Hello everyone! I’m trying to write a key fob to a 5577 chip, but I keep running into an error. Has anyone encountered something similar?

It’s right there. Fix this and try again.

In case you’re unfamiliar, you need to pull down the latest code from GitHub and compile it… that should update your client, then flash the updated compiled firmware to your hardware and everything should match then. Then try your command again.
