OK, need to call on all of you experts once again.
we are having troubles with one particular batch of Nanos ?not being willing to be uploaded new code.
this batch of three did not seem to have a boot loader on it, so I followed instructions on the Internet and used an Arduino Uno to load a boot loader on to them, following which they initially ?seemed to work. ?However, we have had intermittent problems getting the IDE to load to these Nanos.?
anybody have something we should check? ?we have also made sure that we have the right comport, right type of device, I have suggested to the gentleman having trouble that he check com port speeds at Cetera at Cetera and we are a bit perplexed ??
suggestions? ?You guys have been great, answering lots and lots of issues quickly
?
