I try to transmit ASCII: NUL dec: 0

If I set CV98=1 and transmit 1Serial("{\0%c[98CV]\255}")
I get in HEX: 00 01 FF it is correct.

If I set CV98=0 and transmit 1Serial("{\0%c[98CV]\255}")
I get in HEX: 00 FF it is incorrect.
I need in HEX: 00 00 FF
I must be flexible with a variable CV and can not hardcoding \0 in the real command (measuring value)

What do i wrong?
Thanks

Hi Volker,

Unfortunately, you cannot pass the integer value and convert it using %c since the conversion will take ASCII representation and the representation of ASCII 0 is NULL (empty).
