I am having a presentation model with pdf files as blob. i need to communicate with the rhoconnect and save blob in device. Please help me to get started.
Here are the docs to get you started:
Basically, you can not send the blob to rhoconnect directly from the backend - it won't be stored in Redis. What you can do is to send the blob url as one of object attributes - and then, device will download it directly from the url during the sync. This implies that url needs to be accessible from the device.
