When using ESPNow communication between an ESP8266 device and an ESP32, the distance between the devices can indeed impact reliability. If one device is significantly farther away from the ESP32 than the others, it may experience more communication errors or interference, leading to a failure in receiving the "Ack" message.
If the sender did not receive the "Ack", it could be due to various factors. The message might have been lost or corrupted during transmission, or the "Ack" message itself might have encountered issues during its journey back to the sender.
Similarly, if the receiver did not send an "Ack", it could be because it did not receive the message correctly or the "Ack" message encountered problems during its return to the sender.
To enhance message delivery reliability, you can consider using alternative communication protocols like MQTT or TCP/IP. These protocols are designed to provide more robust and dependable message transmission, offering features such as guaranteed delivery and error detection. Implementing such protocols could potentially improve the overall reliability of your communication system.
It's worth noting that the specific implementation and environment may introduce additional factors that influence communication reliability. It's recommended to thoroughly test and evaluate your setup to identify any potential issues and ensure optimal performance.
