Hello @here Please I observe that while working with USART, if I want to transmit data using USB to TTL converter, maybe on Arduino serial terminal or putty, I don’t necessarily need to put carriage return \r, I still receive the data, but when I am using HC05 Bluetooth module, if I don’t use carriage return, I never get data transmitted, any have an idea why it’s that way, I just spent like 40mins debugging
Did you try checking the data sheet of the Bluetooth module? The answer may be there.
Yeah I did @metro04776 thanks man
