Problems with sending a string over RS232

[Wolfgang Kos]

I have problems with sending a string to Bluetooth Modul via RS232 like this:
This will not function:
I will adding 3 Strings to 1 String like this:
SEND_WERT11 = PC_Modus11 + WERT_11 + RETURN
The code will not function:
FCD_047b2_RS232_BLE__SendString(FCV_SEND_WERT11, FCVsz_SEND_WERT11);

This is function fine with 1 string:
FCD_047b2_RS232_BLE__SendString("SUW,12345678901234567890123456789011,1234\r\n", 44);

Here the 3 strings:
PC_Modus11 = "SUW,12345678901234567890123456789011,"
WERT_11 = "1234"
RETURN = "\r\n"


In the log i can see Infos over' FCI_SHEAD'

What is the error?
Thank you for all infos.

Hi,
String concatenation has issues/bugs when more than two are added.
So please try to do this in more steps,
e.g.
String = A
String = String + B
String = String + C
