How to avoid error Update Firmware on XBee s2 via X CTU

XBee & XBee Gateway XCTU

I have 2 Xbee S2 Modules (ZigBee Router AT) (https://www.sparkfun.com/products/10414) that are set as “Router AT” with firmware verison 228C.

I have 2 Explorer Boards (USB) and i am using the XCTU software to help me update the radio module firmware. However when i select “coordinator AT” it will give me 7 firmware versions: 20A7 (Newest), 20A0, 208C, 2070, 2064,2041,2021. Which one do i choose?

My explorer board is from Adafruit. https://www.adafruit.com/images/1200x900/247-01.jpg

Once i update the radio module via XCTU 4/5 are [OK] but the last check says [ERROR].

The correct firmware versions would be 20A7. But you need a board that has DTR and RTS connected thru in order to change firmware. I would suggest checking with Spark Fun to see if your version of their board has these lines connected thru.

The one i purchased from adafruit has “DTRn” and RTSn" would that make any difference?

For writing the firmware yes. For encrypting the file no. What you are going to need to do is to delete the file XB24-ZB20A7.ebl from the C:\program files x86\Digi\XCTU\update\ebl folder and the XBeeS2 folder from the update folder. Then download the firmware files again.
