BLE 4.2 Support in the BLE Mesh SDK

[Hardik V Patel]

 Hi,

We want that any bulb or any devices (Server device) of BLE 4.2 should be able to work with BLE Mesh SDK(Client). We are using the nrf52832 with SDK  BLE_2.0.1 for the mesh. My questions are as per below,

1)Is it possible to operate any BLE 4.2  device with this SDK?

2)Any Extra things required to work with BLE 4.2 like Proxy client or server?

3)If it is possible then Please provide us example code or document then to implement BLE 4.2 with SDK  BLE_2.0.1.

4) Is it possible to enable both the things BLE 5.0 mesh and BLE 4.2 in this same SDK?

Hi Bjørn Kvaale,

5) 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. 

1) Can you please 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.

5) I would recommend taking a look at & testing this dfu quick start guide. It will do a DFU of all of your devices over a serial UART connection to your computer.

1) Do you want these end devices to be connected in the mesh network or via a proxy node to a BLE connection?

Actually,

5) We Don't want to use Nordic traditional desktop tools like NRFutil or other. We want to do the firmware upgrade over the UART using the 32-bit microcontroller and it is RTOS don't have any OS, So please guide us how we can do this?

So Basically, We need two things to develop one is for the host(Ex:-32-bit microcontroller like STM32, LPC1788) and one is for the target(nrf52832 DFU UART). we need to develop code in the nrf52832 DFU UART and in the HOST controller(32-bit microcontroller) Serial firmware Update code over the UART.

1)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

We support Mesh DFU over nrfutil. I unfortunately cannot help you all too much if you do not want to use nrfutil or one of the other dfu tools we have available.
