How to save and read a raw data in PC?

[Rui Tan]

I am working on nrf52840 and also the dongle by segger. My data is transmitted via BLE sucessfully but I can only see the results in figure but I can't save and process the raw data.

So I want to use maybe USB to send the raw data to my PC. Is it possible? Can I have a example of the coding? Do I need anymore software in PC to read it?

It is also good if I can save the data somewhere else(like in SD card ot a way to save and read out in DK itself if possible), I just need to record and process this data.

Happy new year all!

Hi,

Here is the usbd_ble_uart example but modified so it acts as a central instead of peripheral. You can store the data by using the fstorage module.

Hi Jared,

Thanks for your reply!
I checked already the usbd_ble_uart example, but i found inside "read me", it seems this example is only avalable for PCA10040 but not PCA10056. Is it an issue?

Best Regards,
