Secure DFU using bluetooth

The PC tools we provide(nRFConnect, pc-ble-driver, etc) uses and builds on top of a connectivity firmware capable of decoding serialized SoftDevice commands and issue the corresponding call to the underlying BLE SoftDevice Firmware. So unfortunately, these tools will not be compatible with the any Intel of CSR dongles. Sorry for the inconvenience.

That sucks. Is there any way you could add support for WinUSB or similar, please?

You have to use either a nRF5x Development Kit or a nRF-Dongle in order to do DFU from the PC. Intel and CSR DFU is not supported.

Thank you for your reply, Sigurd!

nrfConnect does not detect any of my BT dongles - I have Intel and CSR.

After cloning that repo using git clone, I go to the dfu subdirectory and do 'npm install' I get some errors.

I then copy in the zip into that directory and do this: D:\pc-ble-driver-js\test>node dfu.js E4:46:5C:46:3D:12 nrf52832_xxaa.zip D:\pc-ble-driver-js\node_modules\bindings\bindings.js:96 throw err ^

Any idea on how to resolve this, please?

Hi,

For PC you can use nRF Connect to transfer the .zip packet. You can also use nrfutil, see this post. We provide Node.js interface to pc-ble-driver called pc-ble-driver-js. pc-ble-driver-js support DFU, see here for syntax.

node dfu.js FF:11:22:33:AA:BF ./dfu/dfu_test_app_hrm_s132.zip
