Hi, thanks you for your reply. Tx side it's all ok. The problem is on Rx side, Using Oscilloscope with usrp_fft.py or saving samples on disk i noticed all packet are transmitted. This is true using high value of interpolation/decimation factor (very low bit rate). What do you think about this

Hi, I've observed that all URB allocated in the Tx side are correctly proccesed. For example: Data -> 25 Byte (from a mpg file) Total payload -> 80 Byte (Data + CRC + Padding + Header + ) Total Byte to transfer with a BPSK modulator -> 80 * 8 (bit of a char) * 6 (sample per symbol) * 4 (Byte -

Hi at all, i've a question. I send a packet data with a variable length to USRP via USB every 1 second. At the receiver side, using usrp_fft.py, i notice that the most part of packets aren't transmitted. Someone could help me? Thanks Giuseppe PIlla ___
