BLE Camera Application Video transfer

[Ziyao Zhou]

Hi 

I want to use BLE to send out realtime videos, and I found there is a nrf70-wifi-ble-image-transfer-demo given by nordic. Could you show me what is the BLE Camear App to connect. And whether there already has a demo for only BLE transfer. Thanks a lot!

Hi

The camera "app" is a script that is running on the computer as mention here. As far as I can see the application repo you have the app_blueooth.c which seems to do some image sending. I would recommend to start there, as far as I know we don't have any other example for sending images over BLE for the NCS SDK

Thank you for your reply! I notice this app is only available for WiFi, what about BLE app, is it this one？

By the way, if I am using SDK 2.9, how could I patch and add the driver. What is the arducam_mega_support.path?Where to copy it. I didn't seen such file in the folder.

Hi, 

I think that app is for an older sample based on the old SDK. The demo you linked to uses the python script running on a computer as mentioned. 

You can add the patch in the same way as mention in the documentation for sample as it is not a part of Zephyr. The patch add the driver to your zephyr project.

Hi

I have tried to do so and found that I cannot generate those drivers.

Could you kindly teach me how to do that?

I tested myself, it seems like it is not compatible with NCS 2.9. This might be due to changes with sysbuild that was first introduced with NCS 2.7. 
As we do not provide any support for the arduino playground samples I would either recommend to use NCS 2.7 if you want to use that sample.
You can have a look at this driver https://github.com/arribada/arducam-driver-zephyr/pull/8/commits it seems like there has been some work done with it last yaers which might make it work with newer version of NCS

Hi, I am using the ncs 2.7 but still cannot. Is there any command problems?

[runsiv]

It seems like the patch was added to me, I think the white space is only a warning

Also you need to use the corresponding toolchain to the sdk version
