How to convert received ASCII data to a value

Hi, I am developing an android app using app inventor for micro:bit. I have tried to acquire ldr value readback through bluetooth UART write command. The data does show in my andriod app but it is in ASCII form. For an instance, the data is [50,49,51] which actually means 213 in decimal. May I know how should i write in the app inventor block code so that i can convert the data to a value from the ASCII format stated above? Thanks in advance for your patience and help.

How to convert received ASCII data to a value

Now that I understand the game, here is the map/reduce version, generalized to all text, based on @Italo's ASCII conversion: AsciiCHRASCprocedures.aia (4.4 KB) [make_string] [make_string_test_capture]

you can use the AsciiConversion.aix extension https://community-appinventor-mit-edu.ezproxy.canberra.edu.au/uploads/short-url/pfdDefFQUxeffRFScKY8ifXfoVK.aix

and call the Conversion function passing the list of ascii codes as parameters. This function will return the text corresponding to this list

here is the documentation of the extension

I think this extension makes the code too easy
