============
|
|
|
|
This a decoder for radiosonde RS41, RS92, DFM06/09/17, M10/M20, and MP3H
|
|
based on a TTGO LoRa ESP32 board.
|
|
|
|
It supports OLED displays (SSD1306, SH1106) and TFT displays (ILI9225, ILI9341/9342).
|
|
|
|
It also supports feeding data to external applications using WiFi (NOT bluetooth):
|
|
- Android app by dl9rdz (see https://github.com/dl9rdz/rdzwx-go for apk download)
|
|
- AXUDP (for aprsmap application by oe5dxl, among others)
|
|
- KISS TNC (aprs format, mainly useful for APRSdroid app)
|
|
- MQTT
|
|
- SondeHub tracker
|
|
- Chasemapper UDP (experimental)
|
|
|
|
|
|
Please consult the Wiki at https://github.com/dl9rdz/rdz_ttgo_sonde/wiki/Supported-boards
|
|
for details on supported boards, and additional setup instructions.

SondeHub integration has mainly been tested with RS41 and DFM.
|
|
|
|
|
|
Support for other radiosondes that use AFSK modulation is not feasible with the TTGO hardware.
|
|
In particular, decoding iMet-1/iMet-4 radiosondes is not practical (iMet-5x seems to use FSK,
|
|
so should be feasible to implement).
|
|
|
|
Adding support for LMS6 (see issue #48) and ims100 (see branch ims100) could be feasible,
|
|
but currently I don't have plans to do add this myself. Well-tested pull requests will of
|
|
course be considered for inclusion :-).
|
|
|
|
## Installation
|
|
|
|
You can download the latest binary automated build for the development and testing branches [here](http://rdzsonde.mooo.com/download.html), the binary includes everything including configuration files so any existing settings will be reset.
|
|
|
|
To update an existing installation to the latest development or master version you can use the [OTA](https://github.com/dl9rdz/rdz_ttgo_sonde/wiki/Other-features#over-the-air-updates) update feature.
|
|
|
|
The downloaded .bin file can be flashed to your ESP32 board using [esptool](https://github.com/espressif/esptool) or [ESP32 Download Tool](https://www.espressif.com/en/support/download/other-tools)
|
|
|
|
### esptool
|
|
|
|
You can run the following command replacing `<filename.bin>` with the path to the downloaded .bin file.
|
|
|
|
If you encounter errors with the device COM not automatically being detected replace `/dev/cu.SLAB_USBtoUART` with `COM<X>`.
|
|
|
|
```
|
|
esptool --chip esp32 --port /dev/cu.SLAB_USBtoUART --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x1000 <filename.bin>
|
|
```
|
|
|
|
### ESP32 Download Tool
|
|
|
|
The binary file can also be installed using the GUI application with the [following](http://rdzsonde.mooo.com/) settings.
|
|
|
|
## Button commands
|
|
|
|
You can use the button on the board (not the reset button, the second one) to
|
|
issue some commands. The software distinguishes between several inputs:
|
|
|
|
- SHORT Short button press (<1.5 seconds)
|
|
- DOUBLE Short button press, followed by another button press within 0.5 seconds
|
|
- MID Medium-length button press (2-4 seconds)
|
|
- LONG Long button press (>5 seconds)
|
|
|
|
You can optionally use a second button, which you have to add manually to your board.
|
|
See https://github.com/dl9rdz/rdz_ttgo_sonde/wiki/Hardware-configuration for details.
|
|
|
|
|
|
## Wireless configuration
|
|
|
|
On startup, as well as after a LONG button press, the WiFI configuration will
|
|
be started. The board will scan available WiFi networks, if the scan results
|
|
contains a WiFi network configured with ID and Password in networks.txt, it
|
|
will connect to that network in station mode. If no known network is found, or
|
|
the connection does not suceed after 5 seconds, it instead starts in access point
|
|
mode. In both cases, the ESP32's IP address will be shown in tiny letters in the
|
|
bottom line. Then the board will switch to scanning mode.
|
|
|
|
## Scanning mode
|
|
|
|
In the scanning mode, the board will iterate over all channels configured in
|
|
channels.txt, trying to decode a radio sonde on each channel for about 1 second.
|
|
If a valid signal is found, the board switches to receiving mode on that channel.
|
|
A SHORT buttong press will also switch to receiving mode.
|
|
|
|
## Receiving mode
|
|
|
|
In receiving mode, a single frequency will be decoded, and sonde info (ID, GPS
|
|
coordinates, RSSI) will be displayed. The bar above the IP address indicates,
|
|
for the last 18 frames, if reception was successfull (|) or failed (.), or had
|
|
some errors (E), e.g., CRC check failed.
|
|
|
|
A DOUBLE press will switch to scanning mode.
|
|
|
|
A SHORT press will switch to the next channel in channels.txt
|
|
|
|
A SHORT press on the second button will switch to a different display screen.
|
|
|
|
## Spectrum mode
|
|
|
|
A medium press will active scan the whole band (400..406 MHz) and display a
|
|
spectrum diagram (each line == 50 kHz)
|
|
For TTGO boards without configurable button there are some new parameter in config.txt:
|
|
- spectrum=10 // 0=off / 1-99 number of seconds to show spectrum after restart
|
|
- timer=1 // 0=off / 1= show spectrum countdown timer in spectrum display
|
|
- marker=1 // 0=off / 1= show channel edge freq in spectrum display
|
|
|
|
