Thank you for helping.
Your suggestion did avoid the error, but I still have no succes in
getting data back from the owserver.
I have tried several permutations of message types (4, 7, 8) and format
flags (ownet_flag, persistence) but I only get tcp-frames without data
content back from the server.
My dataframe from client is now like:
0030 fa f0 e0 3b 00 00) [00 00 00 00 00 00 00 01 00 00 ...;.... ........
0040 00 04 00 00 01 04 00 00 00 00 00 00 00 00 2f] ........ ....../
and the info fram Wireshark looks like:
time
0.000000 52838 > owserver [SYN]
0.000486 owserver > 52838 [SYN, ACK]
0.000574 52838 > owserver [ACK]
2.607654 52838 > owserver [PSH, ACK] contains the dataframe above
2.608142 owserver > 52838 [ACK]
2.608504 owserver > 52838 [FIN, ACK]
2.608542 52838 > owserver [ACK]
when I stop the testapplication I get further:
22.598495 52838 > owserver [FIN, ACK]
22.599094 owserver > 52838 [ACK]
I do not understand why owserver sendt the [FIN, ACK] at time 2.607654
instead of a dataframe with [PSH, ACK]
I assume that version=0000 and offset=0000 is correct, but I am
uncertain about sg flags. It says in the docs:
"0x00000100 Ownet request (included for all ownet messages)",
does that mean both from client and from server, and are any of the
flags mandatory?
I can still read the temps locally:
pi@raspberrypi ~ $ sudo /opt/owfs/bin/owread
/28.991049010000/temperature /28.D43C49010000/temperature
12.375 23.75
and as I understand it, owread also get the temps over TCP ?
