Lots of helpful people here so I'm hoping this is the right place for this question.
My goal is to take incoming UDP data and push it out the HSPI.

I have tried doing this with NodeMCU but I am running into. First I can't reach the throughput I need (just under 1MB/S, hence UDP instead of TCP) and it also seems like I don't have enough control with NodeMCU to just receive a byte and push it out to SPI. It seems the n("receive", ...) function is waiting for /n.

I'm hoping I can achieve this in C perhaps but I'm open to all suggestions.
Thanks in advance!

I am looking at something similar, wondering what the maximum streaming throughput the ESP8266-12F is capable of.
I am looking at streaming 8 channels of audio 24bit x 48kHz which raw data is about 12Mbps, or with NRZI encoding, about 6Mbps.
The only option is to use the SPI or HSPI, and I want to send A/D from one ESP8266 to another ESP8266 D/A.
I suppose it could be seen as a wireless 7.1 audio project, and I am hoping the ESP8266 is capable of moving this data rate, from what I read the bottleneck is the pin I/O, and I can't find any info on what the maximum data rate end to end is.
Or maybe there is something better suited than the ESP8266? Maybe the pending ESP32..
