Hello.
Using owfs-3.1p4.
I need to write binary data to an external sensor.
I do this settings:
owfs.conf
...
SCRIPT: "RELAY_SET", "constant_family", b1024, 1, u, /opt/_read,
/opt/_write, ''
...
The main is b1024. Is it right?
And write from a client by perl script:
OWNet::write( "$dev_ip:4304" , "/relay_setting/RELAY_SET", `echo -n $ss
| gzip -c` );
As you see, I write a gziped data.
Client Hexdump is -
[0000] 1F 8B 08 00 6C 3D 01 58 00 03 33 D4 F1 F3 D7 31....
But!
root@CONSTANT:~> owread -s 172.19.19.10 /relay_setting/RELAY_SET | hexdump
0000000 088b 6c00 013d 0058 3303 f1d4 d7f3 d031
0000010 77f1 0373 0692 3a3a 46ca 02e8 e8c6 2602
0000020 02e8 e8a6 6602 02e8 e8e6 1602 02e8 be00
0000030 9c53 88e3 0000 0000 0000 0000 0000 0000
0000040 0000 0000 0000 0000 0000 0000 0000 0000

My script make a simple cat to file. We are can see this file:
cat constant_control.bin | hexdump
0000000 088b 6c00 013d 0058 3303 f1d4 d7f3 d031
0000010 77f1 0373 0692 3a3a 46ca 02e8 e8c6 2602
0000020 02e8 e8a6 6602 02e8 e8e6 1602 02e8 be00
0000030 9c53 88e3 0000 0000
0000038
I think, first byte is lost and...
By another words, I can unzip the owread data.
Please, where is first byte or my mistake?
cat /opt/_write
#!/bin/sh
RW=$4
case "$RW" in
read) cat /etc/constant_control.bin ;;
write) cat > /etc/constant_control.bin ;;
esac
Thanks.
