OTA Failure

[mateusz-]

Hello,

I am using this library to perform an OTA update on my company's product. I started off with the RemoteFirmwareUpdateSample.py. During the update, I see the following output:

Starting firmware update process...

I abbreviated some output above with "...". I verified the firmware update actually succeeded by using the VR command. In the output above, I updated from the "XBP9X_9004.ebin" to "XBP9X_9009.ebin", which I obtained from XCTU's installation. My product is using the XBee SX module. ATVR, ATHV and ATHS return the following:

ATVR: 9009
ATHV: 3146
ATHS: A00

I obtained the XBee Python library from pip. The version I am using is 1.4.1.
