Using BT and WiFi with ESP32S3

Hi everyone,

I would like to use BT to get data from nRF52840 microcontroller and then send this data to a server by using WiFi connection.
My question is, would BT and WiFi interfere each other in ESP32S3 since they use same antenna.

Thanks in advance.

Hi there,
You can with certain caveats , Here is an Example that works.

Using both Bluetooth (BT) and WiFi on the same device, such as the ESP32S3, can potentially lead to interference since they share the same antenna. Both Bluetooth and WiFi operate in the 2.4 GHz frequency band, and their signals can interfere with each other. by using this i don’t face any problem even i playing free fire hack mod apk

Hi PJ,

You answer my all questions :smiley: . Thank you very much. I checked it little bit but it looks complicated… Since I dont have much time I might jsut use RX TX pins for this project.

Have a nice day.

Hi chrisown,

Yepp, that is what I mentioned as well. But there is something called time slice for WiFi and BT. Here you can read.

Thanks for your response. Have a great day.

You can use BT and WiFi with ESP32S3. You have to check these documents:

If you are considering making a Human presence radar using ESP32S3, you can check this tutorial:

Hi liaifat,

Thanks for your response. I will check them. But aren’t they little bit complicated, I am a beginner :frowning:.

Have a great day.

Yes, no doubt that the process is tricky.

Hi there,
Well almost,
Ideally you use separate cores, that alleviates any problems with time slot interference.
