Temperature monitoring is considered one of the significant vital signs in clinical practice for detecting malignant hyperthermia, and overheating. For collecting and transferring body temperature measurements to a host computer for further monitoring over time, Internet-of-Things (IoT) system become essential. Several wireless communication protocols are now used to create wireless body area networks, which require different types of wireless transceiver modules. Nordic's nRF24L01 is one of the most remarkable wireless transceiver modules that can be employed for vital signs monitoring owing to its low power consumption, low price, and acceptable data rate. However, some important communication features are missing from the nRF24L01 module which are essential to increase the reliability and stability of the communication system for monitoring. In this paper, an extra communication layer is proposed to improve the communication scheme of nRF24L01. To test the proposed communication protocol, two devices were designed, namely the master device and the wireless sensor node with a temperature sensor. The experimental results' findings established that the connection status is probably tracked by both the slave node and the master device. Additionally, the error between the transmitted temperature reading and the received temperature readings is zero. The lowest recorded temperature reading was approximately 36.5 degrees Celsius while the highest recorded temperature reading was about 38.6 degrees Celsius for a volunteer patient.
