Unlike other wireless devices, the strength of a Bluetooth signal enables developers to create Bluetooth wireless devices such as speakers, keyboards, and others. It is not easy to estimate the range that Bluetooth technology is likely to cover, although it is developed to cover a wide range between two devices. As the RSSI value significantly differs between chipset manufacturers, MOKOBlue employs an absolute and more consistent measure to determine the strength of a Bluetooth signal. For example, a pretty good value is below -50, a fairly reasonable value is between -70 to -80, while -100 indicates no signal at all. The signal is always better when the RSSI value is closer to zero.

When the RSSI value is higher, the signal becomes more robust. The Bluetooth RSSI values are always on a logarithmic scale, negative, and measured in decibels (dBm). The RSSI measurements for every seen device are provided by a Bluetooth radio anytime the device scans for Bluetooth devices. Its measurement depends on the receiving device.MOKOBlue: Original Bluetooth/BLE IoT & Smart Devices Manufacturer īluetooth RSSI (Received Signal Strength Indicator) is a measure that represents the relative quality level of a Bluetooth signal received on a device. There is a point at which trying to obtain more signal delivers diminishing returns, because the quality of the connection is defined by more values than just RSSI (you will find more information on the other measurements in the Mobile Signal Strength Recommendations page). The closer to 0 dBm, the stronger the signal. However, -70 dBm and higher values usually equate to the modem being in an excellent coverage area. The exact numbers vary between cellular carriers. The higher the number, the better the signal. This value relates to the signal strength of the cellular signal from the tower to the modem. The RSSI is indicated by a negative dBm value. In telecommunications, Received Signal Strength Indicator (RSSI) is a measurement of the power present in a received radio signal.
