I recently downloaded CubeMX for the F7 again, to check for the LL headers.
I'm pleased to find them complete now, at least at first glance. Gonna test it in the next time.
But to my suggestion. The whole packet was almost 700 MByte, for perhaps less than 1 MB wanted content.
Couldn't you ST guys make the LL header stuff a separate download package ?
For my part, even additionally to CubeMX.
Albeit I'm afraid there is not much inter-mixture between Cue users and LL users.
