Android Question Send HEX byte via bluetooth

[StarinschiAndrei]

Hi all,
Could anybody help me what's wrong in my code ! i try to communicate with a device via Bluetooth based on the following description (attached):

i use as a reference , Erel's Bluetooth app example.

Public Sub SendMessage (msg As String)
    AStream.Write(Array As Byte(0x01, 0x25, 0xF8, 0x45, 0x30, 0x05, 0x30, Asc(0x31), Asc(0x39), Asc(0x37), 0x03 ))
   
End Sub

The usage of Asc here looks wrong. Asc expects a single character and returns its unicode point value (same as ASCII).

Thank you. Could you please tell how should i send the command ?I send the command with the application (under windows) provided by manufacturer. I monitored the port (serial port monitor) and this was the sent command : 01 25 F8 45 30 05 30 31 39 37 03

and this was the sent command : 01 25 F8 45 30 05 30 31 39 37 03

AStream.Write(Array As Byte(0x01, 0x25, 0xF8, 0x45, 0x30, 0x05, 0x30, 0x31, 0x39, 0x37, 0x03 ))

AStream.Write(Array As Byte(0x01, 0x25, 0xF8, 0x45, 0x30, 0x05, 0x30, 0x31, 0x39, 0x37, 0x03 ))

Thank you. It is working . But now i should see why the connection is broken after the command is sent.

Hi,
Is there any function that can convert hex 15e in 30 31 35 3E ?
I tried to use

dim val as string     '15e
Log(bc.HexFromBytes (bc.StringToBytes(val,"UTF8")))

but the result is : 313565
