I have a product that use a FTDI chip on a AVR uart
and at the other end can we connect a PC for calibration etc.

Now the question is are there an easy way to use a smartphone to do the job bluetooth or ? one end has to connect to the USB connector.
It's only for service so price is not a big problem.

Something like this perhaps?

Most articles about Android and AVR seem to mention HC-05 or HC-06:

No I can't get to the UART, only the USB connector.
I will have to have a USB to RS232 module then.

I guess that two FTDI chips connected on the USB side don't work, one will need to be a host
or am I wrong?

The Basic4Android compiler has a USB lib that interfaces as host with FTDI. I do not have direct experience. I use BT, with BT module on AVR side, and like that.

It all starts with a mental vision.

You could just use an FTDI VNC2 chip in host mode and a BT module.

FTDI has some sample code/projects that would hopefully simplify development a bit.

Alternately, most current android phones and tablets (with a USB OTG connector)will talk to an FT232 chip directly. You could test first with some of the free android terminal programs and a cable.
The tablet / phone might balk at supplying too much current to the target. It depends on how you have the FT232 EEPROM programmed (or just use a powered USB hub inline).
