Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi all.

What is the maximum filename length on the CMM2G2 with the latest FW from Peter?
How long can the filenames be on the SD card?

RC4 page 94, 127 for files and directories.

For FAT32 file names 255 so the CMM2 limit of 127 applies.

For anything sensible, 8.3 in caps only. :)
