New version of the Telecom design SDK has been released for TD1208 / TD1208R / TD1204 and now officially supporting TD1205.
This new version provide some bug fixes, like a crash after 21285 transmissions that could be after 212 days in case of full use… some I had in touch with could be interested… @pioupiou and also a bug that disable gpio interrupt after sigfox transmission (I experimented it !)
For the main evolution, this version is supporting FCC and TD1508 and improving sigfox transmissions.
From my experience, this version is also a good way to decrease the size of your binary files.
This post is about upgrading from a SDK 5 to SDK6 and the impact you can when recompiling your projects.
To install the SDK from scratch, just follow the well documented official post here.
The revolution slider is a way to animate a web page based on a wordpress plugin. When you create a slider it start to be animated directly when the page is loaded. So if your slider is on top of the page it is perfect but if your animation is on the middle / bottom, the animate will be finished when the user will scroll to that part.
I previously write this post on how to use a BeagleBoneBlack as a JTAG (SWD) programmer. It was fun but really slow. I port my code on RaspberryPI and now what was taken 5-8 hours is a couple of minutes.
To connect the SWD connector to the PI use the following schema
I use this peace of code to reflash my TD1204 and TD1208 based both on EFM32 when bricked after unsuccessful update…
When you plan to deploy / sell sigfox based solution to consumer, you have to manage you device park. The sigfox network have a restricted radio medium to ensure you will not emit more than what you payed for you will be charged by them if a device you own is emitting, even if it is emitting out of your control. There is no network subscription like in 3G before being able to emit so anyone can emit. That is why, to ensure every one is clear, you have an extra cost if you emit more than you are allowed or if you emit from a non registered device.
When you are designing end-user system you have no control on the device and if you propose a monthly fee to use your solution you will never sure the end user will unplug it once he stop to pay for your service. It means you could have a consumer stopping to pay for your service but a device continuing to emit and sigfox request you to pay for it.
Since the network allow you to have downlink message, now you have the capability to send order to your device and as a consequence allowing you to kill the device remotely. This is a good solution !
Next you have a new scenario where your end user finally decide to reuse your service and want to reactivate the device. At this step you won’t be able to communicate with it and you will have to find another way to reset its state to normal. You can eventually add a “factory reset” button or request to reflash it. There is another funny when : playing with the reboot time.
This post will describe how to lock a device to stop emit on network and how to play with the startup sequence to reset it. Read more !
After having update my Mac Os X, the java 6 have been removed and unfortunately Arduino request to use it. Personally I’m not really happy to install this not even more supported version of Java on my machine.
I was looking for the 1.5.8 Beta made for Java 7. I was not able to download it as the download stops in the middle even if I have a really good transfer rate at the beginning.
It seems that there is no mirror for Arduino (waouhou !! what that sh*t ?!?) and it seems this download problem is not really new. Here is the solution obtained from here. Use command line curl program:
After some discussions this afternoon with TD support and get a good advice from them, this post details some notice about TD_USER_Loop working way and power saving.
For those like experienced with Arduino, Telecom Design loop is not working like
But it is called on Interrupt ; I don’t know why but I was expecting it to be called every tick (32KHz) which was a wrong assumption. In fact, this procedure is called on wake up from any interrupt. The frequency of call can’t be determined, it can be not called in a minute if no events occurs. That is why schedulers helps you to have a predictable call.
