How do you communicate with a bluetooth module?

[hankertrix]

The Arduino library seems to have a SoftwareSerial module, which I can't find in this HAL. Are there any examples of working with a Bluetooth module, like an HM-10?

I just need to be able to send text commands from a phone to the Arduino using the Bluetooth module.

Hi,

you can either use a hardware serial which is going to be the most reliable solution. That's just any of the USART peripherals that your chip has available.

If you really want software serial, your best bet is the bitbang-hal crate.

Thanks for your reply. If I understand you correctly, this means that I should connect my Bluetooth module to a USART pin on my Arduino Mega 2560 board instead of a regular pin to have serial communication, and write a function to handle receiving and transmitting data.

Is the above correct? Sorry I am quite new to Arduino development.

Is the above correct?

Yes.

Mostly.

The minor correct is changing "connect my Bluetooth module to an USART pin on Mega 2560" into "connect my Bluetooth module to USART pins on Mega 2560" ( note the plural s )

I am quite new to Arduino development.

And probably also new to electronics. And that is fine. Every Electronics Engineer has been there. (We all start as beginners.) Thing I'm trying to tell is that you are learning many new things. So be ready for many initial failures. Just enjoy the learning experience.

Ah I see. Yeap I am new to electronics as well.

Thank you!
