New comer in the Sigfox ecosystem : the Wisol FM20R1.
Wisol have already changed the Sigfox module world by providing a solution based on the OnSemi design for transmitting on Sigfox network for about 2$. Now they are back with a full SoC solution for a really competitive price estimated under 15$. This solution is providing SigFox, GPS, Wifi, NFC, RF and includes an accelerometer.
As seen in a previous post, working with nRF52 and Eclipse is not the easiest challenge !
This post will detail how to create a template project for a BLE project using a softdevice working on the PCA10040 board and using my
This can be apply to most of ble starting project with nRF52. I assume you configured Eclipse IDE as described in
this post. As a pre-requisite you also need git. The tutorial works with SDK 12.3
nRF52382 is a BLE micro-controler based on a 32b Arm M4 core operating at 64MHz. It includes 512kb of flash memory and 64kb of RAM with a price about 2,80$.
It supports BLE (Bluetooth Smart) and ANT RF protocol. It also includes a NFC-A tag. NFC can wake up device and allow easy bluetooth pairing.
Device allows Over-the-Air Firmware Upgrade. It also have different SoftDevice (protocol stacks) with BLE or ANT8 or both.
By including internal Oscillators, power supply elements and Rf elements, this chip is a low cost solution for building IoT.
nRF52832 will be available Q1 2016 but development kit preview are available. (note – this post has been kept as a draft for a too long time !! )
Now, let’s read the next part for how to quick start with the development kit.
nrf51 ble stack
After building my first project using an nRF51 device from the template given in the SDK I was really disappointed by the result, I mean, it works but the code is really bad and hard to maintain.
The given examples are not really generic and if you have to create your custom ble service and characteristics you have to make many modification in a code that is not clean for all.
So my second project was to create a ble library to make creation of custom services & characteristics as easy as possible and to create a main file with less code.
