Hang on I have a mighty headache this morning so need things dumned down.
Please explore how you have installed the software, connected hardware and tried to access the devices in M5Burner and are you sure you are accessing the correct com port?
@pandian-nano Thank you. I have read through that several times and it makes no more sense than the time before. I'll eventually come across something that I understand and it will sink in. Thanks again.
