Combine XIAO NRF & RemoteXY App
The XIAO nRF52840 microcontrollers from SeeedStudio are ingenious: Tiny, in some cases generously equipped, fast and economical. Ideal for drones and other remote-controlled projects. I don't always want to think up a new remote control or carry an extra device with me. That's why I like to use my smartphone as a remote control, sometimes with WiFi, sometimes with Bluetooth or BLE. RemoteXY is a great app for this, simple and customised.
Unfortunately, the connection between the app and nRF didn't work - until now. And it is so simple to fix.
Supplies
RemoteXY App
and install it on your mobile phone.
Now you can open the webpage https://remotexy.com/ and make your own RC surface. It is very easy.
First do some configuration on the right side (Bluetooth/ nrf based board/ integrated Bluetooth/ Arduino IDE). Then drag & drop joysticks, buttons, sensors, indicators, ... to the center display.
"Get source code" and copy that to your Arduino IDE sketch.
Arduino Software & Libraries
This code from RemoteXY is not working yet. Change in your Arduino IDE code:
to
use in your code this Bluetooth library:
Open library file "RemoteXY.h" with a text editor
My library file can be found here e.g.: C:\Users\x\Documents\Arduino\libraries\RemoteXY\src\RemoteXY.h
Search for the lines
and add another #elif;:
Check, if there are the lines
are somewhere at the end of file RemoteXY.h . Save this file!
Upload your code now to your XIAO nRF52. You can find a very good description of the upload here from the manufacturer SeeedStudio.
Now you can use your XIAO nRF with the RemoteXY app. Happy making!
A Last Tip
By the way:
If the XIAO nRF should disappear from the port list... simply double-click the reset button and it will reappear.
