Read SD card data
Posted: Tue Sep 11, 2018 9:54 pm
Hello everyone!!
I am working with freematics one+, I am modifying the datalogger sketch and I would like to read data from the sd card and then send it via bluetooth to the smartphone.
I already know how to code the bluetooth server. It would be amazing if someone can tell me how to start to read from the sd card.
Thank you so much!!
