root@TinaLinux:/mnt/UDISK/gattlib/build# ./examples/read_write/read_write DC:2C: 26:01:E2:27 write fb349b5f-8000-0080-0010-0000f1ff0000 0x1234 Value to write: 0x1234 Fail to find handle for UUID. Could not find GATT Characteristic with UUID 0000fff1-0000-1000-8000-00805f9b34fb

why return Could not find GATT Characteristic with UUID 0000fff1-0000-1000-8000-00805f9b34fb? I write to fb349b5f-8000-0080-0010-0000f1ff0000, but return 0000fff1-0000-1000-8000-00805f9b34fb, why?

I did some investigation and it looks like your issue is related to Big-Endian support. Probably the main file to change for adding Big-Endian is https://github.com/labapart/gattlib/blob/master/dbus/bluez5/lib/uuid.c I do not have Big-Endian hardware with me.

If you want me to add Big-Endian please contact me through https://labapart.com/about/
