Host mode:
1. Confirm that both the PC and E312 have been updated to UHD v4.0. See this
link for the update method.
2. Connect the PC and E312 to the same network through a router. The E312 uses DHCP by default and can automatically obtain an IP address.
3. Run the
uhd_find_devices command to confirm that the UHD driver correctly finds E312.
4. Open
GNU Radio and open the designed grc project.
5. Run the grc program to confirm that the host mode can operate normally, and note that the sampling rate can only reach a few MHz.
Stand-alone mode:
1. Modify the parameter
Generate Options in the Options module to No GUI , as shown in Figure 1. And delete or disable the GUI-related modules in the corresponding grc design.
Figure 1
2. Click
Generate the flow graph to generate a Python script file.
3. Transfer the generated Python script to E320.
4. Run the script, and the error shown in Figure 2 appears. This error will occur when the Python script is run on the E320 for the first time. Just run the script again, and the error will not be triggered later, as shown in Figure 3.
