STM32 (f103c8t6) blue pill char length larger then 255 won't work #105

Hello everyone, please help. The problem is this: a char array cannot be larger than 255, why? Here is an example: .... if (Serial.available() > 0) { char incoming[400]; Serial.readBytes(incoming,400); Serial.println(incoming); } .... So, when I send ower serial text that is, for example, 350 characters long, serial read only 255. if I make: .... if (Serial.available() > 0) { char incoming[400]; String string=Serial.readString(); Serial.println(string);

string.toCharArray(incoming,400); Serial.println(incoming); } ....

now String works perfect but char is limited to 255. Thanks in advance.

Which IDE do you use for compiling your sketch? Which OS are you using on host? How do you send the data to bluepill? Which serial monitor?
