BLE OTA by BLE connection not by DTM mode

[Johnnywen]

Hi Asbjørn，

As I mentioned in case 352770

We are in same question as the  initial question issued by our colleague RongLinQin. As I mentioned, we want to conduct BLE OTA no based on DTM mode but using BLE connection. we can not do anything for Soft Device, so just try to implement it on app layer, but still fail to do that.

So, we are not sure  if you could help give some instructions about how to do that on app layer if Nordic do not want to change anything in soft device for that.

Thanks a lot

I would like to give some more information, what I mentioned is BLE OTA testing,that is, RF performance testing, not means DFU, thanks.

I can see you are working on the nRF5 SDK, unfortunately I think it's unlikely we will do changes at this time in the softdevice controller that allow what you request. If you are already in contact with Nordic in other ways (e.g. e-mail or teams) then I suggest you continue discussion there.

Hi Kenneth,

As I mentioned, we are checking this issue in ticket 352770 

And Nordic engineer request to create a new ticket for it,

If Nordic can not make change in soft device , is it possible Nordic help to give some instruction for how to implement it on app layer, as I believe our request is very useful for vendors based on nRF52840 to develop product and so have a request for BLE OTA testing(not based on DTM mode but BLE connection)

Thanks.
