Download the checksums file for your platform from the same release as the app. Calculate your file’s SHA-256 hash and compare it with the entry for that exact filename.
macOS terminal
shasum -a 256 "YOUR_DOWNLOADED_FILE"Windows PowerShell
Get-FileHash -Algorithm SHA256 "YOUR_DOWNLOADED_FILE"Replace YOUR_DOWNLOADED_FILE with the actual path. On Linux, use sha256sum "YOUR_DOWNLOADED_FILE". App releases include checksums-macos.txt, checksums-windows.txt, checksums-linux.txt and checksums-android.txt. A matching checksum confirms agreement with that file; it is not an independent signature of its publisher. Handheld releases provide SHA256SUMS.

- Plug the node in over USB. Close other apps that use its port, such as Ratspeak or a serial monitor.
- If you just installed, press RESET on the board first.
- A Repeater answers status over USB, and so does an RNode that another app is using.

rsNode settings
Requires firmware with USB settings support. Read the node's settings, change them here, and save. Saving restarts the node. Region, LIMITS and the radio are set on the device.
Before you read
- Plug the node in over USB. Close other apps that use its port, such as Ratspeak or a serial monitor.
- If you just installed, press RESET on the board first.
- An RNode another app is using over Bluetooth or Wi-Fi shows its settings but saves none: disconnect that app, or hold USB on the node.
