Hello! For a project I was going to build an avionics section for model rocketry. I was wanting to add sensors and be able to write that data from them into the serial port, but of course, it cant be plugged in when in powered flight. So I was wondering what would be the best radio that I could use to communicate between the Arduino in flight and my computer, and how I would go about connecting that. I was also wondering for if I loose connection between them for some reason, how I could take the data and write it on a physical storage device aboard the rocket (sd, flash chip, etc...).
Im not sure if this is crucial information or not, but the scale of this rocket would be about 4ft in height.
Unless you can do something with the data while in flight it would be easiest to record the data onboard and download it on recovery. Onboard storage would depend on the amount of data. If it is a small amount use a classic Arduino (AVR based) and store in EEPROM. For larger amounts of data use an esp8266 and store it in the flash file system.
I was wanting to use the data in flight so that i can know what is happening with the rocket internally mid flight than just visually. Thats what I was wanting to do. And I also want to have wireless communication with it not only for data, but also pre flight, and like uploading before launch, and also to interrupt the vehicle if needed like an abort if everything goes absolutely wrong. Its also good incase the rocket fully fails and the data on board gets lost. Just a backup.
