padd(bytelist, length, padding=`'FF'`)

source code

Padds a byte list with a constant byte value (default is x0FF)
bytelist: the byte list to padd
length:   the total length of the resulting byte list;
          no padding if length is smaller than the byte list length
padding:  padding value (default is 0xff)

returns the padded bytelist
example:
padd(toBytes("3B 65 00 00 9C 11 01 01 03"), 16) returns [0x3B, 0x65, 0, 0, 0x9C, 0x11, 1, 1, 3, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF]
padd(toBytes("3B 65 00 00 9C 11 01 01 03"), 8) returns [0x3B, 0x65, 0, 0, 0x9C, 0x11, 1, 1, 3 ]

toASCIIBytes(stringtoconvert)

source code

Returns a list of ASCII bytes from a string.

stringtoconvert: the string to convert into a byte list

returns a byte list of the ASCII codes of the string characters

toASCIIBytes() is the reverse of toASCIIString()

example: toASCIIBytes("Number 101") returns[ 0x4E, 0x75, 0x6D, 0x62, 0x65, 0x72, 0x20, 0x31, 0x30, 0x31 ]

toASCIIString(bytelist)

source code

Returns a string representing a list of ASCII bytes.

bytelist: list of ASCII bytes to convert into a string

returns a string from the ASCII code list

toASCIIString() is the reverse of toASCIIBytes()

example:

toASCIIString([ 0x4E, 0x75, 0x6D, 0x62, 0x65, 0x72, 0x20, 0x31, 0x30, 0x31 ]) returns "Number 101")

toBytes(bytestring)

source code

Returns a list of bytes from a byte string

bytestring: a byte string of the format "3B 65 00 00 9C 11 01 01 03" or "3B6500009C11010103" or "3B6500 009C1101 0103"

toGSM3_38Bytes(stringtoconvert)

source code

Returns a list of bytes from a string using GSM 3.38 conversion table.

stringtoconvert: string to convert

returns a list of bytes

example: toGSM3_38Bytes("@ùPascal") returns [ 0x00, 0x06, 0x50, 0x61, 0x73, 0x63, 0x61, 0x6C ]

toHexString(bytes=`[]`, format=0)

source code

Returns an hex string representing bytes

bytes:  a list of bytes to stringify, e.g. [59, 22, 148, 32, 2, 1, 0, 0, 13]
format: a logical OR of
        COMMA: add a comma between bytes
        HEX: add the 0x chars before bytes
        UPPERCASE: use 0X before bytes (need HEX)
        PACK: remove blanks

example:
bytes = [ 0x3B, 0x65, 0x00, 0x00, 0x9C, 0x11, 0x01, 0x01, 0x03 ]

toHexString(bytes) returns  3B 65 00 00 9C 11 01 01 03

toHexString(bytes, COMMA) returns  3B, 65, 00, 00, 9C, 11, 01, 01, 03
toHexString(bytes, HEX) returns  0x3B 0x65 0x00 0x00 0x9C 0x11 0x01 0x01 0x03
toHexString(bytes, HEX | COMMA) returns  0x3B, 0x65, 0x00, 0x00, 0x9C, 0x11, 0x01, 0x01, 0x03

toHexString(bytes, PACK) returns  3B6500009C11010103

toHexString(bytes, HEX | UPPERCASE) returns  0X3B 0X65 0X00 0X00 0X9C 0X11 0X01 0X01 0X03
toHexString(bytes, HEX | UPPERCASE | COMMA) returns  0X3B, 0X65, 0X00, 0X00, 0X9C, 0X11, 0X01, 0X01, 0X03
