    146: The Loyal Opposition

    Philip Freidin, founder of Fliptronics, discusses his open-source hardware platform OSHChip, a 16-pin DIP package containing a Nordic Semiconductor nRF51822 SoC designed to make Bluetooth Low Energy (BLE) development accessible to hobbyists. He explains the engineering challenges of creating breadboard-compatible pins and details the companion CMSIS-DAP debugger, which allows drag-and-drop programming and debugging via Keil, mbed, and GCC toolchains. Freidin also shares his transition from 20 years of high-stakes consulting to selling products on Tindie, highlighting how Hackaday's promotion drove initial sales and how professional developers now use the platform for rapid prototyping.

    345: Do What Apple Says

    Gretchen Walker, a mobile software engineer at PunchThrough, explains how to build iOS apps for Bluetooth Low Energy (BLE) devices using Apple's CoreBluetooth framework. She details the necessity of using Swift, the challenges of Apple's strict App Store review process, and the opaque nature of iOS pairing and bonding mechanisms. Walker also discusses debugging tools like Xcode and TestFlight, and advises against cross-platform development due to significant differences between iOS and Android BLE implementations.
