Where can I find out about these alternate methods? ESP8266 BASIC only has the one type (at least that is documented) and I didn't see this in any of the NODEMCU/LUA documentation. I had to do a custom build of the NODEMCU firmware to get the SPI module. I can now create the messages I want, I just need to figure out how to send them in a background loop that doesn't interfere with the WIFi transfers.
