TC65

Moved to github This has been moved to github. Still as a backup: Motivations Transmit and receive in real-time Transmit as few data as possible Send and receive any kind of data Basics So the basic ideas are to : Keep a TCP connection open all the time by sending regular keep-alive frames. Define named channels that are only transmitted once (to reduce data consumption) Send byte array, and two-dimensionnal byte arrays on these channels We rely on the TCP protocol for packet checksuming, packet ordering and every little things it does very well We send these kind of frames : ...

Someone recently asked me and the javacint group how we should handle settings. So I’ll give you two answers : ejw’s reply : You should use some simple DataInputStream and DataOutputStream objects. Mine : If you only store simple values (numbers and text), you should use a simple text file. It enables you to easily see and modify settings outside the TC65. So, my little gift of today will be a simple settings management class. The idea is that this file is in a very simple format (that can be read in any PC) and it only stores settings that have changed. This is very important, it allows you to change the default behavior at next software update but also enable you to override some of the settings for each chip (like the last IMSI identifier of the SIM card). ...

Hi my dear visitors, Some of you seem to like (or fall by mistake in) my unfunny, unspiritual and crappy english speaking blog. I’m very glad you have such bad taste. You are more than 2 500 to come each month. You mostly come about some stuffs around the TC65, SVN, C# .Net or Sharepoint. By the way, you consumed more than 200 GB of bandwidth this month, mostly on downloading the TC65 SDK. I’m really surprised, I guess a lot of people use this chip even if nearly nobody writes about it. ...

This is just a quick code to show how to do a simple http POST request from a TC65 chip.

I made this simple test website for those of you who would want to check if their HTTP request made from a simple equipment like the TC65 are sent correctly. The idea is simple : You choose an id like “ThisIsMe” You access the test website with this id : http://test.webingenia.com/ThisIsMe You check what was the content of the request at this address : http://test.webingenia.com/read/ThisIsMe You can contact me if you don’t understand something, if something doesn’t work or if you would like me to add a feature. ...

I’ve been working on a project where we had to use Flex on a .Net environment and it had to be realtime. I was a little worried at first that it could be tricky to set up. But with WebORB.Net it’s pretty easy. We used the integrated RTMP (Real Time Messaging Protocol) messaging server. It’s almost like using WCF. The most important differences are that, by default, objects are transmitted as Hashtable and calls can’t be synchronous. We can bind the object to right .Net object within the WebOrb management console but we decided to do it ourself using reflection (because we don’t like to depend too much on the management console). ...

Update (2011-06-28): You should look at the jOBEXFtp program if you don’t want to spend hours fixing a problem with a crappy software. When you want to locally deploy software on your TC65 chip, you need the Module Exchange Suite (MES). If it doesn’t work, it won’t tell you why, finding out why can be quite tricky. ...

I have just made a little update to the SMSOTAP program so that the little message generation wizzard can add the NETUSER and NETPWD parameters in the OTAP SM sent to the TC65. Thank you John for this little feature request. This pretty useful, without it you could end up adding a new SM and editing each message. ...

I made some few changes to the SMSOTAP program for the TC65 : I removed the time limit, it’s stable enough to do not force you to update it frequently. It now uses class 1, PID 7d messages instead of class 0, PID 00 compatibility mode (it doesn’t change anything). It generates OTAP SMS only with the parameters you specifiy and use as few SMS as possible. Most of the time, you can use only one OTAP SMS It will prevent you from sending SMS above 140 chars in 8 bits and 160 chars in 7 bits. I fixed a little bug, I replaced “APORNUM:” by “APNORNUM:” Configuration file from the previous v1.1 version will still work on this one. ...

The program crashes with this error : ^EXIT 00010000,02d6414253485f4c434c2c70726f6365647572655265636f72645f702d3e6e756d6265724f66526567697374657265645461736b73203c3d204d41585f4e4f5f524547495354455245445f5441534b53 ^SHUTDOWN If you convert the hex array to some text, that will give you : ...
