I've spent a great deal of time researching how to resolve this issue and have come up short and would greatly appreciate any feedback you may have.
Each time, I try to update the firmware on my Xbee Series 1 radios, I get a pop up message "ACTION REQUIRED! Reset your radio module" and the update fails.
Here is the sequence:
Getting Device Information [OK]
Entering Programming Mode [Error]
Could not enter programming mode> Could not reset the module.
Error updating the radio firmware.
It can read the radios just fine and I can update settings on the radios just fine, but it will not apply the firmware update.
I've installed the FTDI Drivers on Windows 10 and have tested this (same results) on my two different computers using two different versions of xctu and 2 different radio connection types (ftdi cable from adafruit and the arduino board trick). I have 3 different xbee Series 1 radios, 2 I ordered about a year ago and 1 that I ordered a few weeks ago. All 3 produce the exact same result. I am completely baffled.
The process reads the radio with no problem. I have the communication set at 9600,8,N,1,N and have tried both AT and API mode on the radios.
I have installed the FTDI drivers on both computers (once previously on Win 7 computer and once with a fresh XCTU install on Windows 10.
My radios are all marked with XB24-AWI and 2 (older ones) are 001-REVE and the new one is 001-REVH.
I am using the adafruit xbee adapter (P126). I had the two older radios working just fine, but decided that I should update the firmware to the latest version (10EC to 10EF).
I did try resetting the radio (pulling and reinstalling the radio, and setting reset pin to ground) when prompted with the 'Action Required' prompt.
I've tried to include as much relevant information as possible in hopes that someone may notice what I'm doing wrong and assist.
