Official Launch VideoWelcome to this 2 or 3-part blog about the nRF52 Rocket, a BLE-enabled model rocket, which you’ve just seen soaring through the air in the video above. In the first part of blog, I will briefly introduce what model rocketry is and what are some of the motivations behind my work on a BLE-enabled model rocket during my fun and rewarding internship at Nordic Semiconductor.Model rocketry is a popular and exhilarating hobby that has inspired many young (or the young-at-heart) makers, hac...

Hi everyone. I've been having a bunch of trouble with the BLE examples being incredibly slow. However, I recently started encountering a problem where the flash file wouldn't compile, and by now it won't compile at all, so I can't use the boards at all currently.
