Programming a nRF51822 BT SMART BEACON KIT using hci_dfu_send_hex

[Dag Magne]

Hi.

I am new to this forum, and can be described as a programmer with very little embedded experience.

I have bought a nRF51822 BT SMART BEACON KIT, and are trying to figure out if it is possible to reprogram this devise using a PC with BT4.0 USB dongle and the "hci_dfu_send_hex.exe" program, or do I need additional HW to do this?

I see the nRF51822 in the Blutooth Add Device dialog on my PC, either as a "Beacon Config" device or as a "DfuTarg", depending on which button on the device I press...

But in order to program the device using DFU and the hci_dfu_send_hex.exe program, I seem to need a COM port, and none of the above mentioned devices discovered seem to have a COM service...

Maybe I have misunderstood completely how programming of this device can be achieved, but any help is appreciated :-)

Hi Dag

I recommend for you to look at the user guide for the Beacon kit if you have not already, available here.

For further information on how to program the Beacon kit, look at this thread.

Hi Stefan, and thank you for the tread link. I think I found the answer to my question in this thread; In order to program the device with a new application, I must upload the .hex file to an android/apple device, and use the Rf Tolbox App to program the device. I.e. Over-The-Air (OTA) Device Firmware Upgrade (DFU) cannot be done using a PC, but can be done using the Rf Toolbox App running on a mobile phone/tablet.
