Hello friends,
I'm new with arduino and maybe my doubt is very easy for you.
I'm trying print in a android app temperature mesured via Max6675 on arduino connected with a HC-06 Bluetooth device . It works fine when i use the serial monitor on arduino ide at the pc, but at the app it show only some crazy values.
I tried to change the baud rate but it didn't work.
Please, help me!
best regards,

daniel

Bluetooth is simply serial without wires. If your code works correctly with the serial monitor, than the errors are on the phone app side.

One thing I can see from you image is that the value of TREAD is being displayed as the ascii values 51 48 46 50 53 instead of the chars 30.25.
