RDZ_TTGO_SONDE
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
This a simple, experimental, not (well) tested, and incomplete decoder for
|
|
|
|
|
radiosonde RS41 and DFM06/09 on a TTGO LoRa ESP32 with OLED display board.
|
|
|
|
|
|
|
|
|
|
## 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)
|
|
|
|
|
|
|
|
|
|
## 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
|
|
|
|
|
for RS41, a bit less for DMF06/09. 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 (.)
|
|
|
|
|
A DOUBLE press will switch to scanning mode.
|
|
|
|
|
A SHORT press will switch to the next channel in channels.txt
|
|
|
|
|
|
|
|
|
|
# Spectrum mode
|
|
|
|
|
|
|
|
|
|
A medium press will active scan the whole band (400..406 MHz) and display a
|
|
|
|
|
spectrum diagram (each line == 50 kHz)
