Urgent help needed! Communication parameters of a large number of devices have been lost

We have a batch of beacon DW1000 devices. Their working mode is wake-up, transmission, reception, and hibernation, cycling every 5 seconds. After operating for one year, some of the devices have incorrect communication parameters and are unable to communicate. We suspect that the communication parameters have been restored to the default values. I would like to know what the default communication parameters are, and by sending specific data, we can make the devices restart.
