Xbee Reset Pin 5 and Raspberry Pi

Sensors NFC & RFID

I have a client that would like to utilize a GPIO pin on his Raspberry to activate the reset feature on his Xbee module connected with a BOB-08276 board. We originally thought we could configure and pull the GPIO pin low to activate the feature, but he can’t get it working.

Is there any other hardware required between the RPI and the Xbee to make this work? Do we need to use the internal pullup resistors?

There is some reference to using a transistor to use this feature, but I cannot determine what the difference in functionality is between doing that method, and simply setting the GPIO pin to pull it low.

There is a diode on the chip for ESD protection, connecting RX to Vcc (anode to RX). When RX is powered and Vcc is open, this diode will power up the chip from RX, and therefore the LEDs as well.

You could also try pulling reset low and see if holding the processor in reset will reduce your power draw.

Pulling reset low should do the trick. Do you have a common ground between the XBee and Pi?
