So far i have been doing projects with Arduino, RPi, ATtiny etc. But now i have project in mind where these things doesnt seem to suit (dont want to use RPi). I need your help. Ok, now on the project: I have a file on my android device (an image and a .ppt file). I want to transfer it to a SD card wirelessly (bluetooth or wifi). I will be providing a USB port to access the data in SD card. Now, i want to assemble/make all the electronics required around the SD card.
(Q1) Which one to choose Bluetooth or wifi (my requirement is only short range, no internet involved) I want to know what bluetooth module should i use (i have read that the HC06 is for SPP and i cannot transfer whole .ppt and do a FTP on that)
(Q2) I dont want to use RPi or any ready made development board, i want to make my own minimum development board. Will this be possible using STM32F103 and do the Bluetooth transfer, if not which platform should I choose and how to make my own dev board? Please get me started on this
