ESP-NOW peer private data
Posted: Tue Sep 24, 2019 10:44 pm
I'm trying to understand the purpose of the .priv member of the esp_now_peer_info struct.
I'd like to store some data for each paired peer, e.g. number of send errors, so that I can un-peer unresponsive devices after a set number of errors. Otherwise, I'll need to maintain a separate, parallel list of peers. I'll do this based on the results from the send_data callback.
Can I use this ? e.g. by allocating some memory and attaching it to this pointer ?
Or is it truly private and just for ESP-NOW internal purposes ?
I did try this method and just got crashes when I tried to access my data through the pointer.
Thanks
