Would it be possible to add an extra parameter(length) or at least increment to 40 in "send string"?
Now it seems to be 20 chars in length as maximum length.
I cannot look at your chart just now, only on my phone but I think something must not be set correctly.
I send and receive many dozens if not hundreds of bytes over the UART. Indeed if you subscribe to ThingSpeak (for example) that string is about 80 odd characters to update the server.
The case is the same ragrdless the target MCU.
As I wrote above, no matter what I put into function "send string", only ever 20 chars get sent.
But really, its not that big of deal, I have just now redone it as I mentioned, and it works.
Thank you for your feedback though
