I had posted some questions about this project earlier this week. Arduino uno + w5100 ethernet shield + nrf24l01 transeiver.
The w5100 is running a webserver to accept GET requests and parse out the variables - Works all the time
The nrf24l01 is acting as a transmitter and sending data out to other nodes - Only works with no Ethernet code.
What doesn't work is both at the same time. With everything hooked up it parses get fine, gets the variable but I can't transmit it since the radio never seems to fire up. Remove all the ethernet code and leave just the radio code it sends fine.
Code here. http://pastebin.com/SMWC9x4F it errors at 146. Which I assume is the radio never starting since the:
I'm using manicbug's library.
I use the EXACT same send bits in that file to test wireless communication, it works. I only need it to transmit wirelessly when it get data from the network.
CSN -> 10 CE -> 9 MISO -> 12 MOSI -> 11 SCK -> 13 VCC -> Separate 3.3 source, not the arduino GND -> GND
My guess is this is because both are using SPI.
Tried the softspi method http://pastebin.com/4mv612B7 .
Same thing. I can post GET to it, parse out variables but nothing on the radio side. And I still get no output from radio.printDetails() so it just must not be starting. Commence hair pulling..
EDIT: Bloody hell, printDetails() relies on printf...... that would have been handy to figure out an hour or two ago. I can get details now. still having communication issues. Will post more debugging information in a bit.
