All working now, thanks Chrille!! For anyone else trying to get RFM69W working with ESP8266 I have MISO -> GPIO12 MOSI -> GPIO13 SCK -> GPIO14 NSS - > GPIO16 DIO0 ->GPIO15 (Which is also pulled down with a 10k resistor) ANA -> antenna (to be honest i eyeballed 9cm but haven't measured it (was going to trim afterwards)) VCC -> 3.3V GND -> GND I also soldered a 4.7uf cap over the power and ground of the RFM69W directly on the RFM69W PCB For the power supply i have a 5V USB supply (old phone charger) with a 1000uf cap over the +ve and -ve. then and LD1117 to feed 3.3V to the ESP and the RFM69. Should probably also have 47uf cap somewhere on the 3.3V side as well. I saw people talking about them being too close as well. I tested most of mine about 50cm apart with no major issues. I made the following mods to get either the gateway or node sketch working #define MY_RF69_IRQ_PIN 15 #define MY_RF69_SPI_CS 16 All makes for a pretty cheap gateway. I was planning on using the ESP for nodes as well but is seems its power consumption is far greater than the arduino mini pro, so i ordered a few of them for nothing and will build my nodes based on those.
