ESP32 Forum

Hello Everyone,
I'm new to mesh and wants to send sensor data from one node to another, for trial i'm using 5 esp32-WROVER-B boards, I'm using internal_communication example for this so using this, connection between the different boards is done but i'm not able to send data from one node to another. Do i have to use ESP-MDF for sending data? Can't i do it with ESP-IDF ? please help...if anyone has a code that would be grateful and sorry for bad english.
thanks

It might be a little easier if you use ESP-MDF.
If you want to send data from one node to another use IDF only.
First, you need to know how to use esp_mesh_send() https://docs.espressif.com/projects/esp ... esh_opt_ti
The mac address of the destination node need to be set to the parameter “to”.

Feel free to ask if you have any more question.
