iOS Question Error decoding data as string

[Deleted member 103]

Hi,

can someone tell me why the function "BytesToString" can not decode the byte "9d"?
Thank you in advance.

Please post code and errors as text instead of screenshots.

I guess that it is not a valid character in Windows-1252 encoding. Is the data actually a string encoded with that encoding?

Never treat raw bytes as string. Use BytesBuilder instead.

This is the first string I get when connecting to a BLE module (AT-09 !!!Android IOS BLE 4.0 Bluetooth module) from Aliexpress.
For all the others that I have used to date, decoding with "Windows-1252" has worked without any problems.
Now I tried to decode with "iso-8859-1" and it works fine.

Never treat raw bytes as string. Use BytesBuilder instead.

Do you think that's better?

Do you think that's better?

The only case where you should convert the data to a string is if the data is actually a string. If not then BytesBuilder is not better, it is the only correct solution.

Thanks Erel! Then I will implement your solution.
