Recently we have had trouble sending certain commands to our handhelds. One of the most common ones we have seen is the error message below when sending the Check-in Command.

ERROR

Error sending the Check-in action to 1 device(s).

When I go to the logs for this device, it shows the request for the Check-in but does not show it as resolved on the next line like it would when it normally works.

Is this a known issue? Further details below:

Handheld Models: TC56 + TC57
