Use Segger JLink USB drive as means to configure my device through a configuration file

[dragilla]

Hi,

When I plug in my NRF51 Dongle it shows up in Windows explorer as additional drive (JLINK). Can I use this medium to configure my application? Can I read a file pun on this drive in my application running on my NRF51 Dongle? I would just put a simple config file and then read the parameters inside the app.

Thanks

Hi,

What will your device be made of in the end? the nRF51 dongle has an onboard debugger, but I assume you will not have that in your end product? If so, there is no USB. If you need USB, then you should look at for instance the nRF52840. If you want to do this configuration ni production with a debugger attached (same as you have on the nRF51 dongle), then there are a few options: Use UART to transfer data, program a hex that contains your configuration. Finding a way to access the data on the Segger interface IC may be possible but I am not sure, and I have no idea how. If you really want to go down that path I suggest you contact Segger directly.

Thanks. I don't know how the producct will look like. It depends which way I go. For now I'm trying to keep things simple. It looks I'm going to go with UART for now. I will write an APP for Windows that will connect to my device through UART.

The next step, I think, will be to use 310 softdevice and write an Android app that would use Bluetooth to connect to my device. But I'm not good enough to do it now, and don't have enough time to spare :)
