Re: ESPNOW Slower than expected RTT (Round Trip Time)

Ok I was able to get this working You need to include: #include "esp_private/wifi.h" and disable AMPDU TX and RX via menuconfig: DISABLE BOTH Components => Wi-Fi => "WiFi AMPDU TX" & "WiFi AMPDU RX" Only then does it compile and enable the set rates! Successfully got it down to 689Micros!! Current s...

Re: ESPNOW Slower than expected RTT (Round Trip Time)

How did you compile this function? error: implicit declaration of function 'esp_wifi_internal_set_fix_rate' [-Werror=implicit-function-declaration] esp_wifi_internal_set_fix_rate(ESPNOW_WIFI_IF, 1, WIFI_PHY_RATE_MCS7_SGI); This seems to be a set of functions that we can not use? Can you elaborate?

Re: ESPNOW Slower than expected RTT (Round Trip Time)

I believe the default ESP-NOW bit rate is 1 Mbps.
Where is this documented?
We are starting to experiment with increasing the ESP-NOW bit rate
How are you doing that? Can you elaborate?

Re: ESP NOW maximum peers

If you want to do it legitimately, no.
BUT you can kind of get way with it by doing a UNICAST espnow send and setting all your nodes to have the same MAC address.

ESPNOW Slower than expected RTT (Round Trip Time)

I have been testing RTT times on 2 ESP32 modules & have it down to an average of 6000 micro seconds (6 mili seconds). Source for TX: https://github.com/leonyuhanov/ESP32_ESPIDF_ESPNOW/tree/master/espnowv1 Source for RX: https://github.com/leonyuhanov/ESP32_ESPIDF_ESPNOW/tree/master/espnowv2 -The TX ...
