Using Nokia 5510 and nRF8001 at the same time

[DJ]

I am using Blend Micro with Nokia 5510 LCD. Before applying BLE SDK for Arduino, LCD works fine. After initializing BLE UART for nRF8100, send text through nRF8100 by UART to IOS app is successful, but no LCD display.

How can I show the text on LCD and send the same text to IOS App through bluetooth by nRF8100?

It is so urgent~!!!

You are using SPI to connect 5510 display? As far as I remember, nRF8001 is also connected by SPI. I think you have to somehow modify the drivers, so they don't interfere with each other, or just find some arduino with more SPI instances.

Yes, SPI is used for both, but 5510 LCD is selected separated ChipSelect pin. Therefore, I think it has no interference. Do you have any example of modification of driver to use SPI for 2 or more devices?

I am not sure how busy is the SPI bus for each of these devices - you should analyze that first, so you can bbe sure they dont interfere.
