Tamás, that will happen if the crash occurs during the SD write operation. An option to minimize this is writing to a temporary file first and renaming that after completion, but that won't help if the crash occurs during the rename. A journalling file system would solve this, but afaik there is none available yet. I think I'll change the code to use a temp file, that should help in most cases. But crashes also are very infrequent now. Regards, Michael Am 15.02.20 um 17:18 schrieb Tamás Kovács:

I installed this plugin with the optional code to store the history, I set the sd card for history file, everything work fine until crash, After the the history file is empty. I use the plugin in a Peugeot iOn (mi vehicle type).  This is plugin problem or the problem in the car code?
