How do you Convert Binary to Text in MIT App Inventor?

So where are you getting all these text 1s and 0s from?

24

I've made an emitter where the text gets encoded, and now I'm trying to decode it, the code I've used for sending is above, you can check it out if you need to. THX :slight_smile:

I'm trying to download the csv file but couldn't at the moment.

This is the one in my aia

binchar.csv (681 Bytes)

Hello everyone,

First of all, I want to thank the community for the previous help I received in implementing the decoding part of my project. Thanks to that, the decoding process is now working perfectly.

Now, I need assistance with a different part of the project. I am trying to format a binary string so that every 8 bits are grouped and separated by a space.

Explanation: Given a binString of length n (at the final project, it will recieve sequences of bits every time it is working), I want to:

  1. Insert a space every 8 bits to keep the structure intact.
  2. Ensure that no segmentation errors occur.
  3. Handle cases where the string length is not a multiple of 8.

:small_blue_diamond: What I Need Help With

Sequence received
"111111110100110101100001011100110110100101101110110011"

Sequence expected
"11111111 01001101 01100001 01110011 01101001 01101110 110011"

What I received
"111111 10100110 1011000010110000 10111001 001101"

  • Making sure the script correctly groups exactly 8 bits per block.
  • Preventing out-of-range errors when the length is not a multiple of 8.
  • Ensuring the final result is correctly formatted.

I appreciate any help! Thank you in advance! :blush:

The project I'm working with:
binaryToText2.aia (4.9 KB)

How it should works:

  1. binString = "01111111 10100110 10110000 10111001 00110100 10110111"

  2. binString = "011111111 10100110 10110000 10111001 00110100 101101111"

  3. binString = "11111111 10100110 10110000 10111001 00110100 10110111"

  4. binStringList = ["11111111", "10100110", "10110000", "10111001", "00110100", "10110111"]

If you click on the blocks above to make them full size, you can drag them onto your project.
