Serial Monitor GIbberish



I’m having trouble getting anything intelligible to appear on the serial monitor. I am using a wildfire v4 board and arduino IDE with the wildfire v3 dual-optiboot board selected. I tried uploading the pre-programmed code back onto the board and hitting the reset button, but I am only getting gibberish on the serial monitor. I believe I have the right COM port and baud rate selected. I have tried it on both a MAC and PC with the same results. I am pretty new to Arduino so I’m guessing I changed something I shouldn’t have.



This does look like a rate mismatch - try the fastest baud rate. Also, while I notice it, choose a line ending - CR/LF.


Switching the baud to 115200 was the trick. Thanks for the help!
