[Hilo] Any limitation of file size when Upload and Download file via FTP by Hilo?

Answer: When upload from flash file, no limitation since the file is already existed in flash.
When download and save the data in flash files, then the size limitation is the free space in the flash, please check by < AT+KFSFILE=4,"/ftp">.
If upload from serial link, then no limitation of the size;
If download and transmit data to serial link, then no limitation of the size.
