My colleague Simon has already suggested you to try an unofficial Android app that was used by one of my ex-colleague.

Can you please suggest me any app which is compatible with nRF5340 for throughput test using a mobile phone or a PC.

If you do not want to use phone app or other peer program then you cannot test BLE throughput in a loopback way.

But i have only nRF5340 DUT.

However, what you can do is indeed use a PC or phone as one end of the throughput test. We don't have an application doing this, but it should be possible to implement. Note that you will be bottlenecked if the peer does not support the 2Mbps PHY and MTU throughput required for throughput testing.

Syed,

No you cannot do a throughput test on a single DUT. Loopback does not work here unlike doing a loopback on Serial peripherals. On serial devices, you have different pins for RX and TX but our products have only one radio that can be either in TX or RX mode at a time. So there is no way we can time that loopback to send and receive the data.
