Hi!

Yes, this is possible. My colleague recently shared a sample demonstrating how to perform a DFU from one nRF52840 to another nRF52840. You can find it here: https://github.com/simon-iversen/ncs_samples/tree/master/central_smp_client_dfu

It's based on the central_smp_client sample.

Best regards,

Raoul

Thank you Jeremy,

I will test "ble_app_gatts" example.

The BLE DFU process is documented at https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v17.1.0%2Flib_dfu_transport_ble.html

Unfortunately there is no example that implements this, but there is a "ble_app_gatts" example that is a reasonable starting place to work out the GATT connection and characteristic discovery. I'm currently working on doing something similar, and it's not trivial, but it is possible.
