Hi Z,I'm gathering together some bits as the data is apparantly sent over 433.92MHz AM radio by OOK (On-Off-Keying) and there is some info on the 'tinterweb about the protocols used.I may just get another weather station with serial out on the receiving consol and do it that way.I also have a Raspberry Pi on order (for ages now), maybe a low power web server and automatic weather station??!!Too many projects and not enough time...!Nigel.
In regards to the RFM22B I've talked to someone that is trying to get some as well and the only ones he could find available were the RFM22B-868-D, will those work? Does it need to be the 433 model or it's possible to change the frequency.
Okay one thing iv noticed between the different in graph that you postted and the one i posted yours seems to be a lot cleaner and not as jagged spiked like mine . but that said mine is set to max output. once i get my board from you i would like to use it to test home made 433 radios . what would be the best set of settings for use with RF probes and not antennas? i would image i would set the Tx/Rx power right down to minimum ?
As I got the order stuck there, I was wondering about this: http://rf-store.com/index.php?view=2&pv=showart&prod_id=RFM70-SIf I can build the same frequency scanner with it as well for 2.4Ghz. From the specs it seems so as the frequency can be selected up toa 1Mhz interval.
It's register 05 for the RSSI.Btw, after almost a month I got an email saying that my RFM22 were shipped...I had asked to include one of these cheap 2.4Ghz... but got no reply. :SWe'll I'm going to start assembling the boards as yesterday I got the solder paste and I expect the RFM's to arrive during next week.
That's a long time to wait! I have been flying my plane with the RFM22, it's working great so far.Register 05 is write-only, it's "RSSI Threshold for CD detect". You can't read the RSSI value from it.
