Troubleshooting

So i got this code to flash to my particle boron device. but they mentioned functions like ‘-’ or ‘+’ to raise volume for example. Where can i run this code? i tried serial monitor, i tried a couple of websites. Please let me know as my speakers need some good code

@talalgedeon, serial monitor doesn’t send keystrokes to the device so you should use a terminal program like TeraTerm or PuTTy to connect to the device. Then, you will be able to send commands to the device using your keyboard.

3

How would that work? because i am looking at Puttys documentation, but what does ssh mean, how should can i configure it to send keystrokes is there any helpful guide for the particle devices and mac's terminal

4

You don’t want SSH (which would be googlable what it means :wink: ) but Serial and once your PuTTY has connected to your device you just hit the key you want to send.

Hahaha yes thats what i did but i didnt really understood what it means. is there any tutorial that can help lead me to the solution im looking for. i cant seem to find anything for mac

I’m not a Mac person, but IIRC CoolTerm for Mac should be capable of doing what you want.
For other applications you can google for serial terminal for mac and I’m pretty sure there will also be videos to show how to use these applications.

I use this and it works fine on all particle devices.
