You are correct, I did not implement the ACK of the espnow protocol and only worked with broadcast packet. For our application, we needed low latency, so we used broadcast for this purpose of not having an acknowledgement packet.
I guess you could implement this using this code as a simple base.
I found that this library works fine when using broadcast mode, but if I configure the target address as
ESP_mac
, then theesp_now_send
function call returns a non-zero error.From the packet capture results, it seems that Linux-ESPNOW does not have the ACK ESP32 module.
