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.
