Communications Fallback

Communications fallback is supported on the V240m+ in standalone mode only for WiFi, GPRS and Bluetooth communication types.

For example, if your WiFi connection is a primary connection and is lost, the next connection method available that has been setup (say GPRS) should be used to keep communications to Verifone gateway alive.

Regarding the recovery of lost communications, if your primary communication was set as WiFi and had been lost previous but came back available, then the terminal would look to re-connect to the primary communication method available.

This recovery of connectivity to the primary communication can occur before and during the transaction process (before authorisation to Verifone gateway takes place).

Communication Method Priority List – Please note, this is a default configuration priority applied to all Engage terminal types.
