What will aioble scanResult.name() report for an advertisement containing unprintable characters?

[brianreinhold]

I have device that is sending the following advertisment

0f 09 31 53 43 31 30 30 00 00 00 00 00 00 00 00 03 19 00 00 02 01 06 03 03 02 78

Note the device name

0f  // length of data including code
09 // adv code indicating device name
31 53 43 31 30 30 00 00 00 00 00 00 00 00 

The name has a whole slew of unprintable null characters at the end. What will ScanResult.name() return? Is it
1SC100 or 1SC100 (replace the nulls with spaces 0x20)?

ScanResult.name() will interpret (decode) the name as UTF-8 string using str(name,'utf8'). The trailing nulls will remain as null characters at the end of the string. To be sure to have the "ascii only" characters, replace the nulls by "":

>>> advertised_name=b'1SC100\x00\x00\x00\x00\x00\x00\x00\x00'
>>> name_as_string=str(advertised_name,"utf-8")
>>> name_as_string
'1SC100\x00\x00\x00\x00\x00\x00\x00\x00'
>>> trimmed_name=name_as_string.replace("\x00","")
>>> trimmed_name
'1SC100'

@bixb922 I ended up doing that - actually I used
trimmed_name=name_as_string.replace('\0', '')
but it seemed to work. Maybe both are valid?

Perfect, both are valid!
