i have Arduino nano with bluetooth hc-05 as one board and one SD-Datalogger. I want to send data from SD-Card to Android/computer via Bluetooth. Everything works seperately(Arduino-bluetooth) and (Arduino-Datalogger) when i combine all, i got no results.
SPI-pins: 10-11-12-14 (ss-Miso-Mosi-Sck) Pins 11 and 12 are automatically reserved for the bluetooth modul and i can not change it. Sd-Card needs also Miso/Mosi(Pins(11/12)). The Problem ist that the bluetooth modul doesn't have a ss to disable it when using the sd-card.
Any help? Or may be can i define other digital Pins as Mosi/Miso, add another SPI pins, i dont know what i have to do..
