Hello :)
I am trying to implement the relay system with USRP2 & RFX 2400. I am using GRC+UHD. (GNUradio 3.3.0 , UHD_003.20110310224233.4c7cc6b) When UHD is used in some cases, the comments come up as below. (1) Target recv sock buff size: 50000000 bytes Actual recv sock buff size: 131071 bytes (2) Target sample rate: 8.000000 MSps Actual sample rate: 8.333333 MSps (2) may be caused because interpolation or decimation rate must be integer. So if the sample rate that I intended is 8.000000 MSps at TX, the interpolation rate(100M/8M=12.5) is not integer. Thus the actual sample rate is different from the target sample rate. Is my guess right? But I don’t know well about (1). What does that mean? Where is “the recv sock buff”? Finally, I am curious about the UART of USRP2. How does the UART operate in USRP2? Thank you for your valuable time. Regards, Bomi
