Implementing a Bluetooth Low Energy (BLE) device from scratch can be a daunting task. If you’re looking for an incredibly detailed walkthrough of developing a BLE project from essentially the ground up, you’ve now got a lot of reading to do: [Jocelyn Masserot] takes you through all the steps using the ARM-Cortex-M0-plus-BLE nRF51822 chip.
The blog does what blogs do: stacks up in reverse-chronological order. So it’s best that you roll on down to the first post at the bottom and start there. [Jocelyn] walks you through everything from setting up the ARM compiler toolchain through building up a linker script, blinking an LED, flashing the chip, and finally to advertising your device to your cell phone. It’s a lot of detail, but if you’re doing something like this yourself, you’re sure to appreciate it.
