WANT TO FIND LQI (Link Quality Indicator)

Thank you Jared,

Now i understand that for LQI i have to use IEEE 802.15.4 protocol in nrf52832. There is EDSAMPLE register to get LQI and it only accessible in IEEE 802.15.4 protocol. I think in BLE protocol in nrf52832 I can't get LQI.

Hi,

Getting the LQI from the Radio while using the Softdevice is not possible as it's not part of the Softdevice API. The Softdevice doesn't allow the application to access the Radio or its resources unless you're using radio timeslots.

You can find the sourcecode of the OpenThread here.

In this diagram, there is LQI bit but there's no register for getting it. so how the Zigbee/Thread get the LQI?

no the Softdevice API doesn't expose this feature.

Hi Jared,

Thank you for your effort. I know the LQI is not for distance measurement but i can use it for error correction in distance measurement with RSSI. I am using softdevice s132 and sdk15.2 . Is there any way to get the LQI in ble ?

Hi,

I read the nordic infocenter documentation about LQI in 2.4GHz Radio module but don't get a way to access it.

Unfortunately, The Link quality indicator is only relevant for Zigbee/Thread and not for BLE.
