Bluetooth Shield Project

[RXB974]

Hello,
I'm currently using the Adafruit Bluefruit LE Shield on Arduino Mega2560. They are both connected via stacked headers.

To test the product, I have used the example "atcommand" code.
I have altered the SPI pins accordingly (pins 50-52 for MISO, MOSI and SCK respectively).

Still, every time I'm trying to run the code, it cannot do a factory reset.
When trying, the serial monitor creates a string "⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮". It's repeated every couple of seconds for at least a minute.

The shield itself blinks red near the MODE led, if that helps.
I have no clue what am I doing wrong, any help would be welcome!

That looks like a Serial baudrate mismatch.

As a sanity check, make sure your Serial Monitor matches the baudrate in your code.
