GSE board does not receive commands under specific conditions #154

Open jtalier opened 2 years ago

jtalier commented 2 years ago

I would like to test this on other boards. Essentially the GSE board was shown not to receive the first two commands (was using valve commands) after either:

  1. The Rs422 converter was connected for the first time. If it was connected before and sent commands (and not disconnected) this does not occur
  2. The Rs422 converter was unplugged/ lost connection during a test. Then the next two commands will not go through

After these two commands do not go through the other commands go through just fine. This bug was found to be present in older versions as well.

If this is not firmware related, then could be that when the port is opened for the first time it needs to be flushed somehow? Needs more testing
