Large-scale data transfer using OSDLP from space to ground and FOTA

Hi there,

I need your help for 2 question about Ground to Space and Space to Ground Communication related to OSDLP.

1st Question:

Is firmware update over the air (FOTA) possible for qubik using OSDLP protocol ?
Can the firmware be sent Ground to Space using OSDLP with Type AD? Is this possible ?

2nd Question:

I have large amount of scientific data (should be fragmented) that needs to be transmitted sequentially to Ground without loss on the satellite side.
Which method should be chosen for big data transfer from Space to Ground?
Is it possible to use OSDLP Type A (as TC)? Or is there any alternative?

Many thanks,
