Bind Limit of 20 (AEGHB-8)

[tiki30]

Hi, can you explain exactly what limits the pairing of devices to a maximum of 20 ?. If I need to communicate with more than 20 devices without using broadcast, is there a mechanism to do this ? Many Thanks.

The WIFI lib and memory cost limit the pairing of devices to a maximum of 20. If I need to communicate with more than 20 devices without using broadcast, is there a mechanism to do this ? ==> You can add peer address before sending and delete peer address after sending.

espnow_add_peer(src_addr, NULL);
espnow_send();
espnow_del_peer(src_addr);

If I broadcast would there be a limit. I can set wifi to 15, however, i am switching to esp_now. I am thinking broadcast is just to one peer FF's in mac. I dont care about the result of the send

You can ignore the limit of 20 in broadcast mode. We have tested 100 devices as responder which have the max delay timer is 315ms.
