hi again
I jad a look at the available logfile:
Apparently everything goes right upto the point where we send a
de20/cmd_scan_param. The 4 bytes ack (confirming a packet of 0x40 bytes)
on the command is received back(T=6.240).
We then expect to start read an 8 byte response from the scanner, so we
send a BJNP read request to the scanner and wait for a response, but
nothing arrives, not even a data header.
Sp it would indeed be good to see a wireshark trace of the TCP/IP data
flow as well as a trace. Nicolas, would it normally be possible that a
response to de20 could take more than 20 seconds? I seem to recall that
timeouts in the past were in the order of seconds and less than 10
seconds,so I would guess that 20 seconds is way too long, right?
kind regards, Louis
