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.
This year M2M and IoT are two of the most heard keywords in our technological domain. One of these is fresh new, I mean a couple of year old, when the other one is pretty much older. M2M, standing for Machine to Machine is a capability for two machines (or more) to discuss together and take actions. Like a temperature sensor allowing your boiler to decide when to start or stop. In the industry where automatism are in place since many year, M2M is something in place, running, not new. IoT, standing for Internet of Things is part of the M2M technology but actually raising. In IoT the main word is Internet and it stands for the capability of an object to talk over Internet on its own. Why only now ? mostly because now it starts to be possible.
I was looking for a system able to work with an iPhone (Bluetooth Low Emission – LBE) and a standard android (Standard bluetooth / rfcom). The RFDuino Arduino platform I have is perfect for BLE so, I decided to add a HC-05 module for the standard bluetooth.
The RfDuino arduino device i’m actually hacking is a bluetooth 4 (BLE) device. I was expecting to work with it as any bluetooth devices in a terminal session like with rfcomm in previous version of bluetooth.
In fact not ! BLE are not pairable as the classical BT device, they are discovered by the application itself. Then you have communication channel you can read or write to communicate.
Thanks to a post in a forum, I’ve found a really usefull tool lightblue allowing to connect any BLE device and send it data. This soft works on iOS and MacOsX.
