How to receive data from the buffer | Arduino Compatible Compiler for LabVIEW Discussions | Forum

Hi, I have a question, I am trying to read data from a buffer (12 bytes), first I send a command in hex and I expect the answer in hex too, but I dont receive anything, I am using the "serial check for bytes" and write again to see what I receive but anything apears there, on the other hand if I remove the "serial check for bytes" and put in the "serial read for write" a 12 for the 12 bytes it works but seens to be than there are more than 12 bytes acording with my code, how can I get this data correctly?

Thansk.
