Freematics ONE+ arrived today. Loaded the datalogger sketch (V5). File is created on the SD card but no data is written.
Read through the forum and can't find a solution.
Please advise........
SD card is empty?
Re: SD card is empty?
I had a similar problem. From my experience with my device... take it for what it is, not sure how helpful it'll be to others, or it can just might be a user error and I didn't do something right and it just happens that by removing the SIM card this seems to have fixed the "sd card" being empty for me.
The sketch I was using does not have GSM options configured. But the card was in the slot anyway(thinking it wasn't an issue) and essentially what ended up happening was that during the boot process, it never finishes all the validation and just hangs.
