Hi Matthijs,
I tried to send a temp message to my radiator, but without success. Is your program able to send a message to a radiator, or is it just receiving messages?

Hi Matthihs,

>>> ... changing the packet length halfway a packet, but that's something we can simply try).
This works. I'm using it since many months.

Hi Matthijs, this is good News, that you figuerd out that the DataWhitening (DW) algos are different. Therefore we have to implement the DW according to the CC1101 in software. I set the Temp to 22.5C and get the following Raw-Data (C64DE3D07E63B4198125604D238D). Below you will also find the complet...

pls. look at the Appnote from silabs AN592 and the Design Note DN509 from TI. These notes are describing the hw based data whitening algorithm. hope this helps. pls. inform me, if you find a way that the CC1xxx and the RFM22B can talk to each other.

Hi Matthijs,
no I couldn't move any step forward. I've contacted silabs support, but still no progress. They mentioned that the hw based data whitening algorithm is not compatible to eachother. I've checked it and couldn't see any difference. So I'm stucked.

Hi, I've gone over the forums, but still have now idea what this string means: 2912A0051221006028033320019001A004058000010000A0864008403011224036005252204024030080 I have received it over wireless It was the reaction, after I set a temperature (21Deg) on my iPhone. Zhe cube has communicated with the...

Hi,

now I have it working with RF22B module.

I get this data every 3-5 minutes from my MAX!. What is that?

I already tried to interpret the reg settings, which are posted in that thread, but in the datasheet there are formulas which are referring to the osciallator frequency. But I don't know the schematic of the cul. It's getting very difficult to find out the needed info.

Thanks,
SF

Thanks,
But I cant find the requested Info like cps, frequency...

Hi, I have developed a piggy-back board for the raspberry pi (rpi) with the RF22B transceiver module. Since some weeks, my wMBUS software stack is up and running. pls see the following entry @ rpi forum: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=45&t=20432 My next plan is a sw module whi...

Has anyone a description about the Radio Signals at 868.3MHz.
I want to get rid of the max! cube itself.
ELV offers an USB Stick, which can communicate directly with the devices. Maybe this stick can be used for the max! devices.

Is the Protocol KNX or M-BUS compatible?

Thanx,
SF

Can anyone post a detailed description and correct examples about the S Command pls.
