MQTT on TC65i implementation

[Nikita Kapitonov]

Hello everyone!

I've successfully run MQTT broker on my server, and have many MQTT non-tc65i clients.

Now it's time to add MQTT capability to our TC65i devices.

Does anybody have any experience implementing it on our platform?

Googled it, seems there's no easy way...

Hello,

there was thread on stackoverflow, where it was said that it should be fairly straightforward to port paho client for MQTT:
http://stackoverflow.com/questions/10224256/mqtt-client-for-j2me

but you probably already saw that by yourself.

Reagrds,

Jure

Yes, I saw it.

Actually I cannot manage to compile it, and also it's quite big.

So I'm looking for real experience.

Hello,

I think, that cannot be a problem. I implemented simple MQTT client for my M2MScript (EHS5 and TC65ix javascript) succesfully.

MQTT protocol is simple.

Hello Ondrej!

Thank you for your experience!

Yes, MQTT protocol is not that hard, but I hate doing it from scratch.

We did find port for our STM32 devices, though it required some work to make it run.

Browser javascript client also runs perfectly.

I hope maybe somebody did that work on Cinterion chips.

[Ondřej Janovský]

I will do it soon, but now I have big problems with C and PIC chips.

Hi Nikita,

I have a MQTT client which was designed for TC65i but I haven't tested it yet. So, you will find it attached. If you test it, let us know your results!

Regards,

Thank you Ahmed, I've already ported MeQanTT, but I'll look into your code also

In case somebody interested, now I use port of MeQanTT, as it is quite small and has everything I need now.

Ahmed's file is a paho mqttv3 port, it is quite large - 345 kb vs 50 kb meqantt, so I didn't test it.

MeQanTT port is in attach
