But what if you want to use another make application?

I am working on a system the include communication from a smartphone to a controller.
The controller support RS232, the smartphone support Bluetooth and to bridge this gap I purchased a ‘Bluetooth Serial adaptor’ from ‘LM Technologies’.

The connection works well until the device sends a string longer than 20-40 characters. Then the LM058 freezes and never recovers. (power cycle require)

I tried all known configurations, I sent question to LM support (there website support is terrible), I posted a question in related forums (and in an unrelated forums .

At this stage it become apparent that either my device is faulty or just badly designed.

A week after my initial question to LM support I got response that suggested disabling the ‘escape character check’ using the AT command ‘ATX0‘. That indeed solve the problem.

BUT!!!
Why is this feature not documented in the LM058 user manual?? or any other related LM058 documents!!??

In the purpose of this blog I am adding a link to another adaptor manual that actually describe this feature. It seems that LM updated the LM058 adaptor functionality but not the manuals.

here it is: a little piece of information that was not part of the ‘world accumulated knowledge base’ (Internet) and now it is.
In the future I’ll try to be more informative and ‘to the point’ and less ‘blah blah’.

Anyway I was looking for a while for how to print debug messages in the JDE’s debug window and now I found it.
Simply use the system output stream:
System.out.println( "message " + number );

But if you actually need to convert odds as part of a script here is how to do so:

There are three types of odds format:

• Fractional: 9/5 for every 5 dollars you invest you get 9 if you win and the original 5 stake.
• Decimal: 2.8 for every dollar you invest you get 2.8 dollars, that include the original stake.
• American: American odds are divided to two parts positives and negatives.
  Positive: 180 for every $100 you invest you win $180 and get your $100 stake back.
  Negative: -180 to win $100 you need to invest $180, so if you invest $180 and win you get $100 and the $180 stake back.

Conversion between odds is rather simple.

Given the fractional odds numerator/denominator ( for short: num/den)
The decimal odds are computed as decOdds = ((num+den)/den)
The American odds are computed as follow
if (num/den > 1 )
    usOdds = ((num/den)*100)
else
    usOdds = ((den/num)*(-100))

At first I use the class connector interface to open a serial port, as they use in their samples. but I couldn’t get it to accept messages coming over the port, I spent hours on that, tweaking the port and the code, nothing. The DataInputStream.available() always return zero, although I know it got a response. Eventually I found a different class, oddly enough named Class SerialPort that worked perfectly well. RIM did advised not to use it, but I am not going to use it for the final product anyway.

Eventually I decided to open a blog in my own site, simple and straight forward. My hosting provider have wordpress ready to install, click clack and it’s running.

Now I had to add a bit of personal touch, so I downloaded a theme that suits me, tweaked it a bit and here you go.

My name is Raz and I am a software engineer for 10 years now. As an engineer I am having challenges on daily basis, most are simple, easy and resolved by employing my knowledge and experience, Some are more difficult and require investigation, usually googling the problem and find the solution in over the web, and the last are challenges that it seems I’m the first to encounter or, to be more modest, no one ever post the solution on the web.

In general, I believe that sharing the knowledge on the web is important and so I decided to describe the third type challenges and solutions in my own blog, for others to enjoy.

This blog is not about me, it not going to be personal or interesting, just a list of facts and experiences that others can find and use in there challenges.
