I am working with a Arduino NANO which includes the modulenFR24l01 in the same board (RF-NANO - picture attached).
The project includes store some data on a SD with time stamp so I got the DataLogger Shield which includes the SD slot and a RTC (picture attached).
The problem I did not see before purchase these two components is the fact that the RF-NANO includes the ChipSelect pin of the nRF24l01 on the same pin that the DataLogger Shield has connected the ChipSelect of SD (both are connected via SPI).
In order to avoid purchase a new Arduino Nano and a nRF24 module I tried to set communication module to PowerDown while I work with the SD (shield) but I dont have gotten any success.
The datasheet of the RF-NANO says that there is another pint called Chip Enable (CE) connected to PIN 9 on the Arduino but there are not too much information how to use it. I tried to put on "DISABLE" the nRF24 module via this pin but the communication with the SD module is not possible anyway.
Using the PowerDown function including the library RF24.h I got more or less the same "failure" (no communication with SD).
I have another idea but its includes cut the track on the PCB of the shield an connect the CHIPSELECT pin of the SD module to another pin on the same PCB.....but if I fail for some reason I will have to purchase a new Arduino AND shield.
Have you had this kind of issues or have any other idea how to overpass it?
In my country the price of the arduinos are not that cheap as other countries.
Thank you in advance for your cooments.
