Encrypted ESP01 ESP32

[dvpe]

Hi,
I have an installation working very good but now I would like "to play" with security.
I have multiple master sending information to one slave.
My masters are ESP01 and my slave is ESP32.
I am having problem when try to use key to encrypt the message.
The main part of the code:

Code: Select all

esp_now_add_peer(mac,role,channel,key,size)

--> when KEY is NULL, everything is OK. when KEY has value, the receiver (esp32) doesn't receive anything.
is it possible? Does somebody proof this feature?
Thanks in advance.
