Trying to decide on whether or not to use bluetooth/Android app or wifi/SD for my project
My options are
-
Bluetooth - to - android app - try and use SQLite to export to CSV
-
Wifi w/SD Shield to Blynk or database website so i can CSV the data.
Ultimate goal is get into excel for graphing/logging. Eventually want all devices I create to log data to Access database.
Which option would be easier/optimal? Mind you some users may not have Wifi and also I dont know how to do an android app (working on it tho).
If you were getting performance data from an electronic to your phone or to a server, etc. SD for backup purposes
