How to download RAW files from A7 API?

Question

I am working on a simple desktop tethering app for my A7 using the Wi Fi based JSON API.

https://developer.sony.com/develop/cameras/

All works well except I cannot download the RAW files. I can tweak things to get full size JPG file which seems to be served from the file system on the camera. for example the following URL seems to address the JPG from SD card.

http://myA7camera.info:8080/postview/memory/1000/DCIM/100MSDCF/DSC01353.JPG

This URL is coming back from actTakePciture call (I had to give the camera real like URL to satisfy stackoverflow posting requirements. In reality it is the camera IP addresss there). However although the camera is set to deliver RAW+JPEG and RAW file indeed is written to the card, the file is not accessible to download. I tried changing the extension.

I tried also plugging the camera into USB while working through API to be able to detect new files via filesystem monitoring and download them while controlling the camera via Wifi - no luck - USB connection terminates the Remote Camera Control App.

As well I cannot set the camera into RAW only mode while in the Remote Control App.

I browsed the "guide" and "accessControl" API facets but these do not seem to yield file download locations....

Any clues or ideas how to get my hands on the RAW files? Would be great to have tethered shooting via Wifi and Lightroom, no?

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
