From the detectionconditions, the RSSI value in the environment has a wider detection range,which is more suitable for users to use RSSI.

When the wireless module is inthe receiving state, the intensity of the radio frequency signal in the samefrequency band in the current environment can be detected.įor the receiving packet RSSI, the RSII value can be generatedonly after the module receives the data normally and the RSSI value in theenvironment can detect the signal strength in the current environment at anytime as long as the module is in the receiving state. The RSSI valuein the environment is also the frequency noise. The receivingpacket RSSI is the register value of the signal strength of the currentlyreceived data after the wireless module of the receiving segment receives thedata, that is, the receiving module obtains the signal strength currently sentby the transmitting module. Many wireless chips have two RSSIs,one is the receive packet RSSI and the other is the RSSI in the environment. Display of RSSI of wireless productsįor the displayof the RSSI signal strength, the modules of different wireless chip solutionsexhibit different values, and in general, there are multiple RSSI distinctionsfor different wireless chip manufacturers. Thesignal-to-noise ratio (SNR) is also calculated by RSSI, SNR = Signal/NoiseRatio, which is the power ratio of signal to noise. The unit is the unitof power, which is generally expressed in dBm.

It is related to the transmit power of the wireless module, thedesign of the RF front end, and the gain of the antenna. Refers to the signal strength when receivingwirelessly. RSSI isgenerally used to describe the strength of wireless signals, that is, Receivedsignal strength indication.
