I've made a gateway from the RisingHF board set (RHF0M301 concentrator board). It is setup for 915MHz... I got it working initially with the RisingHF RaspberryPi image and their pktfwd executable, but now I've switched over to the ic880a howto, with the necessary tweeks for the RHF board.
I finally got the Adafruit 32u4 LoRa node to work... just now! The trick turned out to be careful placement of the Clock Error adjustment...
!!! You really have to put the LMICsetClockError(MAX_CLOCK_ERROR * 1 / 100); after the LMIC_Reset(); !!!_
Didn't Join at all until I did that after every reset... I will look into exactly where it is needed but it didn't work in the original place.
I had better luck coming out of sleep after I disabled all the Serial calls... I don't think the UART recovers properly or something.
I do see long stretches of missing data sometimes, even now...
Very relieved to see something end-to-end!
