We have exiting BLE 4.0 device, which should be updated to the mesh. nRF52832
In the DFU for BLE4.0 you could update the booltoader and the softdevice with one update, with the next update you have to update your application.
If I run the update to the mesh-Booltoader and a new Softdevice, than I have the problem, the mesh booltoader has a restriction, that it can't run a dfu of his own, the booltoader needs an application, which wasn't transfered.
Is there a path for such an upgrade over the air? would you tell me please how to solve this problem?
