Although this is easily fixable, Nordic engineers should be made aware that they made a minor change in SDKV12 that breaks makefiles on the Mac.
In /components/toolchain...
Hi,
I have downloaded the latest SDK12 for nRF52.
And i tried out the new "BLE Secure DFU Bootloader" example.
But i found that doing the BLE DFU with nrfutil on...

There are certain design decisions that break C++, or at least the separation of concern between allocation of entities and the use of entities.
For example:
typedef...
Hi there,
Is there any chance future SDKs with the nrf52 have support for Mifare Classic cards? The example with the Adafruit shows an Ultralight tag, but it would be useful...
