SubGHz Radio
Note: This panel only appears on Free Wili boards built with the CC1101 sub-GHz radio installed; it won't show up on boards without that hardware option.
Found under Wireless on the device's panel list.
Sub-GHz Radios
The Sub-GHz application is intended for receiving, recording, analyzing, and transmitting signals with the onboard CC1101 radios.
Availability
CC1101 panels are not included in the current FreeWili 2 firmware release. Selecting Wireless > SubGHz may therefore open an empty screen. Use Home to return to the launcher.
The separate LoRa application is available and uses the WIO-E5 radio. See its help page for receiving and sending LoRa data.
When CC1101 support is enabled in a future release, this application will provide these tools:
- Read received packets
- Capture raw signals
- Transmit saved
.subfiles - Scan signal strength by frequency
Radio transmission is regulated. Only transmit on frequencies and at power levels permitted in your location.
Sub-GHz Receive Log
This panel is designed to show packets received by either onboard CC1101 radio. A received packet includes its data, signal strength, link quality, and CRC result.
Controls
| Button | Action |
|---|---|
| Gray | Send a test packet |
| Yellow | Switch between Radio 1 and Radio 2 |
| Green | Clear the log |
| Blue | Return to the Sub-GHz menu |
| Cancel | Open this help page |
Availability
The CC1101 application, including receive logging, is not included in the current FreeWili 2 firmware release. See Sub-GHz Radios for availability information.
Sub-GHz Raw Capture
Raw Capture records Sub-GHz pulse timing and saves it as a .sub file on the
SD card. Use the configuration view to choose the frequency, radio preset,
capture duration, and output name before recording.
Controls
| Button | Action |
|---|---|
| Gray / Yellow | Move through configuration fields |
| Center | Edit the highlighted field |
| Green | Start or stop capture |
| Blue | Return to the previous view |
| Red | Open or close configuration, as labeled |
| Cancel | Open this help page |
Keep the device close to the transmitter during capture. A clean recording usually contains one or more complete button presses with a short quiet period before and after them.
Availability
The CC1101 application is not included in the current FreeWili 2 firmware release. See Sub-GHz Radios for availability information.
Sub-GHz Signal Files
This panel lists saved Sub-GHz signal files from the /radio/ folder on the
SD card. Selecting a file opens it in the transmit panel; it does not transmit
immediately.
Controls
| Button | Action |
|---|---|
| Up / Down | Move through the file list |
| Center | Open the highlighted file |
| Blue | Return to the Sub-GHz menu |
| Cancel | Open this help page |
Files must use the .sub format. If the list is empty, confirm that the SD
card is mounted and that the files are stored in /radio/.
Availability
The CC1101 application is not included in the current FreeWili 2 firmware release. See Sub-GHz Radios for availability information.
Sub-GHz Transmit
This panel transmits the signal stored in the selected .sub file. The
screen shows the file name, radio settings, and transmit status.
Controls
| Button | Action |
|---|---|
| Gray | Transmit once |
| Yellow | Change the repeat count |
| Green | Start or stop repeated transmission |
| Blue | Return to the signal-file list |
| Cancel | Open this help page |
The frequency, modulation preset, protocol, and signal data come from the selected file. A malformed or unsupported file is rejected without sending.
Availability
The CC1101 application is not included in the current FreeWili 2 firmware release. See Sub-GHz Radios for availability information.
Radio transmission is regulated. Only transmit signals you are authorized to use, on frequencies and at power levels permitted in your location.
Sub-GHz Frequency Analyzer
The Frequency Analyzer scans supported Sub-GHz frequencies and plots received signal strength. Use it to find active channels before opening a receive or raw-capture panel.
Controls
| Button | Action |
|---|---|
| Gray / Yellow | Change the highlighted scan setting |
| Green | Start or pause scanning |
| Blue | Change the frequency range or layout, as labeled |
| Cancel | Open this help page |
| Home | Return to the launcher |
A taller or brighter peak indicates a stronger signal at that frequency. RF noise can also produce peaks, so repeat the scan while operating the transmitter you want to identify.
Availability
The CC1101 application is not included in the current FreeWili 2 firmware release. See Sub-GHz Radios for availability information.
