BLE WriteStrings issue

I use the last extension of the BLE 20200828
I try to use WriteStrings command to send over characteristic a string "on"+LF
So I send "on\n", but doesn't works.
In the other hand I tried WriteBytes, and I write a list of (111,110,10), and this command works perfectly.
I send each ASCII caracter, ans no problem.

So I think there is an issue using writestrings. So please help me.


Hello Julien

It depends on what is receiving the string.' \n' normally signals "end of data", but you appear to include it for another purpose?
