How to access the LQI from CC2540 Bluetooth Low Energy

Raj Sarkar

Other Parts Discussed in Thread: CC2540, CC2530

I am trying to find a way to understand the Link Quality and read the LQI value on the CC 2540. How do we get access to this so we can use it to refine the algorithm within our application? Any suggestions?

Thanks,

/Ray.

The only link quality indication available in the CC2540 is the RSSI (received signal strength indication). You should find information on how to access that in the BLE stack documentation.

Thanks for the reply. We can read the RSSI fine, but for our application we also wanted to know if we can have an estimate of the LQI value. As I understand, it is not possible to read it directly for the CC2540.

Thanks for your reply and should in future new developments happen on this front please do keep us posted.

Dear Raj,

Have you found a way to get LQI value?

Can we use hal_rf or basic_rf functions to obtain it? (for CC2530)
