Re: [paho-dev] Problems compiling org.eclipse.paho.jmeclient.mqttv3
Hi Ian,

I’ll give it a try to compile the low-level embedded C client for the Spark Core. And looking forward seeing the high(er)-level C++ embedded API one of the next days (that I’ll also try with the Spark Core).

Thanks.
Guy

Hi Guy,

we've not had any problems with the low-level embedded C client in any environment we've tried it so far. 

Oh - there was one instance of a really old C compiler for a PIC chip which had memory model options for static strings and the serialize connect call uses a couple of them, so the code had to be modified a little.  Apart from that, no problem.

This level of API (which I'm now calling MQTTPacket) is really low-level so it does need more work to use it in a program, but there are examples in the repo.

We are working on a higher-level C++ embedded API, in MQTTClient.h, which works very well in the mbed and Arduino environments, and is more natural for them.  As the Spark Core is advertised as Arduino compatible, then this could be a good option.   I hope to have this library with Arduino code in Paho in the next couple of days, and add it to the Arduino community too.

Hi Ian,

Thanks for the effort. Well in fact I tried to compile it against the 1) J2ME 3.4 and 2) the adapted Java SDK of the Gemalto Cinterion Concept board. But both give problems. If you have any suggestions i’m more than happy to try further to get the library working.

Other option where I’m also looking for is to use the embedded C library with:
  • TI CC3200 MCU (I know there’s a webcast of it given by Benjamin CabĂ©); he uses the library from Code Composer Studio, can it also (out-of-the-box) be used from Energia (energia.nu)?
  • Spark Core (www.spark.io)
Thanks.

Hi Guy,

I presume you are using the 3.4 Java ME SDK?  We have been finding it difficult to find someone to answer your question, but are going to try to get the person at IBM who did some work on the ME client in the past to look at how it builds with 3.4.

We are uncertain as to the level of interest in Java ME, and how much effort should be put into it.  Are there other options (like a C/C++ library for instance) for your application? 

If there is anyone out there who would like to maintain or contribute a Java ME MQTT client, we would be very interested to hear from you!

Hi,

 

I’m trying to build (using ant with the provided build.xml) “out-of-the-box” org.eclipse.paho.jmeclient.mqttv3 (source); however I get a lot of errors (see below). Please can someone give me some hints to build successfully the j2me client? Thanks.
