Send me a private message & I can put you in contact with your local Regional Sales Manager.

2)We required both as we are going to support both the things but currently we don't have any devices so if you have any contact then for any of them then it would be great

1) I would take a look at this link. It will update the all of the devices in your mesh network over serial uart. If I were you, I would not suggest doing your own UART DFU. Just my honest advice. I think this would be quite difficult to implement.

2) Do you want the end device (e.g. bulb, light, door, motion sensor) to be part of your mesh network or connected via a proxy node to BLE?

Hi Bjørn Kvaale,

1) As you mentioned you are not much sure how much easy to implement own UART DFU so Can you please give us contact detail who is expert in it. As we want to implement our own DFU, so we need the proper guidance with documentation.

also, It would be great if you could suggest any vendor who is working on Nordic BLE 4.2 or BLE 5.0 for manufacturing end devices like Bulb or light, door and motion sensor. We required this three device to work with our product which is based on the nrf52832 with SDK BLE_2.0.1 for the mesh.

1) It might be possible, but I am not sure it will be so easy to accomplish. The mesh sdk can either do side-by-side or bootloader DFU (see link). Do you want to be able to update a single node in the mesh network over regular dfu, while still being able to participate in the mesh network after the dfu?

2) There is a lot of documentation regarding DFU. There is the link above & a lot of documentation in sdk 15. Also, devzone has quite a few resources and cases regarding DFU.

3) Take a look at the infocenter links I posted. This link should also be helpful.
