- Correctly decode DMF06 (thanks to Chrischan for test sonde!!!) - Touch button support (in particular for v2 boards with "real" button) now its sufficient to just touch one of the pins of a v2 board - Multiple displays (inspired by DL2MF's modifications) - Wifi mode 2 (AP2) fixed missing initialization of mDNS (http://rdzsonde.local) - updated OTA URL (my.to domain unfortunately expired) - millis() call removed from ISR (/1000 on uint64_t type in millis causes library function call not marked as IRAM_ATTR, causing crash in some cases - edit files on file system (http://rdzsonde.local/edit.html?file=xyz.txt) (use with caution, no checks for buffer overflows) Some TODOs pending for next release version - sending AXUDP to aprsmap currently disabled - RX loop a bit too slow (in particular with AXUDP enabled), causing loss of RX frames due to SX1278 overflow. Needs some redesign in SX1278 handling. - display layout editable via config file |

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.
There have been made some additions for TTGO LoRa ESP32 with only RST button. Please check also your OLED port settings, both versions use different ports. You can setup the depending ports in config.txt, OLED Setup is depending on hardware of LoRa board
- TTGO v1: SDA=4 SCL=15, RST=16
- TTGO v2: SDA=21 SCL=22, RST=16
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) 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
