espnow_security examples not working (AEGHB-134)

[horsemann07]

Hello,

I was trying to run the espnow security example, I connected two esp32, one responder and one initiator. On initiator side, I did not receive any responder info. I tried to increase the time of initiator stills result is same. Before I tried esp-now release v 1.0.0 there it was working properly. But in esp-now v2.1.0 I m facing issue.

Env:

• ESP-IDF v4.4 IDF version used
• ESP32
• Linux Env

Did anyone test the security example?

@horsemann07 I run the command idf.py create-project-from-example "espressif/esp-now^2.1.1:security" and test it on both ESP32 use IDF v4.4.4, it works fine:

Hi @lhespress

Thanks for the verifying on your side, Its working now. I have to clone the repository again to work. Not sure why before it was not working,

Thanks for the reply!

[horsemann07]

Now I understand why it not working previously. I made some changes to the espnow code here.

There I remove other in tnings in espnow_frame_format_t stucture and except vendor_specific_content.

I m little confuse on this, espnow_frame_format_t is given as example for user or it used by espnow lower layer, so any modification in that structure leads to problem?

@horsemann07

This project care some filtration information, eg: RSSI. But, it doesn't have API or parameter to get wifi_pkt_rx_ctrl_t from receiving data before ESP-IDF v5.0,

Therefore given espnow_frame_format_t which be match with ESP-NOW Frame Format as an example for user get wifi_pkt_rx_ctrl_t, just as you point, any modification in that structure will lead problem.

The user doesn't care this as esp_now_recv_info_t include it from ESP-IDF v5.0.1.

Thanks @lhespress for clearing my confusion.
