ESP8266 Gateway and RFM69HW range
-
In my testing of a ESP8266 and a RFM69HW radio at 915MHZ, I noticed that I no longer had any range, 100 ft max. Using the same radio on a serial gateway, my range was over 1000ft.. I suspect that the WiFi radio was desensitizing the RFM69 radio receiver... So be cautious! and do some testing.

I think so too... rfm69HW has a big tx consumption, combined with esp, it could be a power problem. esp and rfm are really not on the same frequency so I don't think they could interfere each other but maybe I'm wrong...

The radio do not have a tuned front end, that why I think it a desensitizing issue... Both radio have 100uf chip cap across 3.3V and gnd... Gateway was connect to a large lab supply, remote is running from a 7ahr lead acid battery with a regulator to 5v with a 470uf cap to the VIN on a Moteino board, radio again has a 100uf cap on 3.3v.
Radio on ESP8266 gateway and serial gateway are then same exact radio.
