sending byte in code?

[korenron]

Hello,
I'm working on some BLE code that need to send 01 \ 00 in order to turn on a remote LED.

this is the command I'm using

 await client.write_gatt_char(Led_Char, b'\01') # send new value 

and right now I'm working not smart :

New_Led_Status = input(''' Enter new led status: 3 - Led1 - off 2 - Led1 on 1 - Led on , 0 - led off , ''' ) if New_Led_Status == "1": await client.write_gatt_char(Led_Char, b'\01',) elif New_Led_Status == "0": await client.write_gatt_char(Led_Char, b'\00') elif New_Led_Status == "2": await client.write_gatt_char(Led_Char, b'\02') 

I want to enter the value inside 1 command and not write the same command many times(I'm going to handle more options)
what do I need to change?



and another issue

when I run the code on Windows - it's working,
when I run the code on Linux - it's not sending , I get nothing on the remote device
on linux I have
Python 3.7.3
on windows I have
Python 3.10

can this be reason ? - if so what do I need to change?
*** using the same code , and I don't get any errors

what could be the problem?

Thanks ,

There is an int.to_bytes() method. You could convert your int string to an int, then convert that to bytes.

New_Led_Status = 2 New_Led_Status = int(New_Led_Status).to_bytes(length=1, byteorder='big') print(New_Led_Status)

Output:
b'\x02'
