Serial difference between Arduino Uno and Pro mini

Hi,

I'm starting with Arduino and love it! I'm interfacing with a GPS module that works on 9600b. This works with the Arduino Uno on pin 6 and 7, the tinygps test example works, and the serial monitor prints a lot of stuff. If i upload the same code to the Pro Mini, i notice two strange things: i only receivce readable messages when i select 57600 baud. In code i used Serial.begin(115200);.

If i change this to Serial.begin(57600); i don't receive back any information.

When i set it back to 115200, and turn the serial monitor on 57600 i see that the Pro Mini doesn't get serial information.

Has this behaviour something to do with limitations of the Pro Mini? Or am i missing something here?

Kind regards, John

The baud rate should be the same for the serial monitor as it is for the serial device sending serial information...

Well it's fixed, after again searching the interwebs i found that if you select the wrong board type, you could get such strange behaviour. :blush:
