Hello,
We have nRF52833 on the custom board, now we want to do DFU over Bluetooth. During my initial research reults with following questions:
If you use
1. "nRF Connect for Desktop Bluetooth Low Energy"
Q: Why selected device allows ONLY Nordic dongles or DK. Why not standard PC or Laptop BLE Adapter not visible as "SELECT Device"? Any alternative?
2. nrf5SDK-Tool
I found that there is also a possible way to to DFU over BLE with nrfutil nrf5sdk-tools command. BUT Following written as description nrfutil nrf5sdk-tools dfu ble --help command says similar:
Perform a Device Firmware Update on a device with a bootloader that supports
BLE DFU. This requires a second nRF device, connected to this computer, with
connectivity firmware loaded. The connectivity device will perform the DFU
procedure onto the target device.
Q: The same issue, the BT device (as loaded or sender) must be nRF device.
So, finally: I couldn't find a sample or documentation about it. Could you please give more information or send docs link or videos "how to DFU OTA over non Nordic BLE
One more info: we whant to do DFU from Windows Application, that's why, C++ or C# library fits ideally if available.
Thanks
