Hello, thanks for your reply
My reseller gave me the MCU fw 12.21 that I successfully installed using the serial port
I think you are quoting the DSP firmware, that should be
>> bytearray(b'QVFWb\x99\r')
<< b'(VERFW:00045.07\x05)\r'
I can surely test a new FW but I need a way back in case something goes wrong
Possible ?
I also have a axpert max 7200 that in a seemingly random way switch to bypass and is stuck there unless a full reboot, without a utility connected.
So, I am really curious on what is the "known bug" and the possible "better solution" than mine
Thank for your help
