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
