I'm looking for the terminology/possiblity having my Arduino gathering data to a SD card up in a tree, (solar powered) then switching my phone over to tethering/becoming a access point, then my phone downloading/Arduino uploading the data. Obviously when Arduino is connected to phone it doesn't have to record any data, but then must wipe once uploaded.
Ideally also time sync when connected to the phone, I think I have read you can get a time by connecting Arduino to a IP address like talking clock or something rather then using a battery time module thing.
Scope of project is to measure wind speed up a tree every 5-10 minutes, store the data, me to arrive once a week without having to climb the tree, download the data, wipe, start again. Also only look for WiFi mid day every Tuesday or something to save on battery.
Looking for possibilities/likelihood and technical terms for anything of the above to help on my Google searches. Arduino upload data WiFi is giving me a lot of upload sketches over WiFi hits.
