Title: Getting off the ground basic question
Post by: malachib on April 09, 2018, 02:21:33 PM
I have an experimental setup with:

Node A: Adafruit ESP32 Feather + RFM69 FeatherWing
Node B: Adafruit M0 + RFM69 Feather

Utilizing the 'random temperature sender' example, I am unable to get the two to communicate.  Probably something basic, but it's eluding me for hours now. 

I put in a 'readRSSI' call for some extra confidence that SPI communication is happening, and I do get sensible values back (-99 to -106) - but only if I issue a send.  Send always returns with a 'nothing...' and as you probably inferred, I never witness a receive.  Where do you think I should look next?  Thanks in advance

Things to know: I put in explicit reset code, both are 900Mhz, and I did remember to solder a 3-inch antannae on :)

Maybe someone can answer but you may be better off asking in the adafruit forum where they speak feather language ;)
