You just have to combine receiving and sending, like in this simple example based on example_spp_acceptor_demo.c


I have a few questions on this. Where can I find this `example_spp_acceptor_demo.c` file.
The other question is if I pasted the code you have given to the `main.c` file of `BT_SPP ...

it's the 'main' task stack that is the problem. You can adjust the stack it gets in menuconfig.

Where can I find the menuconfig in my project. There doesn't seem to be any menuconfig file in the project. And how can I adjust the stack it gets. Can you please explain that as well. Thank you.

I am trying to send data through espnow. This is my code

/* ESPNOW Example

I reworked on the main.cpp. I have attached the modified file below. But it still gives the same error of ,

"espnow_example: Send error".

Any other tip? Much appreciated.

ESP_LOGI(TAG, "MAC : %d", esp_now_send(send_param->dest_mac, send_param->buffer, send_param->len));


This just prints, I (5887) espnow_example: MAC : 12396. So I'm assuming there is an error whencalling esp_now-send because ideally this should return 0
Likely culprit here

Not without seeing a. the error code, and b, the rest of the code.

I have attached the whole code and also updated my question with the error. Please take a look. Thanks

I have compiled and run the example code which written in C and it works perfectly. But now I want to integrate that example(Written in C) to my main code which is in C++. I made couple of changes where I replaced malloc keyword with new keyword and I compiled it. It compiles successfully but when ...

Hi,

My requirement is for all the nodes able to send and receive. All the nodes should be equal. Not one node a serer and the other a client. How to accomplish this?

Using on/off example won't solve that according to my knowledge. Correct me if I'm wrong

Thanks

So when I create a group what model should I use in each node? . Do you actually need a model for this ?

Is there any example I can follow?

Thanks a lot!!
