_LOG_RFCOMM_TRACE_LEVEL_WARNING is not set

but after compile to target it's set again to

CONFIG_BT_LOG_RFCOMM_TRACE_LEVEL_WARNING=y

Checking if Python packages are up to date...
Python requirements from C:\Users\Kfs-Forschung\Desktop\esp-idf\requirements.txt are satisfied.

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

idf.py build

Hi Ben

I used the "idf.py menuconfig" what I found in a post
There is a way to set BT Log off

Now I dont have a additional signal in the SPP.

I can connected to esp32 bluetooth and sent data from esp32 to android (serial bluetooth terminal ). But how to send data from android to esp32 connected to laptop and show the data on serial monitor
