the manufacturer has given communication protocol for various operations.
The manufacturer has not provided any drivers for the device will that cause a problem in communication.
Thank You

Hi naman,
when the manual states "send byte 0x15" you need to send exactly that byte. Right now it seems you send 4 bytes "0", "x", "1", and "5" which is wrong!
Set your string constants to "hex display" mode and input the needed byte values then!
Setting a timeout of 1000s (or >16min) is also not recommended…

I'm going to add that the "0x" isn't part of the code you should send. That's just telling you that the following number is a hex number.
