I've been trying to get the nRF24L01 and the Wiznet Ethernet shield working on the same Arduino for a while now, but have not had much success. Specifically, I have a gateway Arduino w/ ethernet shield and nrf24L01. I'm trying to update Xively with a remote sensor node communicating with the gateway via nRF24L01.
I know you can't use both modules at the same time, and you need to set the select pin on the nRF24L01 such that it's different from the select pin of the Wiznet. But there must be something going on with the Xively module. I read somewhere I need to issue a stop command to the ethernet shield...not sure how to go about it.
It seems like such a common thing to want to do. Ethernet gateway with nRF24L01's acting as network to remote Arduino nodes, updating to Xively. But I haven't found any examples of other people doing it.
Any advice would be appreciated.
