Primary Responder mode

You can use the Primary Responder mode configuration setting to manually enable the TX54 device to be in an AT&T FirstNet-compliant mode (Primary Responder mode). When a device is in Primary Responder mode, certain firmware features are disabled. See Differences between standard firmware operation and Primary Responder mode.

The Primary Responder mode configuration setting is available in the 23.9.x and newer firmware. This replaces the Primary Responder firmware that was available prior to the 23.9.x firmware release.

Primary Responder mode is automatically enabled if the device has a FirstNet SIM card

If your device has an AT&T FirstNet SIM card installed, the Primary Responder mode configuration setting is automatically enabled when the TX54 device connects to the AT&T network.

If you have a configuration template setup for your PR device running firmware older than 23.9.x, you will need to create a new configuration template after updating firmware on your device.

Disable Primary Responder Mode

If you enable Primary Responder mode and then disable it, the device's configuration is erased and the device will reboot. You will then need to reconfigure the device to the desired configuration.
