Hi,
I bought the nRF52840 in april. The problem is that my iPad doesn't detect the nRF52840. Also, when Itry to upload a .hex file on it, the board tells me that the upload failed.
I am a beginner so I don't really know if the it's the firmware problem or something. I don't know how to upload a firmware on the board.
Can you please help me solve problem?
Thanks
