When trying to use “BX31xxBlTest.exe com04 -u BX310x.2.7.3.bin” to update a bx3105 from rev 2.63 to rev 2.73 I get a response
C:\Users\User\BXPROG>BX31xxBlTest.exe com04 -u BX310x.2.7.3.bin
\.\com04
connection failed -103
I have checked and com4 does exist and is connected to the device input.
what does this mean? Do you have more detailed information on the process and possible errors.
I have done this procedure successfuly several times and had no problem in the past.
