Nuand BladeRF x40/x115 Packet mode

[marjoriecarp]

Hello,
Has anyone successfully managed to send PDUs to and from the host computer to a BladeRF x40/x115? I have a few questions as I cannot get the FPGA to act on those packets. i.e. set LED2 high if the second byte is 0xFF for instance.

I know it is supported, and the libbladeRF does not return an error, but I must do something wrong on the FPGA side.

Any advice?

I would recommend checking the FPGA code to ensure that it is correctly configured to interpret the incoming packets and respond accordingly. You may want to verify that the FPGA is properly configured to check the second byte of the packet and set LED2 high if it matches the desired value of 0xFF. Double-checking the logic and debugging the FPGA code could help identify any potential issues.

Hey! I haven't worked with BladeRF specifically, but I've definitely been down the rabbit hole of getting hardware to respond to packets. Frustrating stuff! Have you double-checked your byte alignment in the FPGA code? Sometimes a simple off-by-one error can cause headaches. It reminds me of playing Eggy Car - one wrong tap and everything goes tumbling down! Maybe try simplifying your FPGA logic to just the LED control, see if that works, then slowly add complexity back in. Good luck debugging!
