This article is a continuation of the research conducted in [Abotaleb 2023] to analyse the importance of coexistence between different wireless technologies in the instrumentation field. The WebSerial based laboratory stand described in [Abotaleb 2023] showed a limited range of WiFi communication due to decreased Received Signal Strength Indicator (RSSI) levels at points not located at a straight Line of Sight (LOS) from the host controller. The ESP32 controller is the backbone of such a stand, administrating both serial and Wi-Fi communication to send the collected data from multiple sensors to the host controller. In order to increase the range of wireless communication, the WiFi based ESP-NOW protocol will be presented as an alternative to performing such a task from the perspective of possible future application in maritime engineering.
