Hi again, I found an easy way to reproduce the problem. I use two x310's and run the tx_timed_samples as: tx_timed_samples --args "addr0=192.168.50.2,addr1=192.168.130.2" --secs 0.5 --nsamps 100 sometimes it fails, sometimes it works. I use larger number of samples to be able to notice

Hi folks, I have 2x X310 connected to Octoclock (10 MHz + PPS), each with 2x UBX frontends. I control them from a C/C++ program. Since there are 4 channels, I create 4 tx streamers in order to transmit timed samples on each of them. The transmissions are not at the same time and this is the r

Hi folks, I have a C/C++ code that transmits frames in a given time slots from 2x X310. All 4 AFEs are used (2 on each X310). The duty cycle is relatively low, 1 frame in each 10 ms. Frame duration is a few hundred microseconds. The processing is not CPU intensive. The problem is that all 4 c
