Hi,
i tried your patch on winxp just with udpsend and had the same problems: error: udpsend_send: item 0 (-1.000000) is not between 0 and 255 error: udpsend_send: item 0 (1.100000) is not an integer so maybe the problem is not OSC but UDP? as it seems to handle only single bytes. So my question how to send a -1.1 over UDP? g.
haven't looked at the patch, but there are two possible reasons for this:
- somebody (the patch?) is injecting non-byte-values into the data to
udpsend. udpsend takes a list of bytes, not a Pd message. this means: you cannot just send the message "/test -1" to udpsend, you need an object inbetween that translates the message "/test -1" into a binary format. [packOSC] is one such object which will translate the given message into a list of bytes "47 116 101 115 116 0 0 0 44 105 0 0 255 255 255 255" (all atoms are floats and the values are integer and between [0, 255]). [udpsend] is NOT a drop-in replacement for [netsend 1]!
- very old(!) versions of [udpsend] (or was it [udpreceive]?) had a
problem with signed/unsignedness, resulting in "255" (binary 11111111 in unsigned) being interpreted as "-1" (binary 11111111 in signed). if this is the case, you have to upgrade udpsend/receive (e.g. install a newer stable release of Pd-extended)
