Check Radio Firmware

The UHD™ firmware on the USRP™ radio hardware must match the UHD firmware on the host computer. You can find the latest supported UHD firmware version in the current Release Notes. To download the UHD firmware for Ethernet-based USRP N3xx radios, see Configure Host Computer for Ethernet-Based USRP N3xx Radio Connection. Alternatively you can download the UHD firmware from https://files.ettus.com/binaries/cache/n3xx/meta-ettus-v3.15.0.0/.

To check the UHD firmware version loaded on your radio, use the getSDRuDriverVersion function.

If your radio requires a UHD firmware upgrade, see USRP Radio Firmware Update.
