@skywatch @mfalkvidd Thank you for your comments. I am using Moteino R4 and RFM69 connected to hardware SPI pins. I tried the same pin with softSPI, but I could not get success. Now I have altered the ADE7763 Arduino library to update SPI settings on every call. And added code to update the only flag on ADE7763 interrupt(like we have in RFM69_new library). Seems all look somewhat ok. I think for RFM69 we use a default clock speed. for ADE7763: SPI_CLOCK_DIV4 Are you using pull up resistors on the CS lines to each device - that might be worth a try too.... Yes, I have

@gohan Indeed... See e.g. my experience here: https://forum.mysensors.org/topic/2890/chinese-rubbish-or-is-it

@jesse said: I found the solution on this page: http://mathertel.blogspot.com/2013/04/using-spi-bus-with-ethernet-sd-card-and.html The key is setting the Chip Select (CS) line to be different for each module. For the CC3000... "#define ADAFRUIT_CC3000_CS 7" Pin 7 is being used exclusively to select the Wifi module. https://learn.adafruit.com/adafruit-cc3000-wifi/cc3000-breakout For the NRF24L01+... "RF24 radio(9,10);" Pin 9 is being used for Chip Enable (CE) and Pin 10 is Chip Select (CS). http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo http://maniacbug.github.io/RF24/classRF24.html The other SPI pins: CLK, MISO, MOSI, are shared by the two modules and get wired in parallel. Hi do you still have a Gateway code when using CC3000 and arduino Mega or UNO(if it fits)?
