Help with SSH connection to a Raspberry Pi using LIBSSH2
Hi! I need help 🙂
I´m working on a slow control system for reading the power supply of some Silicon Photomultipliers through a SSH protocol from a Raspberry Pi, using LIBSSH2 toolkit.
I´m getting two main errors, up to this point.
- Error 5300: SSH write timeout. That I get when after the program gets stuck in the write all.vi
- Error -8100: [Execute Again Error] The operation has been marked for non-blocking I/O but
the call would block.- This error gets solve when I increase the value of the timeout, but after one interation in the loop it re-apears. If I stop the program and without waiting for a moment I run it agian it also apears. But if I wait a minute before running it again the error is gone, util the first iteration.
If anyone has any ideas on how to solve it I would really appriciate it ❤️

hi! can you trigger this kind of behavior any time, you run your code, or does it occur sporadically?
so, do you run every time into that time-out you execute your .vi?
as changing the time-out time does resolve this temporarily, the workaround is to execute the .vi once and wait long enough before starting another execution.
some wild guess
try to keep the reference (this is an asumption) in the shift register of another while loop around the one existing while loop
