Hello,
Has anyone out there successfully been developing on MacOS with gcc? (something we really like about Nordic) I was able to build the blink_led example from the swra446 example without using Eclipse, really simply on the command line.
But, was unsuccessful loading it into a stripped-down SensorTag using a Segger J-link.

We have a pretty simple, high volume design, and it seems overkill to use the IAR or CC tools.
We do want to send an iBeacon eventually though. Think it’s reasonable to link in the BLE stack necessary to do this using the gcc tools? No debugging, etc, needed.
Thanks!
