I am using Laird's bl654 dongle.
If you download a hex file using nrfConnect for Desktop, the dongle is no longer recognized. It works like open bootloader again only when the reset button is pressed.
I don't know why this is happening, as it is not shown anywhere in the datasheet, I cannot solve it.
Is there any way other than putting the code that makes it run as an open bootloader in the program?
There was no such problem when using nrf52840 dongle like pca10059. It was possible to use it as a usb bootloader after written the program, but I don't know why this problem occurs with laird's dongle.
