Answer 1

After installing v4 of Smart Remote Control on A7ii I can now list the contents of SD Card and download RAW files and image previews. The sequence is roughly

1 move camera to recording mode (API does not work before this)

POST http://192.168.122.1:8080/sony/camera
{ "method": "startRecMode",
"params": [],
"id" : 1,
"version" : "1.0"}

2 move camera to contents transfer

POST http://192.168.122.1:8080/sony/camera
{ "method": "setCameraFunction",
"params": ["Contents Transfer"],
"id" : 1,
"version" : "1.0"}

3 list the images

http://192.168.122.1:8080/sony/avContent
{"method": "getContentList",
"params": [{
"uri": "storage:memoryCard1",
"stIdx": 0,
"cnt": 500,
"view": "flat",
"sort": ""}],
"id": 1,
"version": "1.3"}

There is new Camera Remote SDK v2.20
