Summary:
When sending the 'AKEYB' command with a custom prefix the command works as expected and sends the custom prefix. Sending another 'AKEYB' command without custom prefix will not show the default 'KEYB-' return prefix but incorrectly retain the previously assigned custom prefix.
Troubleshooting:
Issue resolved in firmware v1.11.42
