configure xbee without adapter

Hi all, was wondering if there is a way to configure xbee modules without a usb/ftdi adapter. Here in greece they cost about 20-25euro :fearful: and buying one from ebay will make about 20 days to come. So :smiley:

my setup:
i got an arduino mega 2650
2 xbee series 2 modules (2mw)
a mega sensor shield v2.3 from dfrobot that can hold up to three modules

i tried to discover the modules in xctu without success, obviously :P.
i also tried to put the arduino in reset mode (by shorting reset and gnd). still cannot discover the modules.
i also tried to reset the modules (short pin 5 and 8 from datasheets).
in xctu i set : 9600 baud, 8 data bits, parity none, stop bits 1, flow control none/hardware. here i must state that xctu can see the mega on com 7. so i think my mega is ok. plus the green led under each module on the shield is constantly green.

any ideas? ty in advance.

It is. All you need to do is remove the AtMega chip from the Arduino and then mount the XBee shield.

Unless you are real good with a soldering iron, buy the adapter.

eh i dont wanna brick my brand new genuine mega :roll_eyes:. what about the "reset" method?
any other ideas? :~

Load empty sketch into Arduino. Then connect Xbee to pin 0 and 1 and try XCTU. You should try all the baud rates, or is your Xbee brand new? Hw reset will reset it to values saved in NV memory, so there could be written different baud as 9600.

yes both modules are brand new. im gonna try all the baud rates as you said and post feedback. ty

edit. i finally made it to program the modules by using an arduino uno without the atmega. now everything works fine :slight_smile:
