tone() Not working with Nano 33 BLE

[brendansmallco]

Hi Team,

Code implemented for the nano v3.0 does not work with the Nano 33 BLE.

`const int buzzer = 7; //buzzer to arduino pin 9

void setup(){

pinMode(buzzer, OUTPUT); // Set buzzer - pin 9 as an output

}

void loop(){

tone(buzzer, 1000); // Send 1KHz sound signal...
delay(1000); // ...for 1 sec
noTone(buzzer); // Stop sound...
delay(1000); // ...for 1sec

}`

Tried to manually import the Tone Lib but gave errors. Any idea what the issue is?

This issue has already been fixed by arduino/ArduinoCore-nRF528x-mbedos#59 but there hasn't been a release of Arduino nRF528x Boards (Mbed OS) since that time. If you do want to test out the fix, there is a beta release you can try:

1. (In the Arduino IDE) Tools > Board > Boards Manager
2. Wait for the download to finish.
3. From the list of platforms, select "Arduino Mbed OS Boards (nRF52840 / STM32H747)".
4. Click the "Install" button.
5. Wait for the installation to finish.
6. Click the "Close" button.

In the Tools > Board menu, you will now see two different "Arduino Nano 33 BLE" options. The original one is under the "Arduino nRF528x Boards (Mbed OS)" section, while the beta test one is under the "Arduino Mbed OS Boards (nRF52840 / STM32H747)" section. If you select the Nano 33 BLE board option from under the "Arduino Mbed OS Boards (nRF52840 / STM32H747)" section" section of the menu and then upload your sketch to your Nano 33 BLE, I think you'll be happy to hear your buzzer beeping away.
