Hallo,
How can i send chr (0) via udpwrite.
I have try
udpwrite "192.168.1.97" , 8899 , chr(66) & CHR(0) & chr(85)
But only the first byte (66) is received.

Maybe this will help?

Thank you for you the link.

But this is not a solution.
i must send the a sequence with end chr(0) & chr(55).

it is possible to send binary data?

have a look at ESP8266 Send / Receive Binary Data using UDP
