Hi,
I am currently designing an Arduino compatible device that has both a Bluetooth module (for remote control) and an ordinary serial port (FTDI chip) for uploading code to the device.
I don't have my Bluetooth module yet - it's on its way - but I want to write some code in the meantime.
My question relates to whether the Bluetooth module and the FTDI will play nice if you connect them to the same serial pins of the ATMega chip / arduino. Does the Bluetooth module interfere in any way with uploading code via the FTDI chip? Is there anything I need to do to put the Bluetooth module 'to sleep' while the chip is being programmed?
Alternatively I could use software serial to communicate with the Bluetooth but this eats up some pins and is resource intensive.
Cheers.
