I have a blynk compatible 
Bluetooth device with an SD card.
I want to use the blynk app on my phone to download large blocks of data from a file on an sd card attached to the ino device and then pipe the data up to the cloud. The idea is that someone with the app on their phone can walk up to a beaconing Bluetooth device and connect to it, download an entire data file to the phone, and stream it up to the web. Bonus if each line can be read from the downloaded file and then sent up as a row in a table. Is this at all possible with the current widgets?
I’ve made a sketch and iPhone app to download data from the *ino to my phone in a large text label. I can then copy and paste the data into a spreadsheet or elsewhere. This is very very inelegant.
