Sending data to smartphone via bluetooth

Using Arduino Programming Questions
1

Hi everyone!

Me and 2 friends are very new to Arduino and Bluetooth, yet have experience in programming and electronics, so we're not completely useless :slight_smile:

We want to send data to the smartphone app Serial Bluetooth Terminal. As a first step, we're trying to send anything at all just to test it out. In the next step, we want to send data from a sensor.

We are using Arduino Nano 33 BLE, and so far we have managed to connect the phone to the board. But we simply cannot get anything to be sent over. We have used several tutorials, chat GPT, you name it...

Please, can anyone help us out? Do we need the HC-05 bluetooth modul and a different board, like the Uno? We ordered the Nano 33 BLE because we thought it would cover the Bluetooth functionality.

Any code would be greatly appreciated!

Thanks a lot in advance!

This forum isn´t a coding service department.

My standard advice:

Keep asking the robot until he/she/it gives you the correct result you expect.

One answer could probably be 42.

BLE is Bluetooth LowEnergy and that is different from (and not compatible with) the classic Bluetooth of modules like HC05 or HC06. Your PC needs to be BLE compatible (Apple). Unfortunately I don't know much about BLE so can't help wit that.

If you want to use classic Bluetooth then you should be able to interface your NanoBLE with a HC05 to get classic Blurtooth.

Thank you so much for trying to help, then I think we'll order a HC05.

That is fine. It is up to you when you have the information that you desire.
