BladeRF RX overrun

eduemon · Post by **eduemon** » Wed May 29, 2024 7:17 am

Hi everyone,
I am currently working on a radar development by using 2 bladeRF. I transmitted a signal using the 1st bladeRF and received its echo through the 1st bladeRF and 2nd bladeRF RX ports. I am using GNU radio to design the radar block. To control the 1st bladeRF (for Tx and one Rx) I used the "Osmocom Sink" and "Osmocom Source". To control the 2nd bladeRF, I used the "bladeRF source" block. I could see the signal transmitted and received by the 1st BladeRF. However, I could not any signal received by the 2nd bladeRF. When I check the GNU radio terminal, I saw this log and at the end of it, it says an overrun has occurred on my 2nd bladeRF.

Can someone help me to overcome this problem?
Thank you very much.

P.S. I have made sure that both BladeRF work well by testing them separately.

An overrun in your second bladeRF indicatesgeometry dash that the device is unable to process incoming data fast enough, causing data loss. Here are a few steps you can take to troubleshoot and potentially resolve this issue:

1. Use a high-speed USB 3.0 port.
2. Update firmware and drivers.
3. Lower the sample rate.
4. Increase buffer size in GNU Radio.
5. Run bladeRF devices in separate processes.
6. Increase thread priority in GNU Radio.
7. Monitor system resources.

If none of these steps resolve the issue, providing more detailed logs or specific configurations used in your GNU Radio setup could help in diagnosing the problem further.
