Hello everyone,
I'm creating a project that sends phone number to arduino when message is received using app inventor.
The problem is that number contains spaces(like +12 12345 67890) but i want the number without spaces (like 1234567890).
Can you please help me?
Thank you
Your subject line says Dusplaying phone number in app invenyorr, yet you mention sending phone number to Arduino. Confusing.

Whichever way it’s going, you always send a string character-by-character.
So, as you process each char in the source string, check whether it’s a digit before sending it on, otherwise skip it, and process the next.
