Tony

• The firmware seems to work, will do more validation with TTL Cable (Cable with Anni)

• Still need to do actual test with CV people

• Loopback test

  • interrupt / detecting start of message work?

  • in order to receive rest of message polls? impossible to do loopback with poll…can only do one thing at a time? Can’t send and receive.
