The esspresif documentation for esp-now (MicroPython) states:
The maximum number of paired devices is 20, and the paired encryption devices are no more than 16, the default is 6. If you want to change the number of paired encryption devices, set CONFIG_ESP_WIFI_ESPNOW_MAX_ENCRYPT_NUM in WiFi component configuration menu.
However, it also states that:
ESP-NOW is a kind of connectionless Wi-Fi communication protocol
So my question is, how is there a device connection limit of 20, if it is "connectionless". If I were to turn on 30 ESP8266 Modules, can i not broadcast to all of them, from 1? Or is this limit referring to the amount of peers you can have "listed?" and therefore, can transmit to simultaneously.
