## Summary

Hosts Elecia White and Christopher White discuss listener emails covering Bluetooth 4.2 security, the definition of masked ROM, and the use of the volatile keyword in C. They review Elecia's work on precision mice feeders and bike lights, and detail their disassembly of BB-8 robots for competitive analysis of their BLE and inertial sensors. The episode concludes with commentary on Amazon's work culture and drone regulations.
