FK (Foreign Public Key) update over bluetooth XBee 3

0 votes
Until recently, I was able to easily enable bluetooth remotely on an XBee and then use my phone via the XCTU Mobile App to push the FK parameter so that I could then push OTA updates.

I use this method, because my remote XB are attached to a custom PCB that does not include USB connections - this was both cost concerns and the fact the world is out of FTDI chips.

Lately, when I follow the process above that always worked, I get the following error:

"Could not write setting 'FK' > There was a problem sending the AT command packet. > Invalid parameter"

I copy the 'FK' directly from another XBee unit and paste it directly - to avoid any missed characters and ensure it's exact.

What am I missing? Why doesn't this work anymore? Will I ever be able to push FK params remotely?

It was my fault ... my phone stopped "selecting all" and was missing the first few characters of the full key.

...if anyone sees this in the future - make sure you are really copying ALL.
