Although Retevis RT24 seems to be supported by CHIRP I cannot connect to it. I get the message "Radio refused to enter programming mode 2". I am using software version " chirp-daily-20200807". If I use the original Retevis software I can read and write the device without a problem so I guess it should not be an issue with the USB-Serial driver.

Does anybody have an idea what I do wrong here?

Thanks,

Michael
