Blink on nodeMCU / RFM69 gateway

[rmh]

My gateway works fine with the vanilla wiring as per RFM69/95 & ESP8266 at https://www.mysensors.org/build/connect_radio and the example GatewayESP8266MQTTClient sketch.

I have tried adding the Radio Traffic LEDs as per https://www.mysensors.org/build/advanced_gateway but whichever available pins I use:
D2 / D3 / D4 : leds blink but comms to nodes seem to fail with NOACK
D9 / D10 : seems to work but lose serial output for debug.

I expect someone has made this work before - what am I doing wrong?

Thanks

In the default wiring, D1 is the only unused pin that is easy to work with.
D2 is used for CE so using it to blink a led as well will not work.
