Degugging embedded software is not easy. There is no terminal to display what is going on. Engineers need to implement smart mechanisms to visualise the flow of their code and spot errors without impacting the performance and functionality of the original software. The simplest techniques used in embedded debugging are blinking LEDs and UART loggin…

In this post we will share a detailed description of how to program and debug the BLE Nano using an open toolchain based on eclipse and GNU gcc. These notes are based on Nordic’s tutorial Development with GCC and Eclipse. This is a long…

We will also show how to upgrade the firmware of the module to a new version. Enjoy! Configuration of HM-10 as a Central Device The factory firmware of the H…
Read MoreHM-10 is a Bluetooth Low Energy (BLE) module built on Texas Instruments CC2540 o CC2541. Chinese manufacturer Jinan Huamao Technology is the developer of the board and the firmware, although there are several clones available in the market as described in the original documentation. The module can also be purchased already mounted on a brea…
