RTTY and LoRa High Altitude Balloon Tracker for Arduino and SX127x
Plug and Play RTTY and LoRa High Altitude Balloon Tracker for Arduino and SX127x (or Hope RFM9x).
TBTracker is a sketch for a tracker for high altitude weather balloons. It will send telemetry data in RTTY and LoRa format.
It is designed to send telemetry data in the correct format for https://tracker.habhub.org/
It can send data in RTTY or LoRa format on different frequencies and with different callsigns.
Currently it supports:
The code as is, is for the SX1278 module. If you have a SX1276, then change line 5 in radio.ino. See the comments in that file.
You will need two extra Arduino libraries to be able to compile this sketch.:
https://github.com/jgromes/RadioLib (Radiolib, use version 5.5.0 or lower to overcome out of memory errors if you are using an Arduino mini)
https://github.com/mikalhart/TinyGPSPlus (tinyGPS++)
To run this, you need a TTGO T-Deer board or:
Note that currently setting different flightmodes in uBlox GPS modules is not supported. This could cause GPS failures above 18km when using uBlox GPS modules. I recommend using the ATGM336H GPS modules.
Connect the T-Deer as an Arduino Mini to the Arduino IDE.
Many parameters are user adjustable in settings.h
The Arduino Pro mini has a rather small memory capacity. If you run into memory issues, consider disabling RTTY or LORA in the settings.h file.
Also disabling DEVMODE in settings.h will free up a lot of memory at the cost of no serial output.
Have fun,
Roel.
