Regarding my post below, I have traced back the error and came to a result
that the error is occurring in device.cpp file. This line in the catch block
throws an error:
device::sptr dev = maker(dev_addr);
I beleive there is something wrong in : Arg: addr=192.168.10.11
192.168.20.11 192.168.30.11 192.168.40.11, recv_buff_size=50e6 50e6 50e6
50e6
Does the block support multiple buffer resizing? or maybe I'm not
addressing the devices properly.
Looking foward to your reply.
