Note: I have ceased working on projects with the HM-10 and the CC2541. The difficulties of dealing with the IAR toolchain are too great. I now recommend ARM mbed solutions if you intend to pursue developing a BLE peripheral. I am leaving the resources I was able to gather online in case someone has use for them, but I cannot provide support.

BLE Dev Kit

Getting into low power Bluetooth peripheral prototyping can get expensive quickly. This project aims to chart out and the document the cheapest, easiest way to create a true, custom peripheral with its own profile. Head on over the wiki to read more.

Hardware

A sub ten dollar CC2541 development board based on the HM-10 module. This board is a fork of Ladvien's excellent work with the module.

Firmware

On-board application and profile examples.

Software

Client application examples (iOS).
