I just started working on a project involving bluno beetle ble. For now, i'm sending the data from beetle to a android app i made.
But, for a fail safe mechanism in case the mobile is not in range or has disconnected from the device, i want to add a SD card reader to the device so i can save the data.
Is it really possible to add SD card reader to beetle ble? If yes, can someone provide any hint on what connections need to be made?
