Here is the project, I have a raspberry connected via GPIO to the arduino. The arduino is compiling a list of data via a text file on the sd card (sensors and what not). I can send data TO the arduino. But once the text file is created on the sd card, I can not then see the sd card (on the arduino) from the raspberry to copy it or even SEND the text file to the raspberry.
Solutions: 1: (Preferred) to be able, from the raspberry, to see the arduino sd card and copy/move the text file to the raspberry for processing. 2: send the text file from the arduino (via gpio) to the raspberry sd card into a protected directory for processing after XX time.
We have been fighting this for some time and are hitting a brick wall. Does anyone have a suggestion?
