Weird, are you sure the client is sending this properly? Anyway we do
store the data in a buffer even if was sent together with put cmd, Im
very suspicious that this is not the problem since we would have
notice this before. Btw obexd does not push/send files obex-client
does, are you talking about obex-client?
