Bluetooth Baudrate

[Kiruthika]

We tried transferring data from spresense board to HC05 through arduino platform but the baudrate didn't match. we tried 9600 and 115600 ,we didn't get correct output. Could you please suggest us the correct baudrate for data transfer?

This is the program we gave

This was the output we got for the above program!!!!!!

Hi @kiruthika,

You can try to use a Hardware Serial which is on pins 0 and 1 using Serial2.

Do you have operating voltage set on Spresense to 3.3V? See: https://developer.sony.com/develop/spresense/docs/hw_docs_en.html#_setting_operating_voltage
