Tool/software:

Hi, TI support

Can you tell me about understanding of Bluetooth RSSI?

how to judge that signal is OK, good.

What does it mean 0 to -70 dBm meaning signal OK?

I need to understand in detail.

And I need detail relate my project in use.

I use project Simple Central Copyright (c) 2013-2019, Texas Instruments Incorporated

simplelink_cc2640r2_sdk_3_30_00_20

Function "SimpleCentral_getConnAddrStr(connHandle), rssi)"

Thank,

Vasu Khwanyuen

    Hello,

    Thank you for reaching out! 

    RSSI (Received Signal Strength Indicator) is a measurement of the power level that a wireless device receives from a signal, such as Wi-Fi or Bluetooth. It is typically expressed in decibels (dBm) and helps determine how strong or weak a signal is at the receiver’s end. Higher (less negative) RSSI values indicate stronger signals, while lower (more negative) values indicate weaker signals. RSSI is commonly used to assess connection quality, estimate distance, and make decisions about network connectivity in wireless communication systems. RSSI is also dependent on the Tx power of the device, which will directly correlate with the RSSI value.

    There are a lot of great resources online that also provide an in depth explanation on RSSI.

    I hope this helps!

    Best Regards,

    Tarek
